Features:
- Power supply module
- Designed for installation in the Universal Relays series
- UR devices support power modules for both high voltage (HI) and low voltage (LO) ranges
The UR series devices support power modules with both high-voltage (HI) and low-voltage (LO) ranges. The high-voltage module has been redesigned to address global component shortages, enabling dual power supply for critical components and optimizing the design.
The redesigned UR-TH power module is compatible with existing and previous UR hardware. Apart from the features mentioned above, the TH power module does not affect other functions of the UR devices. The TH power module can directly replace some previous power modules.
The URRHH GENERAL ELECTRIC Power supply module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
This power module is designed for general-purpose relay series, offering two voltage ranges and optional redundant power supplies. The nominal voltage for the low-voltage (LO) range is 24 to 48V (DC only), and the nominal voltage for the high-voltage (HI) range is 125 to 250V (DC and AC). This power module can power relays or dry contact input connections. The internal fuse rating of this power module is 4A/250V.
1. External Power Supply: In addition to driving the relay body, it can also supply power to the dry contact input terminals.
2. Redundancy Backup: Supports parallel installation of two power modules. If one fails, the other will immediately take over the entire load, ensuring zero system downtime.
3. Self-Diagnosis: Works with the relay self-test component to automatically assess the module's health status.
4. Power Status is clearly displayed via panel LED indicators (solid, flashing, off).
5. Built-in fuse protection (rated 4A/250V).
This module is widely used in harsh environments requiring high-reliability power protection:
1. Substation Automation: Facilitates communication and coordination between protective relays and SCADA systems.
2. Power Generation and Distribution: Used for monitoring generators, transformers, and transmission lines (distance protection, differential protection).
3. Industrial Automation: Serves as a core protection device for critical assets (such as large motors and capacitor banks) in factory power management systems.
4. Supports Digital Fault Recording (DFR) and Sequence of Events (SOE) to aid predictive maintenance.
5. Infrastructure: Applied to rail transport, highway traffic management, and telecommunications power systems.
