    UPS capacity selection


    Select the UPS capacity based on the following factors, characteristics, calculated load, shock current, peak current, overload capacity, and load abrupt change. The payload capacity is compensated by the following values.

    1. About impulse current
    Calculated capacity of UPS capable of withstanding peak current = payload capacity X impact current (maximum)/rated current of UPS, which is generally 5-10 times the effective capacity.
    The load is put into the power supply and generates a considerable shock current, especially for computers and peripherals. During UPS power supply, in order to reduce the capacity of UPS, load is put into or selected for UPS mains power operation. When the current returns to the rated current value below, the power is converted to the rectifier and the inverter is supplied.


    2. About peak current
    UPS capable of withstanding peak current;
    Capacity = payload capacity X peak current (maximum)/rated UPS current;
    Peak capacity is generally 2 times of effective capacity;
    For UPS with a peak coefficient of 2.5 or above, the peak current bearing capacity is 250%PA, which generally does not exceed the rated capacity of UPS and can be directly used without compensation.


    3. Overload
    The overload capacity of UPS is generally more than 1.1 times of the effective load. If the load overload is more than 1.1 times, UPS shall be protected.
    4. Sudden change of load
    Most UPS load changes are within the range of 0 "100%, and the output voltage fluctuation can be controlled within -10%I~A. Therefore, no compensation can be made for the payload capacity.
    5. Generator-ups cooperation
    In some places the UPS switches to a self-contained generator after a power outage. When the self-provided generator supplies power, it should be able to provide a large shock current when the UPS starts without affecting the operation of the generator.
    1) select the rectifier device with a lower starting current UPS. For example, for a 12 pulse rectifier, the self-provided generator should have twice the capacity of the rectifier
    2) select several sets of UPS for parallel connection and group delay start. It can be combined with slope start function to avoid excessive shock current caused by simultaneous start of all UPS.
    3) select a UPS with rectified charger input power and controllable power, and make the rectifier charger input part of power, while the insufficient power is provided by the battery.
    4) choose UPS with limited charging current function. When the generator is started up and running, limit the charging and set the charging current value to 0 Abe. That is, the charging can be stopped while the generator is running, thereby reducing the amount of power the UPS absorbs from the generator.

    Choose Wisely The Four Elements of Modular UPS

    With a wide range of UPS products, schneider electric believes that only four factors need to be considered to end the selection difficulties.
    As the guardian of power, UPS provides a stable and uninterrupted power supply for key load equipment in various industries to protect them from overload, short circuit, surge and other power hazards, so as to ensure the normal operation of the business. With the rapid development of cloud application and cloud hosting, the protection of connection and data storage device is even more important. How to select UPS suitable for professional network, so that the variety of UPS products can be distinguished? Schneider electric, a global expert in energy efficiency management and automation, points out that there are four key factors to consider when choosing UPS, which can help companies choose products that suit their business needs.


    UPS size
    According to a recent study by cisco, the number of mobile devices will soon outnumber the global population. This era of BYOD and mobile devices poses a huge challenge for IT managers to stabilize enterprise networks and connections. In addition to ensuring proper server operation, it is equally critical to protect storage and network devices, broadband connections, access points, modems and routers from potential damage caused by power transients and to maintain business continuity. Consider the rate of growth of the IT infrastructure when sizing UPS and determine how much "redundancy" is needed for short-term growth.
    UPS scalability
    If the enterprise cannot predict the future trend of its IT infrastructure, then using scalable standard UPS is one way. But if future demand is uncertain or only growing rapidly, modular UPS can provide an effective solution for enterprises. Modular UPS is expandable and can support future load and run expansions through increased power module cabinets rather than system-wide replacements. A pay-as-you-need approach helps match UPS and IT power, improves system efficiency, and minimizes operating costs.
    UPS backup time
    In the United States, most blackouts last from five minutes to an hour. To cope with prolonged power failure, the data center needs to be equipped with multiple mains power input or backup generator sets. Because ATS or backup generators can be switched on or started in less than a minute, UPS typically requires only 5-15 minutes of energy storage battery configuration. At the same time, UPS should be compatible with lead-acid battery and lithium battery to meet the needs of future energy storage development.

    UPS management
    DCIM data center management software can provide convenient remote monitoring and control for IT administrators; While active battery and environmental diagnostics can greatly reduce downtime; Advanced UPS management helps optimize system operation, safely shut down the system, and protect data and equipment from crashes caused by power outages.

