Salient Features
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.
High Reliability
High reliability due to digital and controlling using micro controllerAll components sourcedfrom reputed manufacturers, confirm to IS/BS/VDU standardsAll raw material inspection as per internal components manualIndividual assemblies tested on full load at 55 deg c in oven for 48 hours to minimize failureFinal equipment tested for accelerated life test to identify and replace any weak links.
Protections
Input and Output Low Voltage protections.Input and Output High Voltage protections.Phase rotation/single phasing preventer.Input protection using HRC fuse.Control circuit protection using fast blow fuse.Electronic overload protection.
