Static Voltage Regulators & Servo Voltage Stabilizer

We offer reliable corrections against the voltage fluctuations to the valuable devices connected to raw electricity SVR uses the advanced micro controller based digital controller to control the high speed MOSFET & IGBTs for the basic voltage correction rate & speed correction also. The complete absence of moving parts demand zero maintenance, enhance reliability thereby further reducing service trips & network down time man days. These true RMS based static stabilizers are specially design as per requirements & specifications of user.

Servo Voltage Stabilizers

Indotech introduces INDO SERVOSTABILIZER. This 3 phase Digital servo Voltage Stabilizers are specially designed for supplying a controlled and continuous 3 phase AC power supply in situation of fluctuating power. The standard models of these Indo Servo stabilizers are ideal for balance & unbalanced type3 phase supply load. These are designed using Micro-controller based control circuits that ensure minimum break down during the operation.
