EM-EMS Series
Split Emergency Driver
The EM-EMS series emergency LED driver is for field and factory installation that allows any Sunled 0-10V dimmable fixture to be used for both normal and emergency operation.
The unit contains a battery charger and inverter that operates a load of 8W or 18W with constant power at a rated output voltage of 170VDC. The patented constant power circuitry of the module maintains uninterrupted illumination levels during power failure
Product Code

NOTES
¹ The emergency driver is not compatible with non-dimmable fixtures when the driver wattages is less than the fixture wattage.
Features
- Constant power output in emergency mode
- Split two piece design with smaller dimensions for integral enclosures
- Self-sensing output voltage circuitry maximises product compatibility
- High temperature recyclable lithium battery technology enables significantly decreased enclosure size and longer operational life
- Quick connect junction box on driver side reduces installation time
Self Diagnostic
The integrated self-diagnostic circuitry will automatically conduct 1 monthly 30 second and annual 90 minute tests to verify proper emergency capability per life safety code requirements NFPA 101 Life Safety Code outlines the following schedule:
Monthly
During AC mode, the system conducts a 30s self discharge test of the emergency LED driver every 30 days and automatically restores to normal charging after full discharge
During AC mode, the system conducts a 30s self discharge test of the emergency LED driver every 30 days and automatically restores to normal charging after full discharge
Annually
During AC mode, the system conducts a 90 minute self discharge test of the emergency led driver every 365 days and automatically restores to normal charging after 30 seconds discharge
Operation
Normal Supply
During normal AC supply conditions the LED driver load will operate as usual and emergency driver remains in charging mode
During normal AC supply conditions the LED driver load will operate as usual and emergency driver remains in charging mode
Emergency Mode
When AC power fails the driver automatically switches to emergency mode, keeping the LED load illuminated at a reduced lumen output for a minimum of 90 minutes. During this time, the indicator will flash slowly (light on for 2 seconds, off for 2 seconds). When AC power is restored, it will return to charging mode and the indicator light remains on
