Product Overview

Why you need a Servo Voltage Stabilizer?

It is seen that In spite of best efforts by various Electricity Boards / Supply undertakings the voltage at consumer’s end is never constant. The reason being diverse loading duties arising in transmissions and distribution network. During the day time when the load requirements is more the voltage remains quite low and during night it goes up than the normal. As a result of these never ending voltage fluctuations there is frequent Tripping / Breakdown of the systems / machines and precious equipment’s resulting into low production.

Our range of Servo Voltage Stabilizer can overcome and control these voltage fluctuations & can provide you with the desired constant output voltages. Our every Automatic Voltage Regulator rolled out of the factory undergoes strict and rigid inspection and testing.

Our Automatic Voltage Controller are duly Tested & Approved by Govt. lab Electronic Test & Development Center (ETDC) & are manufactured As per IS 9815 Standards. (as per Indian Government)

Our Servo Voltage Stabilizer are available in a vast choice of Input and Output Voltage range suitable for various applications in industries, institutions and residences etc. having indigenous, imported sophisticated machines / instrument / gadgets etc.

Rating Available: 1 KVA to 1500 KVA (Special ranges also available on request)

 Servo Stabilizer is not just a voltage fixing system, but a completely reliable energy device that is advantageous over the traditional relay based stabilizer. We have quite a number of benefits of using Servo:

1. High voltage correction accuracy with output of ±1 voltage correction.

2. Switch less system to adjust fluctuating voltage at desired levels.

3. High load capacity that supports up to 5000 KVA or above.

4. Voltage is based on step less correction.

5. Perfect stabilization for hospitals best for intricate machineries like X-ray machines, CAT scans, radiation and diagnostic equipments.

6. Wide functioning area from schools, offices, homes and industries.

7. Oil cooled and air cooled transformers that fit your budget.

Eventually, Servo stands the winner because of its unmatched performance and longer life features

Transformers & Variacs  Are wound with electrolyte grade copper of 99.9% purity, Low loss CRGO Lamination is used to increased over all efficiency, this reduced Energy losses and hence Saves Electricity.
Earthing Provided through two bolts & Nuts
High Voltage With stands 2. 5KV for Power Transformer
High Voltage Better than 5m ohms because of wound components being baked in the oven at 110ºc after vacuum Impregnation
WINDINGS Coils are wound with paper covered electrolytic grade copper strip or synthetic enamelled copper conductors. Cooling ducts are provided to keep the hot spot temperature as low as possible. Coils are dried in electric ovens. Rigid connection support and coil clamping is provided to ensure high short circuit strength.
TANK AND PAINT The tank of Servo Voltage Stabilizer is made of M.S. steel sheets. All the external surfaces are given a primary coat of epoxy and finishing coat of epoxy paint for better life and leak proof. All our tanks are power coated for shelf life of 20 – 25 years.
OIL Oil tested for resistivity, dielectric and acidic characteristic conforming to IS 335, transformer oil is an important part of Servo Voltage Stabilizer which provides cooling to the critical components housed inside the tank, so we always make sure that the quality of the transformer oil is far better.
DUTY CYCLE Conventional type stabilizers are suitable for 50-60% load on continuous duty cycle. Servo Voltage Stabilizers are heavy duty and industries friendly and are suitable for 99% load continuous duty cycle.
Optional Feature 
(Which can be incorporated for extra cost)
: High and low Voltage cut off system 
: Over Load and Short Circuit Protection 
: Phase sequence change protection
