Description

The BLD-TM04N-050 Emergency LED Driver is a cold-weather-rated 4W battery backup driver built to operate down to -20°C (-4°F), making it a strong fit for unheated warehouses, cold storage anterooms, parking structures, and other cold-climate commercial spaces. It pairs with an external lithium battery pack and keeps LED fixtures lit for at least 90 minutes during a power outage, automatically switching to emergency power when the AC supply is interrupted and returning to normal charging once power is restored. A double-click of the test switch during an outage cancels the emergency state early. It is UL Listed and built for indoor dry and damp locations.

• Cold-weather rated: operates in ambient temperatures from -20°C to 55°C (-4°F to 131°F) — suited for unheated or cold-climate installations where standard emergency drivers (typically rated no lower than 0°C to 5°C) are not rated to operate
• External lithium battery pack, connected to the driver by lead wires
• Emergency runtime: 1.5 hours (90 minutes)
• Output current and voltage: 80-133mA, 30-50V DC; output power 4W
• In emergency mode, double-clicking the test switch turns off the current emergency state
• Battery protections: overcharge, over-discharge, and short-circuit protection
• Batteries rated for 500 cycles of standard charge and discharge
• Universal input voltage: 100-277VAC, 50/60Hz; AC input current 80mA max; AC input power rating 5.0W max
• The connected AC LED driver’s output cannot exceed 50W or 1A
• Illuminated test switch with indicator light; red LED indicates charging
• Battery charging current: 250mA; charging time 24 hours
• Requires an unswitched AC power source on the same branch circuit as the AC LED driver
• Designed for dry and damp locations only — do not use outdoors, and do not mount near gas or electric heaters
• For use with grounded, UL Listed LED luminaires; the emergency driver must be enclosed by the LED luminaire and bonded to its grounding
• Manufacturer advises confirming product/system compatibility before final installation
• Customers are advised to recharge the driver for 24 hours every 6 months during storage
• RoHS compliant; CE marked
• 5-year limited warranty
• UL Listed (cULus, file E519224)

Applications

Emergency backup lighting for LED fixtures in cold-climate and unheated commercial and industrial interiors — unheated warehouses, cold storage anterooms, parking garages, loading docks, and other spaces where ambient temperatures can drop well below freezing.
