40W Emergency LED Driver, 170Vdc Output, 100-347VAC Input, 90-Min Backup

The D-EM-40W is an emergency LED driver that maintains illumination during power outages in commercial and industrial LED fixtures. It accepts universal input voltage of 100-347VAC at 50/60Hz and delivers 170Vdc output at 460mA, and operates with 0-10V dimmable LED fixtures when a dimmer switch is used. Typical applications include linear highbay wall plate installations. Emergency runtime is 90 minutes from a built-in lithium-ion battery rated for 500 standard charge and discharge cycles, with 500mA charging current and a 24-hour recharge time. Battery protections cover overcharge, over-discharge and short circuit. AC input current is 200mA maximum with a 15W AC input power rating. The silicone-potted enclosure is rated IP65 for an ambient range of 5C to 50C (41F to 122F), measures 288 x 77.3 x 46.5mm with a 271.5mm mounting center distance, and integrates an illuminated test switch and charging indicator. The driver is UL listed under file E493915 and RoHS compliant, and carries a 5-year full warranty.
