The SVC series three-phase high-precision automatic voltage regulator consists of a contact autotransformer, servo motor, and an automatic control circuit. When the grid voltage fluctuates or the load changes, the automatic sampling control circuit sends a signal to the servo motor, adjusting the position of the carbon brush on the autotransformer to maintain a stable output voltage.
This high-precision three-phase AC-regulated power supply is composed of single-phase SVC series regulators. It utilizes phase-by-phase adjustment to ensure stable and reliable voltage for each phase. The system operates with a three-phase, four-wire input in a star (Y) connection. The output can be configured as either a three-phase four-wire or three-phase three-wire system. Additionally, three current meters display the output current for each phase, while a converter switch and a voltmeter allow for phase output line voltage monitoring.
