Air-Cooled Stabilizer -3 kva

Optimum performance of sophisticated electronic equipment is highly dependent on the stability of the mains voltage. The continuously fluctuating mains supply, transients, spikes & surges produce harmful effects.

The Stabilizers are preferred over voltage Stabilizer as the Stabilizer have relays that are when switched cause the output voltage to be interrupted for a short time. This type of interruption or transient many not be good for computers. In comparison to voltage Stabilizer, the Stabilizers ensures a clean, spike-free and controlled output voltage.

BE Servo system constant voltage transformer gives an effective solution to all these problems.

Constant voltage Transformer are based on Ferro-Resonance Principle & it consists of two basic components i.e., Ferro-Resonant transformer and capacitor

Recommendations

Place the Stabilizer away from equipment and all magnetic display and storage devices like diskettes, monitors, tapes etc.

It is safer to connect Stabilizer to mains supply through a 3 Pin socket ensuring thereby the availability of proper 'Earth' connection

Switch ON the Stabilizer first then the attached peripherals and while switching OFF, switch OFF attached peripherals first and then the Stabilizer

In case of supply from a generator, check frequency, Stabilizer is not be used if frequency variation is beyond 50 +/-1Hz

Switch OFF the Stabilizer when not in use.

      Not to be used for high inductive LOADS like motors.
