Overview

The UR-1HH is a power supply module from GE Multilin designed for use in the Universal Relays series. This high-power unit operates with a power rating of 125-250 VDC and 100-240 VAC at 50/60 Hz.

Technical Specifications

• Manufacturer: General Electric Multilin (GE)
• Weight: approx. 1.15 kg

Dimensions:

• Length: approx. 15 cm
• Width: 18 cm
• Height: 4 cm

Power Ratings:

• DC: 125-250 V
• AC: 100-240 V at 50/60 Hz

Module Replacement:

• Features a hinged faceplate for easy access to module installations.
• Users can replace faulty modules by disconnecting connections, removing clips, and inserting new modules into the correct position.
• Modules must be replaced with like models, so it’s important to note the original slot.

Safety Considerations:

• Replacement should only be done with control power removed to avoid damage or injury.
• Users should utilize electrostatic discharge protection, such as a static strap, when handling modules while the relay is energized.

Additional Information

• The power rating of the UR-1HH allows for flexibility in power supply options, as Universal Relays can accept modules from both high and low voltage ranges.
• Originally, the input voltage range for earlier generations was 88 to 300 VDC, while the newer SH modules have a range of 88 to 400 VDC.
• It is advisable to use power supply modules from the same generation within a single Universal Relay for optimal performance.
