GE UR1HH

Product Introduction: The GE UR1HH is a high-power supply module for the GE Multilin UR (Universal Relay) series. It is the high-voltage power supply variant, rated for 125–250 V DC and 100–240 V AC (50/60 Hz) input. This contrasts with the low-power module (UR-SH) rated at 24–48 V DC. The module plugs into the UR relay chassis and provides regulated power to the CPU, CT/VT, digital I/O, and communication modules within the universal relay.

Description

GE UR1HH

Technical Specifications:

  • Series: GE Multilin UR (Universal Relay)
  • Module Type: Power supply module (high-voltage variant)
  • Input Voltage: 125–250 V DC; 100–240 V AC, 50/60 Hz
  • Output Power: 35 W (per UR-RH specification)
  • Isolation Voltage: 2000 (UR-RH variant)
  • Capacitors: 27 electrolytic capacitors (UR-RH variant)
  • Mounting: Plug-in module inside UR relay chassis (hinged front panel access)
  • Operating Temperature: Per UR relay chassis specifications

Functional Features:

  • High-voltage input range (125–250 V DC / 100–240 V AC) for substation battery and AC auxiliary supplies
  • Plug-and-play modular design allows quick replacement without rewiring
  • Hinged front panel on UR relay provides easy access to the module rack for installation and upgrade
  • Compatible with EnerVista UR software for configuration and diagnostics
  • Provides regulated power to all internal UR modules (CPU, CT/VT, digital I/O, communication)

Application Scenarios:

  • Substation protection relay power supply for UR-series universal relays
  • Power generation, transmission, and distribution protection systems
  • Industrial plant electrical protection requiring high-voltage auxiliary supply
  • Backup protection schemes using station battery (125/250 V DC)

Performance Parameters:

  • 35 W output power sufficient for fully loaded UR relay configurations
  • 2000 V AC isolation between input and output for safety and noise immunity
  • Wide input voltage range accommodates various substation auxiliary supply voltages

Material and Structural Characteristics:

  • Black matte module housing for aesthetics and PCB protection
  • Industrial-grade PCB with 27 electrolytic capacitors for power filtering
  • Plug-in connector interface matching UR relay chassis backplane
  • Front-mounted status LED for power indication

Working Principle: The module converts the high-voltage DC or AC input (125–250 V DC / 100–240 ) to regulated low-voltage DC outputs required by the UR relay’s internal modules. The switching power supply circuit provides galvanic isolation (2000 V AC) between the input and output, filtering input transients and delivering stable power to the CPU, CT/VT, and I/O modules. Installation Requirements:

  • Open the hinged front panel of the UR relay to access the module rack
  • Disconnect the old module and pull the insertion clip to remove it
  • Insert the new UR1HH module into the correct slot
  • Replace the module only with a similar module (note the slot position before removal)
  • Close and secure the hinged front panel

Usage Notes:

  • Replace the module only with an identical UR1HH or compatible high-voltage power supply module
  • Record the slot position before removing an old module to avoid misplacement
  • Verify input voltage matches the module rating (125–250 V DC or 100–240 V AC) before energizing
  • Use EnerVista UR software to verify power supply status and diagnostics
  • Ensure the UR relay chassis is de-energized before module replacement when possible
