Voltage waveformSine wave THD <3% (linear load)Sine wave THD <8% (Non-linear load)Over load capacity105 ~ 125% for no less than 60 s, 125 ~ 150% last not less than 1 0 sOutput current peak-peak coefficient3: 1OutputA wiring row outputWorkingMains priority; when the mains over/under voltage or power down, the bypass start up, time≤5ms. When the mains working normally, mains start up, time≤5ms.

ProtectionParameterMin.TypicalMax.UnitNoteDC input under voltage protection set point37 40VdcTest with half loadDC input under voltage recovery set point40 43VdcReach the recovery value, auto-recovery.DC input over voltage protection set point58 60VdcTest with half loadDC input over voltage recovery set point56 58VdcReach the recovery value, auto-recovery.Bypass input under voltage protection set point160 180VdcTest with half loadBypass input over voltage protection set point260 280VdcTest with half loadOver Temperature ProtectionPower supply with over-temperature protection. When the temperature inside the main radiator, reaching over temperature protection set point, turn off the output, temperature hysteresis of 1 0 ºC or so.Anti-reverse protectionPower supply with input anti-reverse protection. When the input reverse polarity, the power stop working, and no damage.Short circuit protectionPower supply with output short circuit protection. Short circuit is detected, the output power is turned off and an alarm signal every 30 seconds automatically restart once the fault is removed, auto-recovery. Long-term short circuit, power off lock, reboot to work.Over current protectionPower supply with output over current protection. Over current is detected, the output power is turned off and an alarm signal when the load back to the rated value, auto-recovery. Long-term overload, power off lock up, reboot to resume normal work.Alarm (buzzer alarm)DC input abnormal, overload, short circuit, inverter fault, the buzzer alarm and warning light on.
