Description

The WSD-EMS15W27-LT20 Cold Pack Emergency LED Driver is a 15W emergency battery backup with a physically separate battery case, giving installers flexibility to mount the driver and battery independently. Its cold-rated Li-ion battery is built to operate across an extreme -20°C to +60°C (-4°F to 140°F) range, making it a fit for unheated or cold storage environments where standard emergency drivers aren’t rated. It automatically switches LED fixtures to emergency power during an outage and is UL Listed to UL924 for both factory and field installation.
