PSX vs OG, 3,2,1... FIGHT!

[Ed Kapuscinski]

I think I know the technical answer: the PSX has better adjustability, but are there any other reasons to choose it over the On-Guard?

I had a trio of OGs on the Windsor St layout and never had any problems, but I wouldn't say they were heavily battle tested.

Is there something I'm missing when it comes to choosing the cheaper option?

Ed, from what I have read, besides being unadjustably 4 amps (so not suitable for lower power DCC systems), the biggest difference is in the ability to handle in-rush currents due to keep-alives, sound decoders, and lighted passenger cars (both incandescent and LEDs with anti-flicker capacitors).

So, if you are using the OGs for small areas with low occupancy, they would probably work OK on a system that puts out more than 4 amps.

I use .5 or 1 A fuses.  They work, and now that I bought a bulk bag of them, I have not blown one in memory.  Adjust current as you need.

Awesome, thanks.

So really it comes down to a visible alert. Hmm...

Maybe I'll just do this as the inverse: rig up a nice pilot light on the fascia. If the light is out, there's a short. Easy peasy.
