- Power Conditoners -

Product Description

Power Conditioner is a combination of Servo Controlled Voltage Stabiliser and Isolation Transformer.

Servo Voltage Stabilisers are designed to ensure that their output voltage remain constant irrespective of the voltage swings in the incoming power supply. Voltage fluctuations are a common phenomenon in power supply system, may result into erratic behavior, malfunction or even break down leading to expensive repairs, production loss and missed commitments. Their high efficiency and the ability to withstand instant load variations make them an ideal choice for protection of expensive and sensitive equipment.

Isolation Transformer are designed to obtain the isolation between incoming power supply and a powered circuit or powered equipment for the safety and security purpose. Switching of electrical utilities in Industrial & Commercial environment generates spikes & high frequency power line Noises. The spikes can cause the failure of Electronics circuits, insulation of motors or drives. The high frequency noises can interfere with Digital-Electronic equipment causing data corruption, erratic behavior, loss of memory etc.
