3 Phase 10kVA Servo Motor AVR

The 3 Phase 10KVA Servo Motor AVR is a mature AC voltage stabilization product composed of key components such as a columnar contact voltage regulator, sampling circuit, protection circuit, control circuit, low-speed synchronous motor mechanism, and compensation transformer.

When fluctuations occur due to unstable mains voltage or changes in user load, the sampling circuit processes the voltage signal and sends it to the synchronous motor. This drives the carbon brush of the columnar contact voltage regulator to move up or down, automatically adjusting the coil turn ratio to ensure a stable output voltage.

As the entry-level model in the SBW series, the SBW-10kVA features a rated capacity of 10kVA and utilizes a three-phase four-wire connection (Phases A, B, and C + Neutral + Ground). It supports dual-frequency operation (50/60Hz), making it compatible with power grid standards across different global regions.

Its independent three-phase regulation capability ensures automatic output balance across phases, effectively handling scenarios involving unbalanced three-phase loads.
