Type SE – 15-1

Single Phase Servo-Controlled Voltage Stabilizer. Suitable for use with single phase equipment.

Type SE – 15-3U

Three-phase Servo-Controlled Voltage Stabilizer. Recommended for use with unbalanced input supply voltage and/or unbalanced loads.

It consists of three single phase units connected in star. Each unit has a motorized single phase variac and a series transformer. Voltage of each phase is independently sensed and corrected to the desired value.

These units are, therefore, suitable for use with unbalanced input supply voltages and unbalanced loads.

Type SE – 15-3B

Three-phase Servo-Controlled Voltage Stabilizer. Recommended for use where 3-phase input supply and load are balanced i.e. all line voltages and currents are same.

This regulator employs a three phase variable transformer (3 nos. of single phase variable transformers mechanically coupled) driven by a single servo motor and three-phase series transformers. The Output voltage between ‘R&Y’ phase is sensed and all the three phase output are corrected accordingly. These units are, therefore, suitable only for use with balanced 3-phase mains supply. If balanced mains supply cannot be ensured, TYPE SE – 15-3U should be used.
