Automatic Voltage Controller/Servo Controlled Voltage Stabilizer

Description of Servo Controlled Automatic Voltage Controller:

K.s. Power's Servo Stabilizer is manufactured as per standard quality rules and primarily consists of the following:

1. Linear Plus/Minus Type Vertical Rolling Contact Voltage Regulator

In our regulator we are using heavy section of electrolytic grade rectangular copper trip instead of copper wire to minimize the losses & increase the efficiency of equipment. We are also using self lubricating Carbon Roller Assemblies instead of ordinary Carbon Brushes which offers more reliability and trouble free performance of the equipment.

2. Double Wound Buck/Boost Type Series Transformers

In our Buck/Boost Transformer we are using CRGO lamination to minimize iron and coils of Buck/Boost Transformer are wound with heavy section of multi strips electrolytic copper to minimize copper losses for getting better efficiency of the equipment.

3. Electronic Control Circuit and Meter Panel

K.S. Power's Automatic Voltage Controller consists of very simple electronic control circuit for monitoring and controlling voltage, repair and maintenance of which is very easy. The regulator and Buck/Boost transformer are oil cooled, housed in same or separate sheet steel tanks. Radiators are provided for effective cooling. The coils of voltage regulator & Buck/Boost Transformers are vacuum impregnated and oven dried as per IS.
