The SVC-1.5K is a full-automatic three-phase AC voltage stabilizer that combines a contact autotransformer, servomotor, and automatic control circuit. When grid voltage or load changes, the sampling control circuit sends a signal to the servomotor, adjusting the carbon brush position to stabilize the output voltage.
This model ensures distortion-free waveform, reliable long-term performance, and includes time delay, over-voltage, and under-voltage protection. Each phase is regulated independently to maintain safe and steady voltage. It supports both three-phase four-wire (Y) and three-phase three-wire output configurations. Ampere meters display current per phase, and a switch with voltage meter shift allows phase-by-phase voltage monitoring.
