EM powerLED
5.5 Output current setting
Output current can be set by connecting a resistor between the 2 “I set” termi-
nals. Relationship between output current and resistor value can be found at
the table “Specific technical data”. Resistor values specified from standardised
resistor value ranges.
Resistor value tolerance has to be ≤ 1 %.
Resistor power has to be ≥ 0.1 W.
Resistor detection at each start.
Change of the resistor value during the operation will be not considered.
Resistors for the main output current values can be ordered from Tridonic (see
accessories).

5.4 Typ. LED current/voltage characteristics
The LED current in emergency mode is automatically adjusted by the EM powerLED module based on the total forward voltage of
the LED modules connected and the associated battery.
Note: LED peak current is measured at the max. battery discharge current.
