Compatibility between LED module and LED Driver
c
13 / 63
There are two stages involved in the check for compatibility between the LED module and the LED Driver.
Comparison of data sheet values with a 5-point guideline
Different values for the two devices need to be considered when comparing the data sheets. The following table shows which values
are involved and which requirements they must meet.
