EM converterLED
5.4 LED Driver compatibility
The EM converterLED emergency unit use 3 pole technology and is compa-
tible with most LED Drivers on the market, however it is important to check
that the rating of the LED Driver does not exceed the values specified below:
• The max. allowed output current rating of the associated LED Driver is
2.4 A peak (current rating of switching relays of EM converterLED)
• The max. allowed inrush current rating of the associated LED Driver is
60 A peak for 1 ms or 84 A for 255 μs (inrush current rating of switching
relay of EM converterLED)
• The max. allowed output voltage of the associated LED Driver applied to
the EM converterLED output is 450V (voltage withstand between adja-
cent contact of the single switching relay of the EM converterLED)
• The max. allowed LED load of the associated LED Driver is 150 W in
operation. The load must be an LED module.
Check compatibility with short function tests (duration of several seconds).

Usage duration link
Emergency lighting LED Driver supplied with duration link in 3 hours
position.
The position of the link will only be read on first power up. If it is changed
afterwards both the battery and mains supply must be disconnected for
10 seconds to enable the EM converterLED to read the new link position on
reconnection of the battery and mains. It will lead to a false battery failure
indication if the link is changed after installation without this reset.
