75 KVA Automatic Voltage Stabilizer Main technology characteristics
A. Input voltage:
Three-phase: three-phase four-wire phase voltage 220±20%, wire voltage 380V±20% or phase voltage 220±30%, wire voltage 380V ± 30%.
B. Output voltage:
Three-phase: three-phase four-wire phase voltage 220V, wire voltage 380V
C. Accuracy of output voltage: 2-5% (adjustable)
D. Efficiency: ≥95% (power class: more than 50KVA)
E. Response speed: ≤1.5S (when outside voltage has 10% of change)
F. Waveform distortion: no additive waveform distortion
G. Protection: protection against over voltage, over current, phase failure and machine fault, as well as phase
H. Voltage stabilization, convenient switching for commercial power
I. Start automatically or by hand (can be chosen) when power is on.
J. Can work continuously for a long time without anybody attending.
K. Insulation resistance: ≥2MΩ
L. Electric strength: bear power frequency sine voltage 2,000V for 1 min without breakdown or flash over.
M. Overload capability: 2 times rated current, keeping 1 min (voltage stabilizer special for elevator and CT)
