Product Specification for Servo Controlled Automatic Voltage Like Hospitals, Laboratories, various life saving & testing equipments, pharmaceuticals, Research Institute Product Information Sakthi Servo Voltage Stablizer essentially employs a Solid-State circuit, which controls the Servo Motor. The motor is mechanically coupled to the arm of a continuously variable Auto Transformer (Variac) that feeds to the primary of a series control Buck-Boost transformer. The stabilizer output voltage is compared with the reference voltage and the resultant error signal controls the Servo Motor providing true proportional control systems rather than On/off circuits Widely accepted design to suit various conditions. All the phase/s are independently sensed & corrected. Suitable for both balanced/ unbalanced loading & incoming voltage.
