Protective Relays WOUV DC Series, Over/Undervoltage Product Specifications Product Facts n PS TRI S LS INA CREW M S R TE - 32 #6 ANSI/IEEE C37.90-1978 The relay will energize at normal voltage conditions. The normally open contacts will close, and the normally closed contacts will open. The relay will de-energize during over or undervoltage conditions. Reset is automatic when the voltage returns to normal. 2 13/16 2.0 3 3 3 7/ 1/ 2 8 2 3/ 3 4 1/ 2 11/64" DIA. 4 MTG. HOLES Note: Dimensions in inches. Multiply values by 25.4 for dimensions in mm. 11 Protective Relays Nominal Voltage (±10%) — 12 VDC to 560 VDC Drop-out Point (u/v models) — 70-100% of nominal voltage, screwdriver adjustable Pick-Up Point (o/v models) — 100-125% of nominal voltage, screwdriver adjustable Output Contacts — One set N.O., One set N.C. Contact Ratings — 5 amp resistive at 120 VAC or 28 VDC Operating Temperature Range — -40˚C to +75˚C Temperature Effects — Less than 1% voltage drift over the temperature range. Power Consumption — 12 to 60 VDC models — 1 W max. 120 to 305 VDC models — 2 W max. 405 to 470 VDC models — 3 W max. 560 VDC Model — 4 W max. Time Delay — A short duration delay is provided to prevent nuisance tripping due to momentary dips or surges in voltage. The drop-out delay, following a voltage fault is 75 to 100 milliseconds Notes: 1. Remove black screws for access to the O/V and U/V trip adjustment. 2. Clockwise rotation of the adjustment potentiometer will raise the voltage trip point. 3. The adjustments are by means of a single turn potentiometer. Use a small screwdriver and do not force beyond the limit stops.
