The Performances of any electrical equipment is optimum at its rated Voltage. Both, over Voltage and under-voltage produce harmful effects .Under-Voltage generally reduces efficacy. Whereas over voltage Shortens life.
The ARMO Numerical Servo controlled Voltage Stabilizers have been specially designed incorporating the latest in solid state Technology to protect your equipment from harms caused by undesirables Voltage Fluctuations.
