If dimming function is not used, 12V(yellow) and 1-10V(purple)wire must be connected together.
Primary to Secondary Isolation test not to be carried on power supply.
Load Voltage must be maintained above minimum voltage. See models for voltage range.
Dimming range is 10%-100%
Dimming Signal Voltage should be above 1V for linear dimming control.
See Dimming Implementation diagrams for various dimming methods.
