Physical Design & Installation

Built in a coated metal enclosure with an Integrated Junction Box and multiple 7/8 in. knockouts to simplify line-voltage and low-voltage wiring transitions. The driver uses a 2-hole flange mount and specifies 5 in. minimum installation spacing for ventilation.

Dimming & Controls

Phase dimming is supported with a leading (forward) edge MLV TRIAC dimmer only. Dimming performance is specified down to a 1% minimum dimming level. Input is 120VAC, 50/60Hz and output is 12VDC constant voltage for compatible LED loads.

Performance & Build

Protection is provided by primary and secondary auto-reset circuit breakers to help safeguard both the driver and connected LED load. The unit is Class 2 and is ETL Listed (conforms to UL 2108 and C22.2 No. 223). Environmental ratings include Dry & Damp and NEMA 3R.

Typical Applications

  • 12VDC LED tape and under-cabinet lighting
  • Linear and tube-style low-voltage LED systems
  • Residential and commercial accent lighting runs
  • Damp-location installations requiring a NEMA 3R enclosure
