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. The three phase servo voltage stabilizer helps in 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 and the best product which saves from such issues is the 3 phase servo controlled voltage stabilizer.
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 the 3 phase servo controlled voltage stabilizer and the 3 phase servo stabilizer for home.
Three phase servo voltage stabilizer are automatic line Voltage corrector using synchronous motor in close loop control. The stabilizer employ continuously variable auto transformer, buck-boost transformer, AC synchronous motor, state of the art IC closed loop control system with all protection, metering, indication and control system to give desired output voltage within the specified limits for a range of input voltages. Provision for manual correction of voltage can also be provided.