    The Advantages of A Rack Modular UPS

    Today, Our main goal is to talk about the advantages of a rack modular UPS.
    NETCCA-The Advantages Of A Rack Modular Ups, Netcca Technology Group
    What are the advantages of rack modular UPS?
    Parallel redundancy, stable operation, and high reliability


    In rack modular UPS, the power module part is redundant in parallel, and each module is equipped with input and output insurance and input and output relay. Failure of any module will not affect the work of the whole system.
    In traditional UPS products, users generally adopt "1+1" or "N+1" parallel redundancy mode to ensure safety, which can only tolerate fault once. In the rack modular UPS system, users only need to purchase the corresponding power module to achieve "N+X" fault redundancy. "Modular redundant parallel" is more reliable than traditional UPS.
    Easy maintenance, online disposal, high availability
    Traditional UPS requires professional and technical personnel to go to the site for maintenance. All modules of modular UPS are allowed to be hot-plugged, and users can intervene for maintenance and directly replace UPS spare modules online.
    Rack modular UPS inherits the development achievements of traditional UPS technology in terms of power device technology and manufacturing process, but in terms of system architecture, based on the parallel connection of multiple modules, it not only realizes the hot plugging of system modules but also better handles the relationship of system module operation, mutual cooperation, and smooth conversion.
    The modular rack UPS is a typical structure at present


    One is power modular UPS. The power module is composed of rack and power module, which includes the rectifier, filtering, charging, inverter and other parts of traditional UPS. But the static bypass shares the same rack with some of the system's monitoring and display. Each module controls the parallel operation. The display control module on the upper part of the cabinet only serves as the user switch UPS host and network monitoring platform.
    The other type is completely modular UPS. This kind of rack modular UPS is composed of rack and single module, every single module is equipped with the whole UPS power supply and control circuit, including rectifier, inverter, static bypass switch and attached control circuit, CPU main control board. Each UPS module has its own management system.

    Inverter power manufacturer Netcca briefly analyzes the concept of inverter efficiency

    Many people are very vague about the concept of inverter efficiency. In view of this problem, the inverter power supply manufacturer Netcca is discussing and analyzing with you today. First of all, we need to understand what is the inverter efficiency of inverter power supply? Through this article, we introduce the whole machine conversion efficiency in inverter efficiency. As below is our Inverter 10KVA.
    NETCCA-Inverter Power Manufacturer Netcca Briefly Analyzes The Concept Of Inverter
    Inverter efficiency is related to the overall efficiency of design, so many designers pay close attention to it. In the case of inverter efficiency, the characteristic of conversion efficiency is that its efficiency is always less than 1. This is because the inverter circuit inside the inverter will produce certain losses. Due to the partial energy consumption, the output power is smaller than the input power.


    The efficiency of the inverter is the ratio of the input dc power to ac power. That is, the ratio between the input dc power received by the inverter and the output ac power to the grid through partial filtering. Whole machine conversion efficiency mathematical expression formula: inverter conversion efficiency = inverter output power/inverter dc input power xl00%.

    The ten most basic protected functions of Netcca UPS


    1). Voltage stability - a mains voltage is affected by the quality of electric power transmission line, the closer from the substation of the user high voltage of about 130 ~ 120 v, from low voltage substation remote users about 100 ~ 90 v, the voltage is too high or too low will the user equipment life, serious when burning equipment, use of on-line UPS power supply can provide stable voltage, voltage fluctuation is less than 2 v, can extend the life of the equipment and protection equipment.As below is a netcca product recommended:
    2). Power failure protection: in the case of power failure, the battery is immediately converted from dc power supply to ac power supply by UPS uninterrupted power supply.As below is a netcca product recommende
    3) high-low voltage protection -- when the voltage of a power supply is too high or too low,UPS built-in voltage stabilizer (AVR) will make appropriate adjustment to keep the voltage of the power supply in the usable range. If the voltage is too low or too high to exceed the usable range,UPS will convert the battery dc power supply to ac power supply to continue to protect the user equipment.As below is a netcca product recommended:
    4). Frequency stability -- a power supply frequency is divided into 50Hz/60Hz, the so-called frequency is the cycle of every second,50Hz is 50 cycles per second, Taiwan power supply frequency is 60Hz, the mainland is 50Hz. When the generator is running, the rotation speed will fluctuate due to the sudden change of the power consumption of the client. The power converted by UPS uninterruptible power supply can provide a stable frequency.
    5) waveform distortion processing -- because the power is transmitted to the client through the transmission and distribution lines, the use of various machines and equipment often causes distortion of the mains voltage waveform, because waveform distortion will generate harmonic * equipment and will make the power system transformer temperature rise, generally required distortion rate <5%, generally UPS design distortion rate <3%.
    6) monitoring power supply: with the intelligent communication interface and monitoring software of UPS, the power supply can be monitored by recording the mains voltage frequency, power failure time and frequency, and the schedule of UPS uninterruptible power timing switch can be arranged to save energy.

