Features of Servo Stabilizer
The highly skilled engineers and prominent management professional deals with the manufacturing of the best servo voltage stabilizer. The deep and consistent R&D in the field of electrical energy and voltage fluctuation makes the product safe, reliable, and accurate to work. The components selected in manufacturing ensures fast and high correction ratio to be maintained against voltage fluctuation through the operation. These dedications have ensured trouble free and efficient operation for both small size equipment and heavy electrical equipment. The whole unit is enclosed in a sheet metal cabinet, with full ventilation, which is sprayed with paints having lacquer finish. The assembly makes the servo voltage stabilizer a very rigged device, with sleek design & look, free from vulnerability to any corrosion ensuring long product life cycle for the stabilizer.

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.
EarthingProvided through two bolts & Nuts
WINDINGSCoils 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 PAINTThe 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.
OILOil 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 CYCLEConventional 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.
