Product Description

Having immense experience of more than three decades, we have been engaged in manufacturing, exporting and supplying Voltage Stabilizers. The offered stabilizers are highly demanded in industrial and commercial sector to compensate voltage fluctuations in main power. These stabilizers are manufactured using quality-approved components and cutting-edge techniques in tandem with industry norms. Moreover, the provided Voltage Stabilizers can be availed from us in several technical specifications at reasonable prices.

Voltage Stabilizer


Fluctuations in the voltage is a constant feature of Electricity supply we get. Constant fluctuation of a voltage leads to frequent breakdown and higher rejection in end product. We know that 90% of industrial load is of motor. It draws high current at high & low voltage. This higher current produce higher losses in electrical motors. These losses in motor increase the losses in Cables, Switches, Transformers and other associated equipments.

This higher current effects the electrical motor (particularly smaller capacity motor up to 7.5 H.P)in 3 ways
Higher current produce higher loss in electrical motor which cause premature failure of winding.
These higher losses of electric motor also increase the losses of cable, switches, transformer &other associated equipment.


For smooth continuous operation of motor, over load relay are usually set at 20% higher selling.

With the installation of the stabilizer & maintains 390/400 volt, the motor will operate smoothly drawing 15-20% lesser current & correspondingly the relay setting can be reduced by 15-20%.



The Buck/Boost and Regulator Transformer winding are built from paper covered electrolytic copper strip or enamelled copper conductor (Dried in oven). The core is built of high grade cold rolled grain oriented silicon lamination (CRGO) to minimise iron losses. All components of equipment mounted on a framework of M.S. housing are fitted with cooling pips to provide natural cooling.

We provide a vertical Rolling Contact types voltage regulator with having sections and paper covered copper strip and fitted with carbon roller assembly which offer higher reliability than ordinary carbon brushes. It is also built with high quality meter switches and indicators.

It is designed for 30-35 Degree Centigrade above ambient suitable for any kind of ambient temperature condition. Oil which is used as a coolant is of IS: 335 standards being used & it is properly filtered before topping.

Standard Fitting & Accessories:

-Rating Plate
-Lifting Lug
-Drain valve
-Oil Level
-Oil Filling hole and plate
-Control MCB's [1.0 Amp for motor load & 0.5 Amp for voltmeter & indicators]

General Specification:

Bharti's Automatic Servo Stabilizer are available in wide range and various models. The standard three phase models are suitable for balanced and unbalanced supply and loads. The standard model confirm the following specifications are as follow:

Automatic Voltage Regulator - Regulator with Carbon
Regulator with Carbon
Roller Assembly

Input Voltage


300-460V 320-460V 340-460V 360-460V.
Efficiency : Better than 99%.
Output Voltage : 400V, +/- 1%, Phase, 50HZ.
Ambient : 0-35C max relative humidity upto 90%
Environment : Designed for Indoor tropical use
Wave from distortion : Virtually Nil.
Duty Cycle : 100% Continous.
Correction Rate : 8-10V/Sec. (Upto-500KVA).
Mounting : On Uni-directional wheels.
Cooling : Air Cooled/Natural Oil Cooled.

NOTE: Different Non-Standard input & output ranges are also available against specific requirement.


Comparison between Bharti s make & Conventional make Automatic Voltage Regulator:
Bharti make roller type Regulator Conventional make with carbon brush Regulator
Suitable for 100% continuous duty cycle
Power consumption is 0.5 to 1.5% depending upon the model & input voltage variation.
Life at full load is 15-20 years
Negligible losses at full Buck/Boost conditions.
5 years unconditional guarantee in india.
As losses are less, heat generated is less. The size of stabilizer is very compact. Quantity of oil is less.
Suitable only for partial load 50-60%
Power consumption is 2-7%
Max. life is 3-5 years at full load
Max-losses in full Buck/Boost condition
Normal guarantee/warrantee for one year
Heat generated is more. Size is bulky. Quantity of oil is more.

More Uses:

1. In residential area, we usually face unbalanced input voltage, in that case Automatic Voltage Controller is used to Overcomethis problem. This unbalanced voltage usually causes the failure or damage of motors, machines, electronic items used in houses, tubes, bulbs, fans etc. If you find input voltage is above 230 Volt single phase/400Volt three phase even for few hours a days, then you definitely require a stabilizer.

2. Industries which have installed OLTC with transformer also require Stabilizer because with help of Stabilizer, we don't have to change the tapping of OLTC frequently. However range of Stabilizer can be kept low where OLTC is installed
