Advanced MCU with true RMS sensing

Digital MCU-based control with true RMS sensing delivers accurate voltage regulation even under non-linear and adverse waveform conditions typical in industrial and commercial environments.

Firmware-controlled buck-boost transformer (> 97% efficiency)

A firmware-optimised buck-boost transformer achieves greater than 97% AC-AC efficiency, reducing energy losses and delivering measurable cost savings over the operating life of the unit.

Fast correction speed (50 V/sec, response < 20 ms)

A correction speed of 50 V/sec (Ph-Ph) and response time of less than 20 ms protect sensitive equipment from the damaging effects of rapid voltage swings.

Wide three-phase input voltage range

Operates across a Normal range of 340–480 V and a Wide range of 310–480 V, covering the full spectrum of Indian three-phase grid conditions.

Comprehensive three-phase protection suite

Provides protection against phase failure, single phase prevention and cut-off, neutral failure, frequency cut-off (low/high), surge, input/output over- and under-voltage, overload, short circuit, carbon brush failure and phase reversal trip.

2-line LCD display with per-phase metering

Displays line-line and line-neutral input/output voltages per phase, load current, output frequency, fault annunciation and events for thorough on-site monitoring.
