- High efficiency & Fast response.
- Wide input voltage range & Audiable alarm for trip conditions.
- 99.99% failure proof control circuit.
- No over under, shoots and hunting.
- Built in bypass switch upto 100 Kva.
- Less active component avoids failure ratings.
- Special electronic circuit to operate on gensets.
- No effect of power factor and frequency variations.
- Single PCB for three phase sensing and correction.
- Voltage at speed related to rate of fluctuations and avoids oscillations & hunting in DC motor drive.
- Variable speed high torque dc servo motor proportionally controls corrections.
- Rugged and smooth ac motor drive control through optoisolator circuit which is Highly reliable.
- Separate isolated PCB for triac switching for motor.
- Wide input voltage range & Audiable alarm for trip conditions.
- All components sourced from reputed manufacturers, confirm to IS/BS/VDU Standards
- All raw material inspection as per internal components manual
- Individual assemblies tested on full load at 55 deg C in oven for 48 hours to minimize failure
- Final equipment tested for accelerated life test to identify and replace any weak links.
- Input and Output Low Voltage protections.
- Input and Output High Voltage protections.
- Phase rotation/single phasing preventer.
- Input protection using HRC fuse.
