The Omron K8AK-VW3 100-240VAC monitors AC or DC supplies from 20 V to 600 V, adjustable for over- or undervoltage detection. The trip threshold is set with a potentiometer; a separate dial adjusts the delay from 0.1 second to 30 seconds, which lets you ignore brief dips or surges that don't affect the load. The SPDT relay output switches 5 A at 250 VAC, so it can directly drive a contactor coil or annunciator.
