GE Multilin UR-SHA – High Voltage Power Supply Module

The GE Multilin UR-SHA is a high-performance power supply module designed for use with GE’s Universal Relay (UR) series. As one of the latest advancements in GE’s UR power supply lineup, the UR-SHA delivers robust and reliable power delivery for relay systems while enhancing efficiency and safety. It supports higher voltage applications and offers backward-compatible improvements over earlier-generation modules.

Technical Specifications

• Manufacturer: GE Multilin

• Manufacturing Location: Markham, Ontario, Canada

• Weight: Approx. 2 lb, 2 oz (0.96 kg)

• Dimensions: Approx. 6.5” (L) × 6.5” (W) × 1.75” (H)

• Software Support: EnerVista UR

Product Overview

The UR-SHA is a high-voltage power supply module within GE’s Universal Relay platform. It provides power to both the relay and its associated dry contact input connections.

• Input Voltage Range: 125–250 V (nominal)

• Power to Dry Contacts: 48 V DC

This high-power module differs from lower-voltage UR modules (e.g., 24–48 V DC nominal) and is optimized for applications requiring greater voltage support. Users should ensure system compatibility to avoid damage caused by incorrect voltage input.

Diagnostic & Maintenance Features

• Integrated with the UR series’ self-diagnostic capabilities

• Monitors hardware health and identifies potential issues in real-time

• LED indicators on the faceplate provide clear status for:

• Power supply health

• Operational or failure states

These features streamline troubleshooting and allow for proactive maintenance.

Frequently Asked Questions (FAQ)

Q: How does the UR-SHA differ from earlier generation UR power supply modules (UR-1H and UR-RH)?

A:
The UR-SHA belongs to the UR-SH third-generation series and brings multiple improvements over the first (UR-1H) and second (UR-RH) generation modules:

These enhancements improve operational reliability, energy efficiency, and thermal performance in demanding environments.
