Industrial 9966D75G02 Three-Phase Power Supply Module

Description:

The Westinghouse IQ DATA Control Relay 2D78533G01 with 9966D75G02 Three-Phase Power Supply Module is a microprocessor-based metering, monitoring, and protection system designed for industrial power distribution applications. It provides real-time monitoring of electrical parameters, power system diagnostics, alarm functions, and protective control capabilities for three-phase electrical networks. The 9966D75G02 power supply module allows the IQ DATA unit to derive operating power directly from the monitored three-phase system (up to 600 VAC, 50/60 Hz), eliminating the need for a separate control power source. This assembly is commonly installed in switchgear, motor control centers, substations, feeder circuits, generator systems, and industrial power management applications.

Applications:

The Westinghouse 2D78533G01 IQ DATA Control Relay is commonly used in industrial switchgear systems, utility substations, transformer feeder circuits, generator monitoring systems, motor control centers, manufacturing facilities, and electrical distribution networks where reliable power metering, load monitoring, energy management, fault detection, and system protection functions are required. The system continuously monitors electrical parameters and provides critical operating data for power management and preventive maintenance programs.
