This kind of question usually appears when there is an operating problem, and people start looking for some kind of fault.

 

 

I have only asked one question at the start of this post - “Please can someone with the same controller confirm if they get similar fluctuations?”

As I said, I have intermittent (and strange/random) poor running (and a dead ESU decoder). I deliberately didn’t list any problem examples, because I didn’t want to muddy the water and take the focus from my question.

Whilst nobody has categorically confirmed my readings are normal, some have suggested that the readings I see are probably ok and I’m inclined to agree, so I’ll close the topic.

My bad. 18V not 19.

I have attached a photo of my z21 controller and the 18V 36W Roco PSU it came with.
 

I use the 19VDC PSU that came with the z21 Start. As I said, I get the same result when I tried using a Hornby 19VDC PSU. 

I don’t know for certain if either are regulated or not. There’s nothing on the labels to indicate as such. 

Thanks Nigel.

Thank you Iain and John, but I'm wondering if the video is actually playing for you. I have to click on it to get it to play.

The Electricity on Main Track reading fluctuates between 55mA and 121mA and the bottom two voltage readings fluctuate between 17.7V and 18.1V. It was recorded whilst running a loco pulling four carriages arround a radius 3 elongated loop.

Thanks

Hi,

I have attached a short video showing my Z21 app displaying fluctuating power values on my White z21 Start. 

Please can someone with the same controller confirm if they get similar fluctuations?

I have tried another 19VDC PSU and I get the same fluctuations. 

I also see the same fluctuating values using the Z21 Maintenance Tool on my PC. 

I have recently been experiencing intermittent slow and stuttering running of different locos at different times, which I’m trying to pin down. 

Cheers,

David
