RL12-75A-277

Power Transformers Overview

The Hatch Lighting RL12-75A-277 is a hardwired electronic step-down transformer designed for low voltage lighting applications. It accepts an input of 277 VAC and provides a stable 11.5 VAC output at a maximum power rating of 75 watts, supporting up to 6.25 amps. The unit features chassis mounting with side leads and includes auto-reset protection against short circuits. It meets UL Class 2 safety standards and operates within a maximum case temperature of 90°C.

Power Transformers Feature Summary

• Electronic encapsulation for compact integration
• Auto-reset short circuit protection
• UL Class 2 certified safety isolation

Power Transformers Applications

• Low voltage halogen lighting systems
• Commercial architectural lighting installations
• Hardwired fixture power supplies

Power Transformers Procurement Notes

Verify the specific voltage requirement (11.5V vs 12V) matches the connected load specifications. Confirm that the installation environment does not exceed the 90°C maximum case temperature rating. Ensure proper chassis mounting clearance is maintained for thermal dissipation during operation.

Power Transformers Selection Notes

Select this model specifically for 277VAC primary circuits requiring 11.5VAC secondary output. This component is suitable for applications where chassis mounting is preferred over surface or track mounting. Consider the 75W power limit when calculating total load requirements for connected fixtures.

Power Transformers Part Context

This part belongs to the Hatch RL12 series of electronic transformers. Variants such as the RL12-75A differ by primary voltage input, while the -277 suffix explicitly denotes the 277VAC input configuration. The series utilizes encapsulated electronic technology for reliable performance in lighting control environments.

Power Transformers Replacement Considerations

Direct substitutes include other models from the same manufacturer series with matching electrical ratings. Verify compatibility regarding input voltage, output voltage, and physical mounting dimensions before replacement.
