PEC is an iso 9001:2015, NSIC-CRISIL, Dun Bradstreet (862376458), IEC, FGI, DIC, EEPC & EXIM registered company. PEC’s Automatic Voltage Controllers/ Rectifiers have a robust design and give trouble-free service. we provide you the finest products designed and engineered by people & professionals who have experience and expertise in each sphere of activity right from testing, quality control, manufacturing & designing of these products for the last 35 years. we have with us the state-of-the-art infrastructure with excellent and advanced capabilities to manufacture world-class automatic voltage controller with quality standards.   TECHNOLOGY: Voltage Regulator is the essential and main functional part of AVC equipment. our voltage regulators are liner-type regulators with rolling contact carbon rollers. we use heavy-duty carbon rollers which do not need any replacement for at least 20-25 years.   COMMITMENT: we have a commitment to provide a FIVE-YEAR GUARANTEE for all the equipment supplied by us. After-sales service is the backbone of our organisation.   We have developed and installed industrial Automatic Voltage Controller throughout India which are suitable for 100% continuous duty cycle supplied up to 5000 kva which have more than 99.5% efficiency.   ADVANTAGES OF INSTALLING AVC : Customer will certainly have the following advantages in case they are getting higher input voltage i.e. more than 230 volts single phase/400 volts three phase.   • Reduction in breakdown of electrical equipment • Energy saving 5-10 % on motor load and 15-25% on lighting load. • Reduction in mdi by 10-15%. • Improvement in power factor. • Depreciation allowance @80% as per income tax act. • Uniform quality of end products.   Automatic Voltage Controller primarily consists of the following   1.       Linear, Plus / Minus Type Vertical Rolling Contact Voltage Regulator   In our voltage regulator, we are using heavy section of electrolytic grade rectangular copper strip instead of copper wire to minimize the losses & increase the efficiency of equipment. We are also using self lubricating carbon roller assemblies instead of ordinary carbon brushes which offer more reliability and trouble free performance of the equipment.   2.     Double wound buck / boost type series transformer   In our buck / boost transformer we are using crgo lamination to minimize iron losses. Coils of buck / boost transformer are wound with heavy section of multi strips electrolytic copper to minimize copper losses for getting better efficiency of the equipment.   3. Electronic Control Circuit and Meter Panel   Automatic Voltage Controller consists of very simple electronic control voltage circuit for monitoring and controlling voltage, repair & maintenance of which is very easy. The regulator and buck / boost transformer are oil cooled, housed in same or separate sheet steel tanks. Radiators are provided for effective cooling. The coils of the voltage regulator & buck/boost transformers are vacuum-impregnated and oven dried as per IS.   SPECIAL FEATURES   Special Features of PEC Make Automatic Voltage Controller:    EFFICIENCY   The efficiency of PEC make Automatic Voltage Controller is more than 98-99% in comparison to 93-97% of conventional make available in the market depending upon the input voltage range. Thus, a 500 kva conventional type stabilizer or conventional servo voltage stabilizers will consume additional power itself minimum rs. 80,000 p.a. (even when running at 60% load and 20 hours a day) on account of its lower efficiency by 2%.   BETTER LIFE   The Life Of Make Servo Voltage Stabilizers Is More Than 10/15 Years At Full Load In Comparison To 2/3 Years Of Conventional Make.   DUTY CYCLE   Conventional Type Stabilizers are suitable for 30-40% load on continuous duty cycle. Our automatic voltage stabilizers are heavy duty & industrial type and are suitable for 100% load continuous duty cycle. For running load of 200 kva, generally 400 kva / 500 kva conventiona

The output DC voltage variation is step less by means of ON LOAD motorised regulator. We use vertical ROLLING CONTACT TYPE voltage regulator, wound with heavy section of copper strip, suitable for 100% continuous duty cycle. The life of these regulators is more than 25 years and have 4 - 5 % better efficiency in comparison to conventional dimmerstat type regulators. - Please note that Rectifiers manufactured by us, we are using plus/minus type (+ 254 Volts OR + 440 Volts) Voltage regulator in "Q" connection - which means that the capacity of voltage regulator required in our Rectifier winding design is 50% in Star connected (+ 254 Volts) model and 30% in Delta connected (+440 Volts) than straight type (0-440 Volts) voltage regulator used by conventional design rectifier winding. - With Plus/Minus type voltage regulator used in our rectifier design, the capacity of Voltage Regulator used remains the same, but the brush current of the Regulator reduces and the reliability of regulator increases. This results in considerable saving in overall power losses of our Rectifier equipment.
