20KVA - 300KVA Rack UPS Power Supply For Computer Communication

Product Specification

N Series 20-300KVA UPS

Three in and three out UPS power supply. The product adopts modular design and n+x parallel redundancy technology. The product capacity covers all power segments between 20KVA and 300kVA, which is convenient for users to flexibly configure and gradually invest. This series of UPS can almost completely solve all power supply problems, such as power failure, mains high voltage, mains low voltage, voltage instantaneous drop, amplitude reduction oscillation, high voltage pulse, voltage fluctuation, surge voltage, harmonic distortion, clutter interference, frequency fluctuation, etc.

This UPS product has a wide range of applications, from computer equipment to communication system and automatic equipment.

Digital control

• the architecture of all parts of this series of UPS adopts digital control. All performance indicators of ups are very excellent, and the control system is more stable and reliable; Each module has built-in automatic bypass switch and corresponding bypass current sharing inductor, providing good current sharing performance of system bypass power supply

High power density modular design

The single module capacity is 20kva/25kva/30kva, and the height of all modules is 3U; UPS module can be added and pulled out online to realize "zero" maintenance time

• the appearance of 19 inch standard cabinet is elegant, which can perfectly match the application environment of the computer room and save the use area of the computer room; 5 modules are installed in the 1.4m high cabinet and 10 modules are installed in the 2m high cabinet

N+x parallel redundancy

• the number of redundant modules can be set arbitrarily. When the number of redundant modules reaches more than two, the system availability reaches 99.999% and the MTBF (mean time between failures) reaches more than 250000 hours; Support parallel connection between cabinets, with a maximum number of 4 cabinets; Shared battery pack during parallel operation

Smart battery management

• the user can set the charging current, and the constant current, constant voltage and floating charging modes can be automatically and smoothly switched

±192Vdc/±204Vdc/±216Vdc/±228Vdc/±240Vdc(32/34/36/38/40节可选)

• the battery voltage can be configured arbitrarily ± 192vdc/ ± 204vdc/ ± 216vdc/ ± 228vdc/ ± 240vdc (32/34/36/38/40 sections are optional)

• large LCD display in the cabinet, with touch function, Chinese / English bilingual; Single module lcd/led display

Safe and convenient maintenance

• in case of emergency, it can be switched to maintenance bypass power supply, and maintenance personnel can safely conduct online maintenance; In case of emergency, press EPO button to shut down the machine; And it has remote emergency shutdown (repo) function

 smart management

• centralized monitoring module (with hot plug function)

• rs232/rs485 communication interface

• SNMP card (optional), which can realize remote monitoring of UPS

• relay card (optional)
