Usually serves as power supply for engine bed control electric appliance or the partial flare and indicating lamp.Working environment1. Ambient air temperature: -5oC~+40oC, the highest monthly mean temperature should not exceed +35oC;2. Altitude for installing place should not exceed 2000m;3. When the ambient air temperature is +40, the relative humidity should not exceed 50%, and it allows higher relative humidity under lower temperature. Max average humidity in the dampest month is 90%, meanwhile the lowest average temperature of this month is +25oC, and condensation on the product surface caused by temperature change should be taken into consideration.Datasheet:Primary voltage220V 380VAC ...Secondary voltage:380V, 220V, 110V, 36V, 24V, 12V, 6V...
