The D65VAKP over/under voltage relays provide protection to equipment where either an over or undercurrent condition is potentially damaging. They are designed to operate when the operating voltage reaches a preset value and drop OUT when the operating voltage drops to a level below the preset value. The pickup voltage setting is user adjustable from 75 to 125% of the nominal voltage rating. As standard, the D65VAKP has an adjustable dropout setting of 75 to 95%. The relay energizes when the monitored voltage is above the pickup setting. The relay de-energizes when the monitored voltage is below the dropout setting for a period longer than the dropout time delay, which is adjustable from 0.1 to 10 s. A fixed time delay of 500 ms is available with the D65VMP series.
