UDR Series AVR is integrated the self-develop patent controll-mode, achieved the authentic zero-crossing technology, which makes the relays switching on/off at the zero point, it reduces the shock to the relays and to the loads at the switching point, so that you can gain more smooth output and more durable relays.
