Suvik Electronics Private Limited designs and manufactures Single-Phase Servo Controlled Voltage Regulators. Suvik Electronics Private Limited is an ISO 9001: 2000 and certified company. The Single-Phase Servo Controlled Voltage Regulators are an effective solution to the problem of voltage fluctuation. They are designed to give a stabilized output within 1 percent of the preset voltage level adjustable between 220V and 240V from the front panel. These servo regulators contain a motorized auto-transformer which bucks or boosts input supply to give a stabilized output. A solid state control circuit ensures error free operation. The output waveform is completely distortion free.
