| We manufacture high efficiency servo controlled voltage stabilizers which are suitable for weather conditions in Indian subcontinent. It works effectively under voltage fluctuations and helps in obtaining one output. It is fast acting, and any variation in the supply, frequency, load and P.F. does not have effect on the output voltage setting. The stabilizer is provided with a fully solid state voltage sensing relay using professional grade components. The important components of the stabilizer are made under strict quality control.

| Specifications Standard models SEI Voltage stabilizers are made to following specifications :
Non standard models are made to customer's requirement to cater any other input voltage range / Output voltage / frequency / capacity etc. 3 Phase models with single voltage sensing relay and single drive motor are suitable for fairly balanced supply voltage and load. To over come unbalanced voltage and load conditions, 3 Nos. 1 phase units mounted in a single cabinet and connected in star, are recommended. Built in Features
Operation The Voltage Stabilizer works on a simple principle of adding or a subtracting a voltage to the supply voltage in appropriate quantity to correct it to the required level. This voltage to be added or subtracted is obtained from the mains itself, using a VARIPaC a continuously variable voltage auto Transformer, driven by a servo motor under the control of voltage sensing relay. This relay senses the output voltage continuously, compares with a highly stable reference and directs the drive motor to correct the output voltage to the set level. Salient Features
