2.9.1 The 1…10 V dimming curve

The 1…10 V interface is defined in IEC 60929. In the control voltage

range of 3 V

to 10 V there is a largely linear relationship to the rela-

tive luminous flux. In the 1…10 V interface, a logarithmic response

(like the DALI units) is adjusted by a logarithmic potentiometer.

voltage

The control current in the 1…10 V interface drops with increasing

control voltage. Unlike the DALI interface, this does not therefore re-

main constant.
