2.Input range 150V-250V; 70V-130V
3.Output:220V+/-3%; 110V +/-3%.
4.short time delay and over voltage protection
SBW three phase compensated voltage stablilizer is a contact adjustable automatic voltage compensation high-power 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.
1. Whole power-supply of small type factory.
2.Workshop and department power-supply of large, middle type industrial and mining enterprises.
3.Form a complete set with single-machine.
1. Ambient temperature of use: 0°C~40°C.
2. Ambient temperature of storage and transport: -40°C~60°C
3. Relative humidity: <90%
4. Without corrosive, flammable and explodable, gas and other conductive gas which might influence insulation of voltage regulator.
1. Input: three phase and four-line system Voltage: 176V~250V Line voltage: 304V~432V
2. Output: three phase and four-line system Voltage: 210V~230V Line voltage: 361V~399V
3. Input & output terminal (phase line and middle line) can bear sinusoidal voltage with power frequency 50Hz 3000V to machine stand for 1 minute.
It is better than 98% if voltage regulator operates with normal power.
5. Additional waveform distortion of output voltage<1%
