Single-phase voltage stabilizer 1 - 30 kVA | V series

automatic

This single-phase servomotor automatic voltage stabilizer (AVS) is designed to cater for input voltage variation from single phase, at a voltage of 230V. The excellent output voltage accuracy is within ±1.5% set value, while the regulation response time is normally between 0.05 and 0.07 seconds. This item requires very little maintenance because of the design simplicity. Easy installation and suitability for special configurations and voltages are also available. The QPS servo-motor automatic voltage provides continuous motoring of the output voltage, using an electronic control circuit, comparing the instantaneous output voltage. The changes caused by the fluctuation of supply voltage cause an electric signal to be transmitted to the servo-motor. This motor is coupled onto the brush gear of the variable transformer and causes the brush gear to rotate until the restoring point of the appropriate voltage. This stabilization method contributes towards the increased performance of this item.
