9W External Emergency Battery Driver, 25–54V Output, 100–277VAC Input, 90+ Min Runtime

The 9-LP-Z-DEM-9W is an external emergency battery driver designed to maintain illumination during power outages in commercial and industrial lighting applications. It connects externally to compatible LED fixtures, providing a self-contained backup power solution for facilities requiring code-compliant emergency egress lighting. This driver delivers 9W of output power with a voltage output range of 25–54V DC, accepting input voltages from 100–277VAC to suit a wide range of electrical systems. It provides greater than 90 minutes of emergency runtime and operates across a temperature range of 0–60°C. The unit uses a LiFePO4 battery chemistry, which offers stable discharge characteristics and extended cycle life compared to conventional lead-acid alternatives. Full recharge is achieved within 24–48 hours following a discharge event.
