Power supply question
I'm in over my head, I built a train table for my son and I bought a kit to supply train sounds. The kit is battery powered, 2 AA batteries, but I want to connect it to the power supply from the model train transformer.
The sound kit requires a power supply of 2.4V to 6V. It says is has a standby current less than 1 uA and the operating current is 0.17 to 0.23 mA.
The model train transformer power pack that I want to connect it to is described as follows:
Power pack Input: 120V 50/60 Hz, Output: 17VDC 20VAC, Max output 7VA total. (AC is US Standard)
What do I need to do to run the train sound board on the model train power supply?
I'm a cop not an engineer, so dummy it down for me! Thanks!
