5.1. Adjustable output current
5.1.1. Description
If the EM converterLED ST switches to emergency operation in case of a power failure, the device will detect the forward voltage of
the connected LED modules and set the correct LED current. Setting a constant output power ensures maximum light output in
emergency mode for the specified operating time.
An EM converterLED ST with approx. 3, 4 or 5 watts output power operates the connected LED modules with the output power
mentioned before. For this purpose, the device detects the connected LED forward voltage, and adjusts the LED forward current to
the appropriate value, resulting in an output power of approx. 3, 4 or 5 watts.

NOTICE
At the lowest range of permissible forward voltage, the efficiency may be slightly lower. In this case the output power is also
slightly lower.
