MA-COM D100-4X

Voltage Sensitive Relays
WILMAR™ Protective Relays – D100X Series, Close Differential
Function:
• ANSI/IEEE C37.90-1978
• UL file No. E58048
• CSA file No. LR61158
0.5
Close Differential Relays are voltage sensitive. The
pick-up and drop-out voltage settings are independently adjustable, which allows precise setting of the
differential voltage. This relay is available in a wide
range of AC and DC voltages. Their primary application is the sensing and control of transfer switches.
Operation:
See Part Number
Selection
Monitors a single phase AC signal, and is used for
undervoltage detection. Has separate pick-up and
drop-out voltage settings, providing an adjustable
hysteresis.

Inverse Time Drop-Out: The differential relay contains a time delay before operation so that
momentary voltage transients do not aftect the operation of the relay. The time delay has an
inverse time characteristic so that excessive voltage conditions will cause a more rapid dropout. This time delay is approximately 200mSec. (12 cycles) at the trip settings and
decreases to 30 mSec. at approximately 15% beyond the trip settings.

Notes:
1. Remove black nylon protective screws to gain
access to the two internal adjustment
potentiometers.
2. Clockwise rotation of the pick-up and drop-out
adjustment will raise the voltage trip point.
3. The relay contacts are shown in the de-energized
state.
