With the development of system integration, computer rooms and data centers, higher requirements have been put forward for rack-mounted UPS power supply.

　　Today, the editor of Cuneng Electric will explain in detail the technical requirements and future development trends of rack-mounted UPS power supply. Save it quickly!

　　Foreword:

　　As IT systems gradually move towards centralized management, enterprises will have more in-depth application of rack-mounted UPS power protection systems. UPS power supply system is a high-tech product developed in response to the needs of the power market. It has obvious power protection functions. UPS power supply is a new type of power supply that mainly applies comprehensive automatic control, semiconductor devices, microprocessors and electromagnetic technology. On the premise of achieving energy conservation and emission reduction, the requirements for power supply quality in special places are guaranteed.

　　The quality and technical performance of the rack-mounted UPS product itself is only one aspect of the product. Without corresponding services, its work is incomplete. With the popularity of UPS power supply in the Chinese market, the service and support system of UPS power supply has also been continuously improved. And development, high-reliability UPS power system coupled with a complete after-sales service system will be the fundamental guarantee to satisfy the majority of UPS power users.

　　Power supply technical specifications requirements for rack-mounted UPS power supply:

　　●Technical indicators related to mains electricity

　　The rack-mounted UPS power supply must be able to operate normally under local mains power conditions and not have any adverse effects on the mains power. Performance indicators in this area include:

　　(1) The allowable variation range of mains voltage;

　　Low temperature and high energy density 18650 3350mAh-40℃ 0.5C discharge capacity ≥60%

　　Charging temperature: 0~45℃ Discharge temperature: -40~+55℃ Specific energy: 240Wh/kg -40℃ Discharge capacity retention rate: 0.5C Discharge capacity ≥ 60%

　　(2) Allowable mains voltage waveform distortion;

　　(3) Allow the imbalance of mains power;

　　(4) Allowable mains frequency variation range;

　　(5) UPS power supply input power factor;

　　(6) Harmonic components of UPS power input current.

　　●Rack-mounted UPS power output capability and reliability

　　For users, the rack-mounted UPS power supply is required to have sufficient output capability and reliability, otherwise it will affect the operation of the load and even constitute a new source of failure. These indicators include:

　　(1) Operation efficiency;

　　(2) Output current peak coefficient (periodic peak load);

　　(3) Output current surge coefficient (non-periodic peak load);

　　(4) Output overload capability;

　　(5)Output power factor.

　　●Conventional output indicators of UPS power supply that meet load requirements

　　Rack-mounted UPS power supply must meet load requirements and improve power supply quality. These indicators include:

　　(1) Output voltage stability accuracy;

　　(2)Output voltage waveform distortion;

　　(3) Output voltage imbalance;

　　(4) Output voltage frequency stability;

　　(5) Conversion time when mains power fails;

　　(6) The maintenance time for continued power supply after the mains power fails;

　　(7) Anti-interference configuration and anti-interference function.

　　●Intelligent management and communication functions

　　(1) Automatic detection, display, alarm and operating parameter setting functions;

　　(2) Local intelligent management interface;

　　(3) Network management, dedicated power monitoring software, supports SNMP network management, supported management platforms and corresponding certifications;

　　4) Network communication, supporting network information transmission based on TCP/IP;

　　5) Based on public network communication, support information transmission based on public telephone network.

　　Future development trends of rack UPS:

　　Integration: With the development of informatization, the application fields of power protection continue to expand and the requirements continue to increase. To meet these requirements, it is difficult for rack-mounted UPS to meet these requirements alone. All links involved in the entire power system must be controlled.

　　Intelligentization: Through the analysis and synthesis of various types of information, the intelligent system should not only complete the control function of the normal operation of the corresponding parts of the UPS, but also complete the real-time monitoring of the running rack-mounted UPS and analyze the important data information in the circuit. Processing, from which we can determine whether each part of the circuit is working normally and other functions; when the UPS fails, it can be analyzed in a timely manner based on the detection results.

　　Redundant parallel technology: Through the development of new application technology, multi-module redundant parallel operation in the UPS can be realized without the need for additional central control components. The load is evenly distributed. When a problem occurs in a certain module, the load is automatically transferred. It can be hot-swapped and unplugged during maintenance, which greatly improves the power supply reliability of UPS.

　　Digitalization: UPS uses the latest digital signal controller (DSP) and digital Hall sensor devices to achieve 100% digital operation of the UPS system.

　　Greening: Harmonic currents generated by various electrical equipment and power supply devices seriously pollute the power grid. With the introduction of various policies and regulations, the call for pollution-free green power supply devices is getting louder and louder.
