Origin China Model Number SBW SBW voltage stabilizer is an adjustable automatic voltage compensation regulating power device. When voltage from supply network is varied or due to loading current effect, it automatically regulates the output voltage to ensure the normal function of the varied of electric equipments. Specification Input voltageSingle phase:220V;Three phases:380V Output voltage: Single phases:220V+-20% or 220V+-30% Three phases four-line:380V+-20% or 380V+-30% Phase: Single phase;Three phases four-line Frequency: 50Hz/60Hz Response: Within 1 sec.(against 10% input voltage deviation) Efficiency: Better than 95% Ambient temperature: -10-+40 Waveform: Non-lack fidelity waveform Insulation restortion: Better than 5M Overload: Double rated current,one min Protection: Overvoltage,overcurrent, feed phases
