Servo Stabilizers - Servo Power Solution

Three Phase Oil Cooled Servo Stabilizer

Project Description

Provides perfectly stable output even under severe conditions of unbalanced voltage conditions. Ideal to protect the electrical and electronic equipments from high and low voltage.

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 30KVA.
For above 30KVA we are using Onload change overs.
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.

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.
Control circuit protection using fast blow fuse.
Electronic overload protection.
Earth fault protection.
We are using Surge Protection Device and Surge Arrestors.
