Description
It is designed to protect automatic gas boilers from voltage surges in the 220V AC network. It disconnects the protected equipment from the network when the voltage goes beyond the upper and lower thresholds. After the voltage returns to the normal range, the protected device, after a delay, is connected to the network. The thresholds and delay time are set by the manufacturer and cannot be changed by the user. The operating mode indication is a three-color LED. When the device is triggered by the lower limit, the indicator lights up red, when triggered by the upper limit, it lights up yellow. When the network voltage is normal, the indicator lights up green. The series is made on analog components from the world's leading manufacturers of radio components. The barrier contains a high-frequency impulse interference filter that protects the electronic components of the devices from breakdown.
