● Three phase (three-phase four wire) 380V ± 20% or 380V ± 30% (to be specified when ordering)
● Output voltage:
● Three phase (three-phase four wire) line voltage 380V or phase voltage 220V
Output voltage accuracy: (2-5%) adjustable
● Frequency: 50-60Hz
Efficiency: ≥ 95% (power level above 50KVA)
Response time: ≤ 1.5s (when external voltage changes by 10%)
● Waveform distortion: No additional waveform distortion
● Protection function: With overvoltage, overcurrent, phase loss, phase sequence protection (single-phase and three-phase 150KVA or below without phase loss and phase sequence protection) and mechanical faults ● Mains function: three-phase products have convenient switching of mains and voltage stabilization (single-phase does not have this function)
● Starting method: Power on automatic start or manual start can be selected
● Working mode: capable of long-term and continuous unmanned work
Insulation resistance: ≥ 2M Ω
Electrical strength: The power frequency sinusoidal voltage is 2000V, and there is no breakdown or flashover phenomenon for 1 minute.
