Solid State Automatic Voltage Stabilizer

Solid State Automatic Voltage Stabilisers utilizing PWM AC to AC Converter are highly reliable. No moving parts, high efficiency and maintenance-free.

Intact Controls, SS & SS3 Series Voltage Stabiliser / Regulator utilizes the latest in High speed PWM & IGBT technology to ensure the mains voltage remains constant at all times. As a High speed PWM & IGBT solution, SSR & SSR3 stabilisers utilise a complex, yet highly reliable, electronic design principle to increase or reduce the magnitude of the voltage in a series transformer winding, thereby delivering and maintaining a constant output voltage. The arrangement is realised using Pulse Width Modulation technique. The duty ratio of the PWM signal decide the magnitude of the voltage in the series winding to increase or decrease. For example, when the input voltage drops, the duty ratio increase to make up the voltage drop.
