Part of the Tridonic Accessories for LED series this is a compact blue ready-for-use resistor used to set the output current value to 1250mA in LED driver series featuring the I-SELECT 2 interface alongside PRE and EXC driver series (this resistor plug is not compatible with those featuring the I-SELECT generation 1 interface). When using this resistor at a value beyond the specified range the output current will automatically be set to the minimum value (if the resistor value is too large) respectively to the maximum value (resistor value is too small).
