Voltage Sensitive Relays Function: WILMAR Protective Relays WUV/WOV DC Series ANSI/IEEE C37.90-1978 Undervoltage Models - The relay is energized at normal voltage, N.C. contacts will open and N.O. contacts will close. The relay will de-energize when the voltage drops below the U/V set point. Overvoltage Models - The relay is de-energized at normal voltage, N.C. contacts are closed and N.O. contacts are open. The relay will energize when the voltage rises above the O/V set point. Note: Dimensions in inches. Multiply values by 25.4 for dimensions in mm.

Less than 1% voltage drift over the temperature range. A = 2 Form A Contacts Power Consumption ........................ 12 to 60 VDC models: 1 W max. B = 2 Form B Contacts 120 to 305 VDC models: 2 W max. H = 125 VDC Contacts 405 to 470 VDC models: 3 W max. P = Transient Protection 560 VDC Model: 4 W max. Transient Protection - All voltage relays will withstand A short duration delay is provided to prevent nuisance Time Delay........................................ momentary voltage surges of twice the nominal rated tripping due to momentary dips or surges in voltage. input voltage (standard). The drop-out delay, following a voltage fault is 75 to 100 milliseconds Option provides additional transient protection which Notes: complies with the requirements of ANSI/IEEE C37.90-1978 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. Consult factory for additional models. 3. The adjustments are by means of a single turn potentiometer. Use a small screwdriver and do not force beyond the limit stops.
