A new DR4018 manual for the US English version is being finalized before release.
Here is what the manual says about powering the DR4018.
2.2 Technical specifications The connection terminals for power and signal (track voltage) are designed for a cross-section of 0.5 mm?.
The terminals for Out 1- 8 are designed for a cross-section of 0.34 mm?.
Each Out (1-8) consists of two outputs.
The terminal with the designation "C" is always the common pole and always carries (+) potential.
Terminals 1-18 are the respective outputs and always carry (-) potential.
The DR4018 switches to minus (-).
Protocol Max. Load per Out 1 - Out 8 = 2amps
Total current of all outputs 3 amps
Power supply 3A 12-18V DC? Recommended min. 12V DC 3A 12-18V AC
Note on power supply: When using "old" transformers (AC output), malfunctions may occur during operation under certain circumstances.? When using a transformer, it must also be noted that the output voltage of the transformer must be multiplied by 1.4 and therefore a higher voltage is applied to the output of the DR4018 than to the input (power). For this reason we generally recommend the use of switching power supplies with at least 12V (DC) output voltage (DC voltage) and 3A output power at maximum load of the outputs.
A CDU is only for a DC layout using ON/OFF or Momentary switches to prevent the turnout coils from getting hot and melting the plastic housing.
