Description

The GE URRHV is a second-generation high-voltage power supply unit engineered for the Multilin Universal Relay (UR) platform. This module provides stable and efficient energy to the relay’s internal processing and communication circuits. Because it features the “V” vertical designation, engineers must install it in vertical mount chassis configurations. This specific orientation ensures proper heat dissipation and secure mechanical fitment within the relay rack. The URRHV serves as a foundational component for substation protection and industrial automation systems worldwide.

Input Voltage and Power Rating

This power module supports a versatile range of input sources to accommodate various utility and industrial standards.

• AC Input Range: 100 to 240 VAC at 50/60 Hz
• DC Input Range: 125 to 250 VDC
• Maximum Power Consumption: 35 VA for AC operations
• Maximum Power Output: 35 W for DC applications
• Voltage Tolerance: Designed to withstand standard industrial fluctuations without interruption

Physical Dimensions and Installation

The compact footprint of the URRHV allows for efficient space management within high-density control panels.

Visual Monitoring and Redundancy Features

The URRHV module incorporates intelligent diagnostic tools to maintain high system availability. Integrated LED indicators on the faceplate provide immediate visual status for power health and detected fault conditions. Furthermore, this module supports parallel operation with a second power supply unit. This dual-redundant configuration prevents system downtime if a single power source fails. Consequently, the relay continues to protect critical assets without any loss of functionality. These safety features make the URRHV ideal for mission-critical electrical infrastructures.
