YD7001 Power Supply Voltage


 

I hope I am doing something wrong again.....
I connected a 15v DC power supply (Meanwell 15P1J) to the YD7001. The 15v DC is confirmed by my multimeter.

However in the YD7001 app (Build 59) the power supply window shows 19.0v and the track voltage window shows 17.8v.
My RRampMeter from DCC Specialties shows 14.1 volts on the track which is roughly what I expected.

I do recall buying a DR5000 with a 19v power supply initially since that was all there was available, but bought a 15v power supply rather than the supplied one as I run HO and not O scale. Is that a clue?


 

This is the same for me. I was told yesterday in the Facebookgroup that this is "by design" for the YD7001.


The new YD7100 will show the correct voltage.


 

Indeed, as the 7001 FW is a backport of the 7100. But the YD7001 lacks the measurement hardware.

in a couple of weeks I will publish a hardware patch to the 7001 PCB that enables Voltage measurements.
