Voltage Sensitive Relays

WILMAR™ Protective Relays – WOUV DC Series, Over/Undervoltage

Function:

• ANSI/IEEE C37.90-1978

The relay will energize at normal voltage condi-

tions. 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.

Temperature Effects.........................

Power Consumption ........................

Less than 1% voltage drift over the temperature range.

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.

Transient Protection - All voltage relays will withstand

momentary voltage surges of twice the nominal rated

input voltage (standard).

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

Time Delay ........................................

Option "P" provides additional transient protection

which complies with the requirements of ANSI/IEEE

C37.90-1978

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.

Consult factory for additional models.
