Voltage surges and sags are a leading cause of electronic equipment disruptions and failures. The Three Phase 10kVA – 1mVA “Series 700A” is a solid-state, automatic power conditioning voltage regulator that protects your equipment by guarding against these types of power anomalies, as well as longer duration over- and under-voltage conditions. The “Series 700A” precisely regulates line voltage to within ±3% of nominal in one cycle, and that voltage regulation is maintained during extended brownouts.
