Application Examples
- Under-cabinet and cove lighting with Nora Hy-Brite and COB tape lights
- Display cases and millwork using Nora Lightbar Silk
- Accent and task lighting with Josh 24V puck systems
- Any 24V constant-voltage load up to 60W total
Installation Tips
- Power off and have a qualified electrician perform installation.
- Allow at least 5" clearance on all sides for proper ventilation.
- Input wiring (AC): Black = Line (hot), White = Neutral, Green = Ground.
- Output wiring (24V): Red = Positive (+), Black = Negative (−).
- 0–10V / PWM dimming leads: Purple = Dim (+), Pink/Grey = Dim (−).
- For best dimming performance, load the driver to a minimum of 20% of capacity.
Frequently Asked Questions
Q: Which dimmers are compatible?
A: Phase (Triac/ELV/MLV) at 120V, plus 0–10V or PWM controls at 120–277V. The driver dims smoothly to about 1%.
Q: Is this driver safe for outdoor or damp areas?
A: Yes. The enclosure is suitable for dry, damp, or wet locations when installed per instructions.
Q: What does “Class 2” mean?
A: It indicates the output meets Class 2 limits for voltage and power, simplifying installation and enhancing safety for low-voltage LED loads.
Q: What Nora products work with this driver?
A: Nora 24V systems including NUTP series tape lights, NULB-8 Lightbar, and NMP2 puck systems are listed as compatible.
Q: What are the driver’s protections?
A: Built-in over-current, over-voltage, and over-temperature safeguards help prevent damage to the driver and connected loads.
Q: What are the physical dimensions?
A: 7.87" L × 4" W × 1.67" H—allow 5" of free space around the housing for ventilation.
Q: How should I wire 0–10V dimming?
A: Keep the low-voltage dimming pair separate from AC input. Connect Purple to Dim (+) and Pink/Grey to Dim (−); do not connect these to line or ground.
Q: Is there a minimum load?
A: Yes—aim for at least 20% of rated power (≥12W on this unit) for the smoothest dimming.
