I am using 12VDC on the DR4018? for my N-Scale turnouts and they work just fine.
Per Digikeijs manual:
Maximum load per output is 2 amps, total output is 3 amps max.
12-18V DC
Recommendation 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.
