Voltage Sensitive Relays
WILMAR™ Protective Relays – WOUV DC Series, Over/Undervoltage
Function:
• ANSI/IEEE C37.90-1978
TER#6M-IN3A2LSSCTRREIPWSS
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.

PRODUCT SPECIFICATIONS
Part Number
WOUV
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 .........................
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.
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.

A = 2 Form A Contacts
B = 2 Form B Contacts
H = 125 VDC Contacts
P = Transient Protection
Transient Protection - All voltage relays will withstand
momentary voltage surges of twice the nominal rated
input voltage (standard).
Option "P" provides additional transient protection
which complies with the requirements of ANSI/IEEE
C37.90-1978
