Description

The WSD-170YT08W-AC Emergency LED Driver is an 8W battery backup driver with a patent-pending, ultra-slim form factor purpose-built for ultra-thin back-lit panel lights. Its long, narrow profile wires directly into the AC input of the LED driver, needs no flex conduit or connector, and works with CCT-selectable fixtures. It delivers constant power for a full 90-minute runtime and includes automatic monthly and annual self-testing. It is UL Listed to UL924 and CSA C22.2 No.141 for both factory and field installation.

• Patent design ideal for ultra-thin back-lit panel lights — easy to install and fix
• Simple wiring: connects directly to the AC input of the LED driver; suitable for CCT-selectable lighting fixtures
• No flex conduit or connector needed — slim, low-profile installation
• Constant output power; built-in lithium battery
• 12V auxiliary source available
• Protections: input over-current, output over-charge, output over-discharge, and output short-circuit protection
• Output voltage: 170V DC; emergency power 8W
• Universal input voltage: 100-347V AC, 50/60Hz; input current 100mA max; input power 6W max
• The connected AC LED driver’s output cannot exceed 150W or 4A
• Emergency runtime: 90 minutes minimum; recharge time 24 hours
• Automatic self-test: a 30-second discharge test monthly and a full 90-minute discharge test annually; the unit returns to normal operation automatically if the self-test passes, and the indicator turns yellow if it detects a problem
• Skinny Film test switch with 3-color indicator (Green flashing = charging, Green on = full charge, Red on = discharging/emergency mode, Red flashing = low battery, Yellow = error); 7.87″ (200mm) lead
• Mandatory 0-10V dimming interconnect: the emergency driver’s Dim+ (Blue) and Dim- (Yellow) wires must connect to the LED driver’s DIM+ and DIM- terminals — required whenever the connected 0-10V LED driver’s input power is 60W or less, whether or not an external 0-10V dimmer or DC12V sensor is also used
• Optional DC12V sensor input
• Ambient temperature: 5°C to 50°C (41°F to 122°F)
• Sealed Li-ion battery; please charge continuously for >24 hours on first use to activate the full battery cells; recharge for 24 hours every 6 months during storage (maximum 1-year shelf life before recharge is required to avoid battery damage, not covered under warranty)
• 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
• Standards: UL924, CSA C22.2 No.141; complies with the NFPA 101 Life Safety Code; California Energy Commission (CEC) Title 20 Compliant, with BC certification
• Contains a rechargeable Li-ion battery — must be recycled or disposed of properly
• UL Listed (cULus, file E530386)

Applications

Emergency backup power for 0-10V dimmable, ultra-thin back-lit LED panel lights in offices, healthcare facilities, retail, and other commercial interiors where a slim, low-profile emergency driver is needed.
