Product Description

AC/DC Battery Charger 480V-80A/100A/150A

 

The charger rectifiers are designed with world leading patent technology “resonant voltage type soft switching power supply technology”. They feature high efficiency and stability, intelligent control, small size and light weight.

380V series natural cooling rectifiers ranges has two series according to input voltage grade. A variety of current output optional, 10A 20A 30A 40A, 50A 60A 80A 100A 120A 150A are big power rectifier especially designed for the power plant, substation and hydropower station.

 

Main characteristic of the Modules

  • The friendly man-machine interface. LED digital screen, digital calibrate, stable current ,fault alarm
  • High efficiency, up to 95%-96%;
  • Light weight, Small size
  • After the full bridge rectifying circuit rectifies 3-phase AC to DC, then adjusted by reactive PFC, power factor>0.94;
  • Unequal current ratio of parallel connection+/-3%, can ensure twenty modules work well by

parallel connection.

  • Multiple protections including over/under voltage, current limiting, short-circuit, parallel protection, over-temperature protection.
  • Output over-voltage protection

To prevent the disastrous accident caused by output overvoltage, there is overvoltage protection circuit in the module. Once the output voltage is higher than the threshold, the module locks up automatically and fault indication light is on, the faulty module quits work automatically and doesn’t affect the normal operation of the entire system.

  • Output current limiting protect

The output current cannot increase infinitely. The maximum value of the output current of each module is limited to the rated output current 105%, in this range, the output current value of the module is continuously adjustable. If the load output of the module, the module will play down the output voltage.

  • Output short-circuit protection

When short circuit, the output voltage drops to 0 immediately. Limit the short circuit current under 15% of rated output current. The module will not be damaged under short circuit state for a time, and resumes to work automatically after debugging.
