This ready-for-use resistor from the Tridonic Accessories series is used to set a 225mA output current value in LED driver series featuring the I-SELECT 2 interface specifically the PRE and EXC series (this resistor is not compatible with the I-SELECT generation 1). A base isolated resistor with a 0.25 Watt resistor power and compact design measuring 5.5x21x4.5mm when this resistor is used beyond the specified range the output current will be automatically set to the minimum value respective to when the resistor value is too big.
