Description
This 40W emergency LED driver is purpose-built for 480V electrical systems, accepting a 277–480VAC input and delivering 310–500VDC emergency output to maintain illumination for a minimum of 90 minutes during a power failure. Designed exclusively for LED luminaires with 347–480VAC input voltage, the driver powers 0-10V dimmable fixtures up to 300W and fits inside high bays, troffers, and panel fixtures across industrial and commercial environments. Integrated self-diagnostic circuitry performs monthly 30-second and annual 90-minute discharge tests per NFPA 101, while the IP65-rated slim-profile body with flexible conduit wiring installs cleanly inside fixture housings. UL 924 Listed for the US and Canada and CEC Title 20 compliant, the unit includes a test switch and charge indicator kit and is backed by a 5-year warranty.

Features +−
- Provides 40W of constant emergency output power, automatically activating when AC power is interrupted and delivering 310–500VDC to maintain illumination through the connected LED driver.
- Designed exclusively for LED luminaires with an input voltage of 347–480VAC — this driver cannot be used with fixtures rated below 347VAC.
- Powers 0-10V dimmable fixtures up to 300W; a 0-10V dimming driver is required for proper emergency operation on fixtures above the emergency driver's rated wattage.
- Accepts a 277–480VAC input voltage range at 50/60Hz, supporting 277V, 347V, and 480V commercial and industrial electrical systems.
- Integrated self-diagnostic circuitry automatically conducts a 30-second discharge test every 30 days and a full 90-minute discharge test every 365 days per NFPA 101 Life Safety Code, then restores to normal charging without manual intervention.
- Provides a minimum of 90 minutes of constant emergency illumination in compliance with life-safety code requirements for commercial egress lighting.
- Three-way battery protection covers over-temperature, over-charge, and over-discharge conditions to safeguard battery health and extend service life.
- IP65 waterproof rating protects internal electronics against dust ingress and low-pressure water jets in damp or wet-adjacent locations.
- Built-in 3kV surge protection guards the driver and connected fixture against transient voltage spikes in 480V industrial electrical environments.
- Lithium-ion battery pack with low 12W recharge power draws minimal standby current, with a full recharge time of 24 hours after complete discharge.
- Slim profile body measures 12.33" × 2.33" × 1.66" with flexible conduit wiring and ½"-14 NPSM connector for clean in-fixture installation inside high bays, troffers, and panel housings.
- Included test switch and charge indicator kit is available in metal one-piece or plastic integrated styles to suit different fixture and ceiling configurations.
- Rated for damp locations and plenum spaces with a maximum mounting height of 30.3 feet, suitable for industrial and high-ceiling commercial installations.
- Constant power output design maintains consistent 40W delivery even as the lithium-ion battery voltage decreases during the discharge cycle.
- UL Listed for the United States and Canada, tested to UL 924 and CSA C22.2 No. 141, and compliant with CEC Title 20 and NFPA 101 Life Safety Code requirements.
- Suitable for both field retrofit of existing 480V fixtures and factory installation in new construction projects.
- Backed by a 5-year warranty covering defects in materials and workmanship.
