Installation Tips
- Mount the canopy transformer at the feed point and verify polarity before energizing the trac.
- Use the rocker switch to test power prior to lamping and aiming downstream fixtures.
- Keep remote lead lengths short—do not exceed ~5' to minimize voltage drop on 12V runs.
- Pair with incandescent-rated loads (50–150W total). For LED loads, use Juno LED-compatible transformer models.
- For dimming, use a standard incandescent dimmer designed for electronic low-voltage.
- Always de-energize the circuit before wiring or service.
FAQ
What loads does TL546-150W-120-12AC-WH support?
This model is rated for 50–150 watts of incandescent 12VAC loads. For LED loads, use an LED-compatible Trac 12 transformer.
What is the input and output voltage?
Input is 120V AC and output is 12V AC for low-voltage trac lighting.
Can I dim this transformer?
Yes. It works with most standard incandescent dimmers. For best results, choose dimmers intended for electronic low-voltage applications.
Does it include an on/off switch?
Yes. A rocker on/off switch is integral to the unit for convenient testing and service.
How should I manage run lengths?
Keep any remote low-voltage leads short; remoting beyond about 5 feet is not recommended due to voltage drop on 12V circuits.
What are the canopy dimensions?
Approximate canopy size is 4 3/4" × 5" × 2 1/8" for a compact, surface-mounted installation.
Is TL546-150W-120-12AC-WH safety listed?
Yes. It is UL listed and CSA certified, meeting common U.S. and Canadian safety standards.
Is this product eligible for Buy American programs?
Yes. It qualifies under BAA and BABA definitions for U.S. procurement.
