Servo voltage stabilizers for loads that cannot trip
Motor-driven regulation built in our Chinhat workshop — sized after survey for single-phase and three-phase industrial duty across Uttar Pradesh.
Stable output when the line will not stay still
A servo stabilizer senses input voltage changes and drives a Buck-Boost transformer through an AC synchronous motor — with control card, dimmer, and comparator logic — so output stays within a tight band for sensitive and industrial loads.
- Oil-cooled builds up to high industrial kVA
- Air-cooled options for lighter and compact duty
- IP55-compliant enclosures for harsh electrical rooms
- Relay-based AVR variants where the application fits
Why sites need a servo stabilizer
Voltage swings shorten motor life, trip CNC and medical equipment, and interrupt production shifts.
Cut nuisance downtime
Reduce trips and restarts caused by sag, swell, and unbalanced feeders.
Match phase and capacity
Single-phase 1–20 kVA for lighter loads; three-phase industrial capacity for plant boards.
Cool for the room
Oil-cooled or air-cooled builds selected for ambient, continuous load, and enclosure rating.
