Features:
- Accepts both 100-240V AC and 125-250V DC for versatile industrial integration
- Compact form factor with vertical orientation for space-constrained panels
- Supports parallel operation to ensure system availability during a power supply failure
The GE URRHV is designed to accept a broad range of input voltages, including 100-240 VAC and 125-250 VDC . This flexibility ensures that the module can be integrated into various industrial and utility environments without needing external power conditioning. The URRHV provides a stable, regulated DC power output to the relay chassis's backplane, which is essential for the consistent operation of the CPU and I/O modules. This reliable power delivery is crucial for maintaining the accuracy and timing of the relay's protection algorithms
The "V" in its model name signifies that the URRHV is specifically designed for vertical mount applications . This is a critical differentiation, as vertical mount units are more compact than their horizontal counterparts, making them the ideal choice for power systems with limited available space. The URRHV's reduced size allows it to be integrated into smaller control panels without compromising performance, ensuring that key protective functions can be deployed even in space-constrained environments
The URRHV includes a redundant power supply option, allowing two modules to be installed in parallel within a system. In this configuration, if one power supply experiences a fault, the other instantly takes over the full load, ensuring zero downtime for critical protection systems . This feature is paramount in high-availability applications like utility substations. The URRHV also features front-panel LEDs that provide immediate visual feedback on its operational status and potential faults, which greatly simplifies troubleshooting and maintenance .
The URRHV GE Power Supply Module may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Utility Substation Automation: Powering Intelligent Electronic Devices (IEDs) used for transmission line protection (e.g., L90, D60), transformer management (T60), and bus protection (B30).
- Power Generation Plants: Deployed in thermal, hydro, nuclear, and renewable plants to power generator protection relays (G60) and station service switchgear.
- Heavy Industrial Facilities: Operating inside localized electrical houses (E-Houses) and control rooms for steel mills, petrochemical plants, mining operations, and pulp/paper facilities.
- Power Supply Health Monitoring: Integrates with the UR relay’s internal self-diagnostics. If output voltage drifts or a component fails, it triggers a hardware alarm and logs an event in the relay’s SOE (Sequence of Events) recorder.
- Redundant Switching Control: When paired with a second supply in a dual-power configuration, the module shares the load (typically 50/50). If one fails, the other assumes 100% load dynamically with zero switchover time.
- Overvoltage & Overcurrent Protection: Internal circuitry clamps unexpected voltage spikes and limits excessive output currents, preventing damage to the sensitive microprocessor boards inside the relay.
- Physical Mounting: Slide the module into the designated slot (usually Slot R or S at the rear of the UR chassis) along the vertical guide rails. Ensure the multi-pin backplane connector aligns perfectly before firmly pushing it into place.
- Wiring & Grounding: Terminal connections must handle 100–240 V AC or 125–250 V DC input. Secure a dedicated low-impedance ground wire to the chassis grounding stud right next to the module to prevent electrical noise.
- Firmware & Hardware Matching: When replacing older generations, verify that the UR chassis firmware (CPU module) supports the specific URRHV revision. In mixed dual-power setups, both modules should ideally match in voltage rating and generation.
