| Ripple factor | 0.01%~0.1% | 0~20MHz bandwidth | ||
| Dielectric strength | 2000VAC 50Hz | Time is 1 minute, leak current is 10mA | ||
| 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 | ||
