GM Lighting LineDRIVE 40W LED Driver — 12VDC

The GM Lighting LD-XD-UNV40-12 is a 40W LED Driver delivering 12VDC Constant Voltage with Universal Dimming, Class 2 safety, and an Integrated Junction Box enclosure. This versatile power supply supports 120-277V input for commercial or residential use.

Key Features

  • Power Output: 40W Max
  • Output Voltage: 12VDC Constant Voltage
  • Input Voltage: Universal 120-277VAC (50/60Hz)
  • Dimming Protocol: TRIAC, ELV, MLV, 0-10V, and PWM
  • Minimum Load: 10% (40% for MLV)
  • Dimensions: 7.93 in. L x 3.36 in. W x 1.33 in. H
  • Enclosure Type: Integrated Junction Box (Steel)
  • Safety Ratings: UL Listed, Class 2, Title 24 JA8

Physical Design & Installation

Constructed with a black powder-coated steel case, this driver includes an integrated junction box that meets NEC code requirements. The enclosure features separate compartments for line voltage and low voltage wiring, accommodating up to three 12 AWG conductors for simplified installation. The unit includes 12 in. leads for input, output, and dimming connections.

Dimming & Controls

The Multi-Dim LineDRIVE technology provides stable, flicker-free operation with a dimming range from 100% down to 1%. Phase dimming (TRIAC, ELV, MLV) is supported at 120VAC input, while low voltage dimming (0-10V, 10V PWM) is compatible with both 120VAC and 277VAC systems. A minimum load of 10% is recommended for most protocols to ensure smooth performance.

Performance & Build

This driver is engineered for longevity with an 85,000-hour life rating at 120VAC input and a 60 degree Celsius case temperature. It features comprehensive hiccup mode protection against over-voltage, over-current, and short circuits, along with over-temperature auto-recovery. The unit is UL listed for US and Canada and complies with FCC Part 15 Class B consumer limits.

Typical Applications

  • Under-cabinet LED tape lighting
  • Linear cove and accent lighting
  • Residential low voltage systems
  • Commercial display and task lighting
