Servo Voltage Stabilizer
Optimum performance of any electrical or electronic equipment is highly dependent on the stability of the applied mains voltage. Wide deviations from the normal voltage, both on the higher side and lower side, can produce harmful effects.
PERPETUAL servo-controlled AC Voltage Stabilizers are exclusively designed to protect your costly equipment from harm caused by undesired voltage fluctuations.
PERPETUAL Servo Voltage Stabilizers are ideally suitable for computers and computer-based systems, medical diagnostic equipment, general laboratory equipment, high power communication systems, and any other application that requires a precise mains supply.
- Corrects voltage automatically and continuously.
- Induction motors operate at high efficiency when supplied with constant voltage.
- Protects costly equipment from the menace of high/low voltage, thus cutting down maintenance costs.
- Reduces production losses and improves overall plant efficiency.
- Increases productivity.
- Eligible for 100% depreciation as per Income Tax Act.
- Reduces MDI (Maximum Demand Indicator) and saves power. Reduces electricity bills by approximately 15% (subject to input voltage variation, loading, and operating hours). Saves on diesel costs, as generators are not required to run during high/ low voltage conditions.
- The average payback period for a Servo Controlled Voltage Stabilizer, due to its high energy-saving capability, is approximately 18 months. Fast correction rate with very high efficiency.
- Operates over a wide input frequency range with no waveform distortion.
- Specially designed high-performance I.C.-based control circuit for ultra-high reliability.
- Auto/Manual operation facility.
- Over-voltage and under-voltage indicators.
- Output voltage adjustability provided on the panel.
- Unaffected by Load Power Factor.
- Plug-in type glass-epoxy control cards designed for easy online serviceability.
- All components are of reputed make, conforming to relevant IS/BS standards.
- Easy accessibility from all four sides.
- Stabilizers are subjected to routine and type tests as per latest ISO standards (ISO: 9815 94).
