HOLES Protective Relays WOUV DC Series, Over/Undervoltage Product Specifications Product Facts Nominal Voltage (10%) n ANSI/IEEE C37.90-1978 12 VDC to 560 VDC Drop-out Point (u/v models) 70-100% of nominal voltage, screwdriver adjustable Pick-Up Point (o/v models) The relay will energize at 13 100-125% of nominal voltage, 2 /16 normal voltage conditions. screwdriver adjustable The normally open contacts Output Contacts One set N.O., will close, and the normally One set N.C. closed contacts will open. Contact Ratings The relay will de-energize 5 amp resistive at 120 VAC or 28 VDC during over or undervoltage Operating Temperature Range conditions. Reset is auto- -40C to +75C matic when the voltage Temperature Effects returns to normal. Less than 1% voltage drift over the tem- perature 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. Note: Dimensions in inches. Multiply values by 25.4 for dimensions in mm. Time Delay A short duration delay is provided to prevent nuisance tripping due to momentary dips or surges in volt- 11 age. 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 adjust- ment. 2. C lockwise rotation of the adjust- ment potentiometer will raise the Single Phase 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.
