Industrial Voltage Stabilizers

Rolling Contact Type Voltage Controller holds its potential for units having either L.T. Supply (above 80 Kva) or H.T. Supply (upto 5000 Kva), These are designed for Balance Supply and Unbalance Load as well as Unbalance Supply and Unbalance Load. Voltage Input Range depends upon the incoming conditions at individual sites. These products is suitable for both Indoor and Outdoor Installation.

These controllers are used to produce a steady output voltage despite fluctuations of input voltage. Our Rolling Type Voltage Controllers posses High End Quality raw material to maintain lowest of unwanted Losses (Load & No-Load Losses). Superiority of the product can be judged by the fact that we are offering "5 Years Unconditional Guarantee" on our product.


Table below gives approximate quantitative advantages of automatic voltage controller at various fluctuation levels:

We are involved in manufacturing a wide range of HT-Automatic Voltage Regulators. These regulators have helical coils mounted on a conventional laminated core. Carbon rollers are assembled on a fiber glass carrier board and are traverse to the length of the coil track. The rollers are connected to the electric output terminals. Nearby the regulating coil, a number of compensating winding are connected in parallel, which are short circuited to reduce the effect of core-flux fringing. It also keeps the reactance of the regulator constant at any position of the rolling contact.

HT-AVR are used to get stable input voltage, irrespective of the voltage received from electricity authorities. Additionally, these stabilizers also prevent the transformer and other electrical equipment from getting overloaded. AVR take care of wide voltage variation ranges continuously and in on load conditions.

The variations of more than ± 1% of the rated output voltage are sensed through solid state relay. This relay operates on 230 V, 1Ø supply. It sends signals to the controlling servo voltage stabilizers motor, which drives the roller mechanism in a direction to bring voltage to the rated output voltage.

Advantages

• Energy saving between 5% to 10%. High efficiency (above 98%) & minimum load losses.
• Increase in the productivity by reducing the breakdown period of the machines.
• On Load stepless voltage variation.
• Constant Voltage throughout the plant causing reduction in maintenance cost of the equipment.
• Low replacement cost.
• Long Service life.

In Most Industries a minor voltage fluctuation can cause malfunction in equipment or break down consequently and can hamper production. No One likes to risk the life of Costlier and sensitive electronic & electrical equipment, Our Variac Type Digital Servo Stabilizer Equipped with latest Digital Micro Processors Controllers, have been designed to give a constant output voltage with stability of +/-1%. Output voltage stability of our Servo Stabilizer allows the optimum drawing of the current and as such no extra power is consumed as low as well as high voltage. Our Servo Stabilizers posses High End Quality raw material to maintain Lowest of Unwanted Losses (Load & No-Load Losses) and consequently maintaining high efficiency and reducing overall MDI.
