Improper voltages will cause unnecessary heat in the module. For internal temperatures >= 80°C the
module will power off (reversible).
Constant current LEDs must be connected in series. Depending on the number of LEDs used the
recommended voltage for the power supply is (these are guidance values depending on the LEDs
used):
1 RGB-Group - abt. 7 - 7.5
Volt Power supply (abt. 7 Volt is the minimum operating voltage of
2 RGB-Groups - abt. 7.5 - 9
Volt Power supply electronics)
3 RGB-Groups - abt. 10 - 13
Volt Power supply
4 RGB-Groups - abt. 12 - 15

5 RGB-Groups - abt. 15 - 18

The example above uses 3 LEDs. A 4-wire cable is used, in which one wire is a simple pass-through
for the .
ChromoFlex modules will not emit high frequency signals, even for longer lines. Unlike many
electronic transformers for halogen lamps cable lengths of 10 metres are unproblematic, if the
calculation above is considered
Hint: Copper has a resistance of about 0.02 Ohms per metre for a cable cross section of 1mm².
