(can be selected.Please specify when ordering.)

Output voltage

Phase voltage:220V Single-phase:220V Line voltage:380V

Output voltage accuracy

2-5%(can be adjusted) Frequency:50HZ/60HZ

Efficiency

≥98%(Power grade is over 50KVA)

Ambient temperature

-10~+40°C

Insulation resistance

≥2MΩ

Electric intensity

The voltage for electrical strength and power frequency sinusoidal is 2000V without breakdown and flash over when lasts 1minute

Protective function

it offers the protections against over voltage,over current,phase shortage and phase-sequence(The single-phase offers no protection against the phase shortage and phase-sequence)and mechanical failure
