3 phase battery charger power supply

l Output overvoltage protection

To prevent the disastrous accident caused by output overvoltage to electric consumers, there is overvoltage protection circuit in the module. When 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.

l 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

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.

l Module parallel protection

There is parallel protection circuit in each module to ensure that when the fault module quits the system, the normal work of other modules and the system won’t be effect.

Over-temperature protection

Over-temperature protection is mainly for protecting large power converters, under normal operating circumstance, the module design leaves enough margin, under special circumstance, when the module detects that the temperature of the radiator is over 90℃, it will shut down automatically to protect itself. When the temperature of radiator get down,  the module will restart work automatically.

l Output over-current protection

Because of the limit of the module output power, the output current cannot increase infinitely. In the range, the output current value of the module is continuously adjustable. If overloaded, the module can reduce output voltage automatically to make it not surplus the rated output limit point in order to protect the power components. The over current protection can be resumed automatically.
