The TOMZN TOVPD1-60-EC is an excellent "set it and forget it" device. By properly configuring the voltage thresholds and the recovery delay, you can significantly extend the lifespan of your sensitive home electronics.
The relay connects the load only when voltage and current are within the safe ranges. Do not exceed the rated current of 63 A; if your load requires more, use an external contactor controlled by the relay’s output. tomzn tovpd1-60-ec manual
