Controller advice please
« on: November 29, 2017, 09:15:41 pm »
Hi forum don’t know if this has been answered before but I have an HM2000 controller and a gauge master twin track controller which one would be more suitable to run my trains as some of my Kato trains fade out at higher speeds with the HM2000 I don’t really want to buy a new controller any advice would as always be gratefully received thanks in advance

What do you mean by "fade out" ?  Both of those controller should be able to power your models.   I think the HM2000 is a PWM controller, not sure about the Gaugemaster - but if the latter is pure DC you might find it kinder to the motors.

What I mean by fade out is that it is a brand new Kato TGV I ran it in but when I hooked up the entire train and run it at slow speed it was ok but when I I turned up the power the train stopped but came alright when I restarted it

I don't have a particularly high opinion of the HM2000. I used one to test/run in a few 00 locos, and the level of control was not good even for them. I didn't even consider it for N gauge.

Might you have answered your own question there Andy? If your Katos perform OK using the Gaugemaster, there you go. :beers:

I don’t know because the layout is hooked into HM2000 have not tried Gaugemaster was basically looking for advice if I should change over controller because I used the HM for my OO layout and was not sure if it was too powerful

Similar question/discussion running on the NGF Facebook page at the moment.
A controller can't be "too powerful", at least not in terms of amps.  A motor draws the current it needs, a controller can't "force more into it".   If the output voltage goes too high that's another matter, but both controllers you mention are intended for what are nominally 12V model railway systems.

Where I might be concerned is whether the overload cut-out on the HM2000 might be tuned too high as it's marketed for OO gauge models which draw more current than N.  That said, I'm surprised at your comment that your Kato TGV seems to cut out at higher speeds. Kato motors are usually pretty efficient low current draw and should be well below the overload threshold of the HM2000. 

It does sound like an overload cut-out, perhaps there is a fault in the TGV - could even be in the unpowered car if that has lights?   Are you sure it's not a trackwork short,  are all your other locos running ok?

It could be a short as it is a second hand layout I bought so that is possible but I have changed onto the gauge master controller and the glitch with the TGV has not appeared so I think I will stay with this controller.

Many thanks for all the advice and help it has been invaluable