    7). Suppression of common mode noise - common mode noise is generated between the live wire/neutral wire and ground wire.
    8). Suppress horizontal mode noise -- -- a horizontal mode noise is generated between the live line and the neutral line.
    9) surge protection: generally UPS UPS uninterruptible power supply will be equipped with surge absorber or tip discharge design to absorb surge to protect user equipment.
    10)instantaneous response protection: when the power supply is affected by *, it may cause voltage bulge or sag or instantaneous voltage drop. The on-line UPS can provide stable voltage and make the voltage change less than 2V, which can extend the service life of the equipment and protect the equipment.

    Why We Use UPS Power?

    UPS power supply (on-line) has three basic functions:

    1. Uninterrupted power supply;
    2. Stable voltage and frequency;
    3. Municipal power purification function;


    Two or three features in particular may be overlooked.


    As you know, in many places, there is a serious contradiction between supply and demand, the improvement of the power grid is not satisfactory, and insufficient or unstable power supply is a common phenomenon. Although your computer can be started up normally under these circumstances, you do not know that frequent dynamic fluctuations of voltage and frequency (especially during peak power consumption) will make your computer's internal sensitive electronic components wear out greatly, reducing its service life. Although the computer is equipped with corresponding switching power supply, but in the face of poor power grid, the actual effect is limited.

    As is known to all, a lot of electrical equipment do not have green electricity conditions also extensive use on power grid, the busy rush surge, higher harmonic, clutter noise such as feedback to the public power grid, power grid caused by secondary pollution, the damage to the user the use of computers, can cause the malfunction of computer internal components, cause the data to computer somehow lost its second, file disorder, but also easy to make the computer internal components wear overheating and accelerated aging.

    According to the simulation experiment of relevant power supply experts at home and abroad, it is concluded that the use life of PC can be extended by 0.35 times if the PC is equipped with UPS power supply, while the cost of configuring UPS only accounts for 0.05-0.08 times of the computer. What's more, UPS can also play the function of delaying uninterruptible power when the computer is in power failure. Therefore, there is no reason why you should not configure UPS when you buy a computer!(more details,please visit)

    Simply discuss the importance of UPS

    UPS, or uninterruptible power supply, is an uninterruptible power supply with energy storage device and constant voltage and frequency with inverter as the main component. Its main function is to provide uninterrupted power supply for a single computer, computer network system or other power electronic equipment. When the mains input is normal, UPS uninterruptible power supply stabilizes the mains voltage and provides load for use,At this time, UPS uninterruptible power supply is equivalent to an ac municipal voltage stabilizer, and it also charges the battery inside the machine; When the power supply is interrupted, UPS will immediately supply 220V ac power to the load through inverter conversion, so as to maintain the normal operation of the load and protect the software and hardware of the load from damage.



    According to the statistics of our professional UPS power website -- Netcca website (www.netcca.com.cn), there are a large number of common UPS power supply types in our factory at present, with a total of 163 kinds of UPS power supply products. Facing so many UPS power supply products, which one is more suitable for you?


    At present, the average power consumption of a computer is about 250VA, and a backup 500VA UPS can provide power for about 10 minutes. This is enough time to make sure you have enough time to save the file and shut down the computer properly. If you have multiple computers at home, you can calculate the total power by yourself, and then select the appropriate UPS capacity. For some specific commercial and industrial applications, the calculation is much more complex. The requirement of these departments for UPS is to ensure that dozens of computers can work continuously for more than ten or even dozens of hours when the power grid is cut off.

    In addition, UPS uninterruptible power supply as a protective power supply equipment, its performance parameters have important significance is one of the key considerations when we buy. The wide input range of mains voltage indicates the strong utilization ability of mains (reducing battery discharge). A small range of output voltage and frequency indicates a strong ability to adjust the power supply and stable output. Waveform distortion rate is used to measure the stability of output voltage waveform, while voltage stability indicates the stability of output voltage when UPS suddenly increases from zero load to full load. In addition, UPS efficiency, power factor, conversion time and other important parameters that characterize UPS performance determine the protection capacity of load and the utilization rate of mains power. The better the performance, the stronger the protection ability. In general, off-line UPS has the worst protection for load, while online interactive UPS is slightly better. Online UPS can solve almost all common power problems.



    Generally, online UPS has a high price, but its protection function is very perfect. It can filter out all kinds of viruses parasitic on most power grids and fully guarantee the stability and safety of load equipment. Backup UPS is small in size and low in price. It can also prevent data loss caused by power failure for some equipment systems that are not particularly important.

    If economic conditions allow, of course, the first online UPS. However, from the perspective of economy, a backup UPS power supply is enough for ordinary families or ordinary office places with low requirements.
