Load   grade

Grade I (100%) rated output current works   continuously

In the range of float charging voltage

Automatic   current limiting characteristic

The output current exceeds 110% of rated   current

For the constant power protection, the   output current shall not increase, and DC voltage shall drop

Input overvoltage/low-voltage protection

The module is with   overvoltage/low-voltage input protection function. When the input voltage is   less than 313±10Vac or greater than 485±10Vac, the module shall protect, no   DC output, and the protection indicator light (yellow) shall be on.

After restoring the voltage to 335±10Vac~460±15Vac, the module shall work   automatically.

Input phase loss protection

When the input is lack of phase, the   module shall limit the power output. When the output voltage is 260V, 5A   current is output.

After fault clearance, it shall work automatically   and normally

Output   overvoltage protection

The output shall stop automatically if   the output voltage is more than 293±6VDC, in case of damaging the equipment

The module cannot recover automatically,   switch on the module again after switching off it.

Output   low-voltage alarm

When the output voltage is less than   198±1Vdc, the module shall alarm, there is DC output, and the protection   indicator light (yellow) shall be on.

After the voltage is recovered, the   module output low-voltage alarm shall disappear.

Output short circuit retraction function

When the module output is short out, the   output current should not be greater than 40% of rated current.

After fault clearance, it shall work   automatically and normally

Over-temperature protection

If the temperature inside the module is   higher than the set value, the module over-temperature protection function shall   start, the protection indicator light (yellow) of the module panel shall be   on, and the module has no voltage output.

After the abnormal condition is removed   and the temperature inside the module is normal, the module shall work   automatically and normally
