Product Overview

The GE Multilin UR-RHH (also known as URRHH) functions as the primary energy source for the GE Universal Relay (UR) platform. This high-capacity, plug-in module converts substation auxiliary power into the regulated DC voltages required to operate the relay's microprocessor, communication hardware, and expansion I/O. We supply this unit as 100% Brand New, ensuring your protective systems remain online during critical grid disturbances. The "HH" designation identifies this as a high-voltage variant, specifically optimized for standard station battery banks and AC utility mains.

Technical Specifications

The UR-RHH provides high-efficiency power conversion with extensive tolerance for voltage fluctuations.

Power Capacity	35 W (DC) / 35 VA (AC)
Holdup Time	100ms (Typical at nominal voltage)
Dielectric Strength	2.3 kV AC (Input to Backplane/Chassis)
Operating Temp	–40°C to +85°C (–40°F to +185°F)
Protection	Internal Surge Filtering & Galvanic Isolation
Status Monitoring	Front Panel LED & Internal Form-C Alarm Contact
Weight	0.62 kg (1.37 lbs)

Engineering Advantages

Superior Grid Resilience: The UR-RHH maintains a 100ms holdup time. This bridge allows the relay to ride through momentary voltage dips or the transition time required for backup generators to start, preventing nuisance restarts of critical protection logic.
Robust Galvanic Isolation: Advanced isolation circuitry decouples the sensitive relay CPU from the noisy substation DC bus. This design blocks common-mode noise and prevents high-voltage transients from damaging the internal logic components.
Wide Thermal Operating Window: Engineered without fans, the module utilizes convection cooling to operate in temperatures ranging from –40°C to +85°C. This eliminates a common mechanical failure point and allows for installation in unconditioned outdoor kiosks.
Integrated Self-Diagnostics: A dedicated internal Form-C hardware alarm contact monitors the health of the power supply. If the module detects an internal failure, it closes the contact immediately to alert the SCADA system, enabling proactive maintenance before the relay loses protection capability.

FAQs

Can the UR-RHH handle both AC and DC power simultaneously?

The module accepts either AC or DC input. While most substations provide a single primary source (usually a station battery), the UR-RHH seamlessly processes whichever input you connect, provided it falls within the rated operational range (88–300VDC or 88–265VAC).
How do I confirm the power supply is functioning correctly?

The front panel includes a Power Health LED. A solid green light indicates the module is delivering correct voltages to the backplane. For remote monitoring, wire the internal Form-C alarm contact to a digital input on the relay or a remote terminal unit (RTU).
Does this module replace the low-voltage version?

No. The UR-RHH is specifically for high-voltage (125V/250V) environments. If your substation utilizes a 24V or 48V battery bank, you must use the corresponding low-voltage power supply module to avoid damaging the hardware.
