Product Introduction

240V high voltage DC (HVDC) power supply, is a new power distribution form for data room that adopts high voltage DC power supply to improve the power purity and efficiency, reduced the fault point by reducing the inverter links, mainly apply to operators and BAT corporate clients.

Product Features

AC input voltage adapt to a wide range, within the range 313 VAC ~ 516 VAC, output rated current, within the range of 200 ~ 312VAC, can be derating output
Rectifier adopts the active power factor correction technology, to make the input AC current waveform keep same with voltage waveform at same phase for get high power factor and the whole machine efficiency, so it could save energy, reduce costs, reduce operating costs;
The rectifier adopts the high frequency soft switch PWM control transformation technology. On the one hand, it reduces the power loss in the high-frequency switching process and improves the efficiency of the whole machine.On the other hand, the electromagnetic interference can be reduced, the other communication equipment could be installed in the power system.
Various parameter detection, realize the power module real-time comprehensive monitoring;
