Air Cooled Servo Voltage Stabilizer

STEPON POWERMAC is the leading manufacturer, supplier and exporter of Air Cooled Servo Voltage Stabilizer. With ultra-modern technologies and excellent output, it is rated as the finest stabilizer in the international market.

The innovative Air Cooled Servo Stabilizer has been developed to control voltage fluctuation with absolute perfection. It is capable of providing stabilized output within range of +1% nominal value. Available in two most advanced configurations—balanced load and unbalanced load, it has been designed to meet differential needs with precision.

The balanced load is able to detect voltage variation in one phase. The unbalanced load boasts of separate motorized auto-transformers for each phase. The output waveform is not affected by power factor.

It is equipped with the advanced micro controller, digital LCD display for accurate RMS voltage, auto/manual facility. It provides complete protection from short circuit, single phase prevention, and overload protection and over current electronic protection. It is unrivalled on every parameter.

With exceptionally rigid construction, the voltage stabilizer is extremely long lasting.
