The WSD-300YM Emergency LED Driver is a self-testing battery backup driver with a split design — an external LiFePO4 battery pack connects to the driver for flexible installation in narrow spaces. Available in 8W and 25W output tiers, it automatically switches to emergency power during an outage and runs a monthly 30-second and annual 90-minute self-test if enabled. The long-life LiFePO4 chemistry is rated for 2000 charge/discharge cycles and a wider operating temperature range than standard Li-ion emergency drivers. It is UL Listed to UL924 for both factory and field installation and built for indoor dry and damp locations.
Emergency backup lighting for LED fixtures in commercial and industrial interiors, especially installations needing a longer-cycle-life battery or a wider operating temperature range than a standard emergency driver.
