Automatic Voltage Controller is an industrial robot which first monitors items rectifiers the voltage variation round the clock & whenever there is any voltage fluctuation, it rectifiers to the desired level in few seconds. 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 a year/few days in a 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. High Voltage : Voltage Variation % Reduction possible in breakdown of Electrical Equipments with AVC % Power saving possible with AVC Motor Below 10 HP Lighting Load Motor Below 10 HP Lighting Load 380-400 V No Reduction and No AVC required No Power saving and No AVC required 400-420 V 5% 10% 3% 5% 420-440 V 10% 20% 5% 10% 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 Specifications Jindal's Servo is available in a wide range and various models. The standard Three phase models are suitable for balanced & unbalanced supply and loads.     AVC's Application Cement Plant Paper Mills Footwear & Leather Units Flour Mills Tube Mills Distilleries & Beverage Engineering Units Rice Shellers Hospitals Pharmaceutical Units Footwear & Leather Units Rubber Industries Nursing Home Cold Storage Tea Estates Clubs Rolling Mills Food Processing Units High Rise Buildings Textiles Mills Oil and Vanaspati Plant Mall & Multiplex   Comparison of Automatic Voltage Controller Linear Regulator with rolling contact carbon roller assembly Dimmer Regulator sliding contact carbon brush assembly Power Consumption is below 0.5 to 1.5% depending upon the input voltage range. Suitable for 100% duty cycle Life at full load is more than 15 years Five years guarantee 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 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 @40% as per Income Tax Act The Above advantages have been confirmed by the customers by placing repeat orders for their expansion of Plants.

Rectifier is an economical and most efficient method of obtaining DC from AC supply. Jindal manufactures a wide range of rectifiers covering 0-500 Volts and upto 15000 Amps. capacity suitable for Electroplating, Anodising, Hydrogenation and many other Electrochemical processes. The entire manufacturing process is under one roof ensuring 100% quality control at every stage of production. We believe in quality & customers satisfaction. Starting Circuitry Jindal's Rectifiers are designed for 3 phase 50 Hz AC input supply and are available for operations at any voltage between 380 and 440 volts, covering a wide range of voltage fluctuations. It is recommended that the input to the rectifier should be connected through a proper protective device, to provide positive protection to personnel and the system, in the event of maintaining or in case a fault occurs. DC Output Control The function of the variable output controls is to control the voltage or current or its operating range by varying input voltage to the main transformer primary. The DC output voltage variation is achieved steplessly 0-100% by means of an ON LOAD roller type Jindal's make voltage regulator. Salient Feature Jindal's rectifier equipments are wound with electrolytic Prime grade italics to minimise power losses, in comparison to Aluminium italic conductor used by many other manufactures. Our equipments are designed liberally as per capacity and are ideally suitable for marginal over loading conductions. We use verticle Rolling contact type voltage regulator wound with heavy section of copper strips suitable for 100% continuous duty cycle for industrial applications, in comparison to conventional wire wound Regulators used by other manufacturers. The carbon rollers move on both sides of the winding. DIODE : Silicon diodes are tested in house, similar PIV batch and same forward drop diodes are used in the equipment for equal load sharing and reducing the power losses of diodes.  LAMINATION CORE : We use imported CRGO Lamination core which have minimum power losses and results in better efficiency of equipment and saving in energy bill. PAINTS : Epoxy paint is used which is resistant to acidic environment of plating process and enhance the life of the equipment by preventing it from corrosion. METER : We use reputed make AE/RISHAB make DC meters only which are very accurate and durable. CONSTANT VOLTAGE CONTROLLER (CVC) (OPTIONAL) : We offer CVC Electronic attachment with rectifier equipments, which will maintain constant Output Voltage or Current as per setting automatically-irrespective of input voltage variation.
