In laboratories and Industries where precision supply voltage is essential to avoid damage in costly equipments and instruments, use of servo controlled voltage stablizer are recommended. This type of voltage stablizer provides desired output voltage, either in single phase or three phase with a minimum of variation i.e. ±1% with an wide input range starting from 90V-265V in the lower side & 220V-290V on the higher side for single phase stabilizer & 160V-500V in the lower side and 380V-500V on the higher side for 3Phase variety as per customers specification.
A Servo Controlled Voltage Stabilizer essentially consists of a variable auto transformer (variac) coupled with a servo motor, a buck-boost transformer and an electronic controller. A sample output is taken and compared with a reference standard. The difference is called Error signal which is used to drive the servo motor for output voltage correction.
Stabilizers for balance load and supply systems can be used when variations in input supply voltage (phase to phase or phase to neutral) in all three phase are almost equal. In this Stabilizer a single 3 phase variac coupled with one drive motor is used for voltage correction. Output of any one phase of the three phase is selected and monitored to actuate the drive motor.
Stabilizers for unbalanced load and supply systems can be used where the three phase voltages vary in an unbalanced manner. These Stabilizers have three nos. single phase variacs individually coupled with drive motors. Each drive motor along with electronic controller is entrusted to take care of one phase to neutral voltage and load variation independently. In other words these stablizers are a combination of three nos. Single Phase Stabilizers connected in STAR configuration.
Fiji Electronics Pvt. Ltd. manufactures Servo Controlled AC Voltage Stabilizer of various capacities starting from 0.5 KVA to 20KVA in single phase and 3KVA to 1000 KVA in Three Phase.

Wide fluctuation of main supply voltages is harmful for T.V., Refrigerators, Vacuum Cleaner, Air Conditioner etc. Fiji Electronics Pvt. Ltd. have designed voltage stablizer which gives an output which normally varies between 200V – 240V±1% which is considered safe limits of such equipments and appliances.
There are two types of Voltage Stabilizers suitable for use with domestic appliances (1) Manual Voltage Stabilizers, (2) Automatic Voltage Stabilizer.
1.Manual Voltage Stabilizer consist of a Single Phase Auto Transformer with multiple taps. The taps are selected with the help of a Rotary Switch of appropriate rating to give the desired output with a wide variation of input voltage i.e. from 50V-280V.
2.An Automatic voltage stablizer also uses an auto transformer with several tappings and a control circuit. The solid state electronic controller senses the label of input supply and sends the required command signal to actuate electro magnetic relays to select a particular transformer tapping thus manufacturing the output voltage within the safe limit.
FIJI has got both the stablizers of various capacities for domestic use starting from a Minimum of 100VA to Maximum of 20KVA.
