| Voltage Sensitive Relays WILMARTM Protective Relays - D100X Series, Close Differential Function: * ANSI/IEEE C37.90-1978 * UL file No. E58048 * CSA file No. LR61158 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. 0.5 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. Note: Dimensions in inches. Multiply values by 25.4 for dimensions in mm. 2.6 6 3.0 5 3. 2.2 50 3 11/64" DIA. 4 MTG.

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. Consult factory for additional models. 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. 26 Tyco Electronics / www.tycoelectronics.com / Factory Direct Technical Support: 800-253-4560, ext. 2023 (U.S., Canada, Mexico) or 805-220-2020, ext. 2023 (International) |
