Servo Voltage Controller


Servo Voltage Controller

  • The Modern's Linear Voltage Regulating Transformer has been specially designed to meet a wide variety of heavy-duty industrial applications. Globally, these have become an established method of control, wherever continuously variable on-load control of voltage & power is needed. These regulators are wound with heavy section of copper strip and are suitable for 100% continuous duty cycle. They have an economic life of about 15-20 years at full load and require negligible maintenance throughout their life.
  • Modern's Voltage Regulating Units combine fixed ratio transformers with regulating transformers to extend their rating, versatility and applications. MODERN'S AVC primarily consists of following key components housed in the same tank.
  • Liner +/— Vertial Rolling Contact type On-Load Voltage Regulator
  • Double Wound Buck / Boost Transformer
  • Control Panel with Microprocessor based control module.


Modern Electrofab's AVC resolves 99% of voltage problems automatically, and ensures steady voltage supply round the clock. Some key advantages of installing and AVC are :

  • Up to 80% Reduction in Breakdown of Electrical Equipment
  • Up to 30% Saving in Electricity Costs.


The table below gives approx. quantitative advantages of AVC at various voltage fluctuation levels  :

  • Uniform Quality of End Product.
  • Improvement in Power Factor.
  • 80% Depreciation as per Income Tax Act. in India (Being
  • and energy saving device)

    • Upto 30 KVA to 2500 KVA (Three Phase)
  • HT Automatic Voltage Stabilizer Upto 500 KVA to 5000 KVA
  • Silicon Power Rectifier - Linear Type :
    • a) Electro Plating Rectifier
    • b) Hydrozen Rectifier

 

  • Let's draw an analogy of a human body, Our body needs to maintain a constant temperature of 98.40F to work effectively. Even a minor increase of decrease in body temperature can reduce our efficiency and can lead to further deterioration of one or more body parts.
  • Similarly, most electrical equipments require a constant voltage supply of 400V to last longer & run efficiently. Electric motors draw considerably high current at High/Low voltage, causing excessive power losses and resulting in their premature failure. Similarly Bulbs / Tubes / Luminaires could consume up to 40% more power at high voltage and may last for a mere 10% of their normal life.
  • The growing use of electrical and electronic equipments, requiring a near constant voltage supply for efficient operation, makes line voltage regulation increasing necessary and finer limits, operation.
  • Voltage variations can play havoc with electronic systems and even bring the whole plant to a grinding halt. Even though you may currently not be experiencing the negative effects of voltage variations, it doesn't imply that your unit is free from that problem! Your supply may be full of variations, but none has yet been severe enough to trigger a shut down. Your electrical gadgets may be exposed to a significant risk, whre a small increase in severity of the voltage variations could cause crippling losses.
  • Frequent breakdowns / faults in motors, bulbs, lamps, machinery, electronic cards, etc.
  • High electricity consumption Loss of production
  • Quality rejections
  • High Diesel costs due to switching to costlier D. G. power
  • Loss of data, security failure, inaccurate information, etc.
  • Voltage Stabilizers have proven to be an efficient answer to prevent from aforesaid potential damages, and to ensure continuity and quality of production.
