It is automatically restarted every 30 seconds. After the fault is removed, it can be restored. Long-term short circuit, the power off lock, re-boot can work properly.Over current protectionWhen overcurrent is detected, the power is turned off and an alarm signal is issued. When the load returns to the rated value, it can be restored. Long-term overload, the power off lock, re-boot can resume normal work.Alarm function(sharp alarm)DC input abnormal, overload, short circuit, inverter failure, the wind alarm, while warning lights.AmbientOperating temp.-5~+40ºC Storage inverter temp.-25~+70ºC Relative humidity0~95% Altitude3000m CoolingForced air cooling Operating ambientNo conductive explosion of dust, no corrosion and damage to the gas and steam, no severe vibration and shock.InsulationParameterStandard requirementRemarkDielectric strengthInput-output:2000Vac/10mA//1minNo flash, no breakdownInput-earth:500Vdc/10mA//1minOutput-earth:1500Vac/10mA//1miInsulation resistanceAt normal atmospheric pressure, the relative humidity of 95%, the test voltage is DC 500V, the power input to the output, input to the ground, the output to the ground insulation resistance of not less than 10MΩ.EMCConductioncomply to standard YD/T983-1998 ARadiationcomply to standard YD/T983-1998 AImmunitycomply to standard YD/T983-1998 ANoise<55dB(1meter)The shell protection levelIP20(indoor)SmellNo smell and other harmful smell to healthMechanicalDimension481.6*270*88.1 mm Weight≤4KG
