GE Multilin URRHH Universal Relay High Voltage Power Supply Module

The URRHH (Model: UR-RHH) is a specialized, high-capacity power supply module designed for the GE Multilin Universal Relay (UR) series. As a critical infrastructure component, the URRHH (Part Number: URRHH) provides the necessary auxiliary power to drive the relay's internal logic, communication ports, and I/O modules. It is engineered to support wide-range input voltages, making it compatible with both standard AC utility power and station DC battery banks, ensuring the protection relay remains operational during severe grid disturbances or total AC power loss.

Built for maximum reliability in high-voltage environments, the URRHH (Model: URRHH) features advanced galvanic isolation to decouple the sensitive microprocessor electronics from the noisy substation auxiliary power bus. This second-generation module is a "High" voltage variant (denoted by the 'HH' suffix), optimized for 125–250 VDC and 100–240 VAC applications. Its rugged construction and wide operating temperature range (-40°C to +85°C) meet the stringent E-E-A-T (Expertise, Authoritativeness, Trustworthiness) requirements for utility-grade protection systems.

Detailed Technical Specifications

The URRHH (Model: UR-RHH) is designed as a plug-in module for the standard UR chassis, offering high efficiency and a modular maintenance path.
