GE URRHH
Product Introduction
GE URRHH is a high-efficiency power supply module designed specifically for the GE Multilin UR Series Universal Relay system. It serves as the critical power backbone for the rack, converting incoming AC or DC power into the stable voltage required for the relay’s internal components and dry contact input connections.
This industrial automation unit features a compact design and a wide input voltage range, making it highly adaptable for various power grids. To ensure system integrity, it includes comprehensive hardware protection and self-test diagnostics that automatically evaluate its health and alert operators via panel LEDs in the event of a critical fault.

Quality Control Process
We validate every GE URRHH before shipment to ensure operational readiness:
- Visual & Physical Inspection: Connectors, internal fuse, and PCB components are checked for physical damage, corrosion, or thermal stress.
- Functional Test: Powered up with test voltage to verify correct output, LED status indicators, and backplane communication.
- Protection Verification: Overload and overvoltage protection circuits are simulated to confirm they trigger accurately and safely.
- Cleaning & Packaging: Units are cleaned, anti-static shielded, and desiccant-packed to prevent moisture damage during transit.
Replacement Pitfall Guide
❗ Voltage Range Verification: The URRHH module is available in different voltage ranges (Low Range 24-48V DC vs. High Range 125-250V AC/DC). Always verify the exact voltage rating on your existing module’s nameplate to prevent catastrophic failure.
❗ Internal Fuse Rating: The internal fuse is rated at 4A/250V. Never attempt to bypass or replace the internal fuse with a higher-rated component, as this will compromise the module’s protection mechanisms and void safety certifications.
❗ Diagnostic LED Monitoring: The module features built-in self-tests. If the “Shutdown” or fault LED illuminates upon installation, do not force the system to run. Investigate the backplane for short circuits or incompatible modules before replacing the power supply again.
❗ Redundancy Options: Depending on the specific UR chassis configuration, this module may support or require redundant power options. Verify your system’s redundancy requirements before installing a single module.
