Applications
- Under-cabinet and millwork lighting: Hardwired power for Lumaris tape light controllers in kitchens, bars, and built-ins.
- Accent and cove lighting: Clean Class 2 power delivery for architectural tape light layouts.
- Multi-zone tape light installations: Power up to 3 compatible wireless controllers from one interface for expanded coverage.
- Hardwired retrofit projects: 120/277 V~ input support for residential and light commercial applications.
Installation Tips
- Safety first: Disconnect power before servicing or installing the unit.
- Mounting location: Use cabinet or surface-mount locations, installed remotely from the wireless controller and tape light.
- Clearance: Maintain a minimum of 2 in (51 mm) between the power interface and any other equipment or surface.
- Mounting hardware: Drill pilot holes with a drill bit no larger than 5/64 in (2 mm), leave 0.25 in (6.35 mm) of each screw protruding, then engage the keyhole slots and slide into place.
- Wire management: Open only the necessary knockouts to route wiring into the integrated wiring compartment.
- Wiring approach: For wireless controllers programmed in separate zones, homerun wiring of LED+ and LED- helps minimize interaction between controllers; T-tap wiring may result in subtle interaction.
- Wire gauge compatibility: Power interface leads and provided connectors accept 12 AWG to 20 AWG (4.0 mm2 to 0.75 mm2) wires; wireless controller terminals accept 14 AWG to 22 AWG (2.5 mm2 to 0.50 mm2) wires.
- Finish the install properly: Replace the top cover to contain all wire connections, then reapply power.
FAQ
What does the LU-PH3-B power interface do?
The LU-PH3-B converts 120/277 V~ input power into a Class 2, constant-voltage 24 V- output to power compatible Lumaris tape light wireless controllers and their connected LED tape loads.
What is the maximum output rating?
The LU-PH3-B provides up to 96 W of output power.
What is the allowable load range?
The specified output load range is 2 W to 96 W at high-end.
How many controllers can one LU-PH3-B power?
One LU-PH3-B can power up to 3 compatible wireless controllers, while staying within the total 96 W limit across all connected tape.
What input voltages are supported?
The LU-PH3-B operates on 120/277 V~, 50/60 Hz.
What protective features are built in?
It includes built-in thermal protection and an output that is open-circuit protected, short-circuit protected, and overload protected.
Is it suitable for indoor installations?
Yes. The LU-PH3-B is specified for indoor use only and operates from 32 °F to 104 °F (0 °C to 40 °C).
Are there mounting or clearance requirements?
Yes. It is intended for cabinet and surface mount use, and the installation guidance calls for a minimum of 2 in (51 mm) clearance between the interface and any other equipment or surface.
What wiring method is recommended for separate zones?
When controllers are programmed in separate zones, homerun wiring of LED+ and LED- is recommended to minimize interaction between controllers; T-tap wiring may result in subtle interaction.
