Battery Charger 240VDC-20A

Main characteristic of the module

lModularization design, realize N+1 backup;

lThe friendly man-machine interface. Large screen to show, realize man-machine dialogue operate really.

lRS-485 inrerface, realize “4 remote” function with monitor machine.

lHigh efficiency, Nearly 95%-96%;

lLightly, 230V/10A natural cooling module only 9kg;

lLittle volume, 230V/10A natural cooling module dimension only 325mm×230mm×130mm;

lAfter the full bridge rectifying circuit rectifies 3-phase AC to DC, then adjusted by reactive PFC, power factor>0.94;

lFunction against reverse pour: each module has been added diode against reverse pour at output terminal.

lLED digital screen, digital calibrate, stable current ,fault alarm

lOutput overvoltage protection

   To prevent the disastrous accident caused by outputting overvoltage to electric consumers, there is overvoltage protection circuit in the module. After output overvoltage occurs, the module locks up automatically, the relative module fault indication light is on, the faulty module quits work automatically and doesn’t affect the normal operation of the entire system. The overvoltage protection point is set when ex-factory, 320V±5% is set for rated output 220V machine type, 160V±5% is set for rated output 110V machine type.

lOutput 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.

l  Output short-circuit protection

When output short circuit, the module draws the output voltage to 0 immediately, limit the short circuit current below 15%limit current point to protect the module. The module will not be damaged under short circuit state for a long time, and can go back to work automatically after debugging.
