Automatic Servo Voltage Stabilizer.
All electrically operated equipments are desired for a certain supply voltage. If they operate on supply voltage lower than or in excess of its rated volts the end result in economic loss. There are many ways in which the fluctuation can be brought under control, at the consumer’s end. The Saudamni make servo voltage stabilizers are the best because.

1. They have large short time over load capacity.
2. Their losses are negligible whether at no load or full load.
3. They are unaffected by load power factor.
4. They do not introduce wave from distortion.
5. They are simple in design and easy to understand.
6. They do not any consumable item.
7. Their size is small for their load handling capacity.
8. High speed of voltage correction. 

The Salient Features

1. Voltmeter with selector switch provided to show Input/Output voltage with ON/OFF Switch to read Input & Output voltage.
2. Alarm lamp switch Light up when the input voltage exceeds the limits of specified range.
3. A switch to change from automatic voltage correcting action to manual.
4. Fully automatic to solid-state control system to keep output level with in + 1% accuracy.
5. Potentiometer to set desire output voltage from 380 Volts to 420 Volts in three phase unit and 200-240 Volts in single phase units.
6. Push Button switch marked RAISE or LOWER to change the output voltage in manual position.
7. Output indicating lamps to show supply “ON”.
8. Type SVS – 100 and 300 consist of one electronic sensing circuit and one servo motor whether the SVS –303 model consist of 3 sensing units and three servo motor to control each phase individually.
9. The unit above 200 KVA rating will be supplied in two parts one is the regulator transformer & other in power transformer.
10. In Oil Cooled Model, Oil level Indicator, Oil Filling & Oil Facilities provided with each unit.
11. Oil Cooled unit supplied without first Filling of oil.

The following additional features can be provided against specific enquiries at an extra cost.

1. Under voltage and over voltage cut off.
2. M. C. B. /M. C. C. B. protection on the input/output.
3. Digital Voltmeters, Ammeters and Frequency meters.
4. Single phasing preventer to trip the supply in case of phase failure.
5. Surge & Spike Suppressor

Specifications
