Automatic Voltage Stabilizers
L.T. Automatic Voltage Stabilizers hold its potential for units having either L.T. Supply or Low capacity H.T. Connectin. The same can be manufactured for Balanced Supply for unbalanced Loads or Unbalanced Supply for Unbalanced Loads. The range of input Supply for which the stabilizer is designed depends upon the voltage condition at the supply point. How Some Standard ranges for L.T. Stabilizer are as under :

Servo Voltage Stabilizer is commonly observed that, AC main supply is never 230 Volt or 415 Volt, but varies from 150 Volt - 300 volt and 300 Volt - 500 Volt. The difficulties caused by them are well known, such as Over Load Condition, Line Losses, Poor Power Factor and several other reasons. Generally constant voltage which is required to load is never constant, but in fluctuation manner. It is observed that during the daytime, the voltage is quiet low and during the night the Voltage is high then the normal.
This fluctuation in supply system results frequent breakdown, low production and also loss of energy. The performance of any electrical equipment is optimum at its rated voltage. Both over / under voltages are harmful for the system. The under voltage reduces efficiency whereas the over voltage shortens the life.
The power agencies insist the consumer to fix the capacitor to improve power factor to get better results in power saving. But Voltage is far more important factor to save the power loss.
In case of very Low / High voltages, the telecom systems are powered by DG sets. Our Line Conditioner Unit meets the requirement of input voltage variation from 110V - 280V (Single phase) and 300V - 500V (Three phase). 240V - 500V is also available on demand.
In India, there are large voltage variations in the mains power supply. To overcome this problem, we are offering Line Conditioner Unit.
