GE Multilin URSHA UR-SHA Power Supply Module
Configured for regulated DC power conversion in GE Multilin Universal Relays platforms, the GE Multilin URSHA (UR-SHA Power Supply Module) provides direct physical/electrical execution for internal relay power distribution and dry contact input energization.
Internal power supply load dependent on connected UR relay configuration
Product Type
Power Supply Module
Compatible Platform
GE Multilin Universal Relays (UR Series)
Input Voltage
125 to 250 VDC / 100 to 240 VAC
Dry Contact Voltage Output
48 VDC auxiliary output
Diagnostic Interface
Power health alarm contact and front-panel LED status
Protection Feature
Conformal coating for moisture, contamination, and chemical exposure resistance
Deterministic Network and Industrial Control Integration
The URSHA module operates within the GE Multilin UR plug-in architecture and provides the internal DC supply rails required by relay processors, communication modules, and I/O assemblies. The standardized backplane interface supports modular replacement procedures and maintains compatibility with UR series protective relay chassis including B30, C30, L90, T60, and N60 configurations.
Firmware flash compatibility remains dependent on the host UR relay platform and installed hardware revision. The module performs supply health supervision through internal diagnostics and provides alarm indication through relay status contacts and front-panel LED monitoring.
Frequently Asked Questions (FAQ)
Q: Can the URSHA module be replaced while the relay system remains installed? A: The URSHA uses the UR series plug-in modular architecture. Replacement procedures must follow the applicable relay maintenance instructions and power isolation requirements before module removal.
Q: What protection method is applied to the electronic assembly? A: The module uses conformal coating to protect electronic components against moisture, airborne contaminants, chemical corrosion, and environmental stress.
Q: What diagnostic information is available from the module? A: The module provides internal supply monitoring, front-panel LED status indication, and power health alarm contact output for relay system supervision.
Field Installation Guidelines
Install the URSHA module only in the designated power supply slot of compatible GE Multilin UR series chassis.
Verify auxiliary AC or DC input wiring before energizing the relay assembly.
Maintain proper separation between power wiring, communication wiring, and sensitive signal conductors.
Connect grounding and shielding according to the relay cabinet grounding design and site electrical standards.
Inspect the module connector, backplane interface, and mechanical locking mechanism before installation.
Confirm LED status and alarm contact behavior after power application.
Avoid handling the coated circuit surfaces with contaminated tools or materials during maintenance activities.
