Pooja is manufacturing Automatic Voltage Controllers (AVC) & Rectifier Equipments for Electroplating/Hydrogenation and also Special Purpose Transformers for industrial applications.

The Stabilizer and Rectifier manufacturing division of POOJA Group is a part of JINDAL Group who are pioneers in this field. The consolidated group is one of the South Asia’s largest power control company with largest client base and service network in the industry.

The group operates from 5 factory complexes which are spread in Himachal Pradesh, Punjab and Haryana.

The group has supplied more than 5000 automatic voltage controller/Rectifiers above 100 KVA capacity to different types of industries/corporate houses throughout India as well as few outside India. As per customers feedback they are working to their full satisfaction and hence getting repeat orders from them. The equipment is the need of every power consumer.

The Basic purpose of AVC is to maintain the desired voltage and to reduce the breakdown of electrical equipments due to low/high voltage. Power saving Reduction in MDI and improvement of P.F. will be added advantages at high voltage.
Capital & Interest cost is just 1.5% per month.

Saving by reduction in breakdown of electrical equipment and energy saving shall be 4-8 times of capital & interest cost.
Voltage variation is common phenomenon. The input voltage is generally low during day time and high during night hours.
Apart from above, few months in year/few days in month/few hours in a day the voltage is either low or high due to the following reasons:
  • Holidays
  • Peak Hours
  • Rain Days
  • Agricultural Load
  • Weather Conditions etc
Therefore for smooth function it is suggested to install AVC with +- 15% or 20% input voltage variation range i.e. 340-460 volts or 320-480 model.

In India all electrical equipments are designed for 230/400 volts single/three phase. After installation of Automatic Voltage Controller you will have number of the following Advantages:-

Suggestion : It is suggested to note down hourly input voltage by installing digital voltmeter at the security gate of your factory premises for a week.
Check : Failure rate of Electrical Equipments such as Bulbs, Tubes, Chokes, Contactor Coil & Electronic Equipments etc.

440-460 V 20% 40% 7% 20%
460-480 V 40% 80% 10% 30%
Low Voltage
At low voltage you will not be able to operate your machines at rated capacity resulting in lower production.
You need to run the machines on DG set. The power cost of DG set is three times as compared to charge by electricity board.
Advantages of AVC
  • Reduction in Breakdown of Electrical Equipments
  • Reduction in MDI
  • Energy Saving
  • Improvement in Power Factor
  • Uniform Quality of End Product
  • 80% Depreciation as per Income Tax Act

Pooja’s Servo is available in a wide range and various models. The standard Three phase models are suitable for balanced & unbalanced supply and loads.

  • Life at full load is more than 15 years

  • Five years guarantee

  • Economical for continuous/industrial load above 100 KVA

  • Power Consumption is above 2 to 7% depending upon the input voltage range.

  • Suitable for less than 50% duty cycle

  • Life at full load is less than 3 years

  • One Year Guarantee

  • Suitable for commercial/residential load below 50KVA

Cost Per Month
It is such a fine equipment, which first monitors the voltage variation around the clock then rectifiers the same if required instantaneously & cost just 1.5% per month of capital & interest and will save 4-8 times as explained here under:
For Example :
The cost of AVC            Rs. 10,00,000/-
(Including Installation material, Expenses & Taxes etc.)

Life of AVC Approx. 10 Years
Cost Per Month for 10 Years (Rs. 10,00,000 / 120 months)
Rs. 8,333/-
Interest P.M. on Reducing Basis @ 12% on Rs. 10,00,000/- Rs. 5,000/-
  Total Rs. 13,333/-
Pay Back
It is a equipment, which pays back its cost within 1-2 years. If we try to rectify voltage variation manually it might be rectified but cannot be monitor always.

With the expenses of Rs. 13,333/- per month, you will be able to achieve savings of more than Rs. 55,000/1,10,000/- per month depending upon the input voltage variation and working hours of the plant due to the following advantages:

  • Reduction in breakdown of electrical equipments up to 80%.
  • Energy Saving up to 5%.
  • Improvement in power factor and reduction in MDI.
  • Uniform quality of end product.
  • Better efficiency in plant due to lesser Breakdown.
  • Depreciation @80% as per Income Tax Act.
The Above advantages have been confirmed by the customers by placing repeat orders for their expansion of Plants.
