The WUV-125DC-H is a DC undervoltage protective relay designed for system monitoring and protection. It features a screwdriver-adjustable drop-out point, settable between 70% and 100% of the nominal voltage. To prevent nuisance tripping from transient voltage fluctuations, the relay incorporates a time delay of 150-300 ms. This specific model is designated by the 'H' option, providing contact ratings of 3A at 125VDC, and features one set of normally open and one set of normally closed output contacts. It is ideal for applications requiring reliable undervoltage protection for DC-powered equipment.
