Modern Era Transformer

If you don't need a bell button, just get a cheap 1033 and put 3 amp reset-able circuit breaker on the output to your test track and add a TVS diode to the track outputs.

I am using an ATLAS 80 watt transformer that came with a starter set. It's perfect for my bench. It has Whistle & Bell buttons, and I added TVS protection to the output and a small 3 amp breaker inline to the test track.

The breaker is optional, TVS protection is mandatory. The age/era of the transformer is irrelevant.

Any suggestions for a modern era transformer (with updated circuit breaker)?  Don't need a lot of power; just need it to test run modern era locomotives.  Thanks.  Tom LoPresti

For a "modern era transformer", I'd look at the MTH Z-500, 750 or 1000 depending on your power needs (50, 75 and 100 watts) or wait for the "new and improved" Lionel CW-80 (80 watts) 6-1908080 scheduled to be shipped in September of 2022 according to their website.

"The breaker is optional, TVS protection is mandatory."

Why is the breaker optional, say with a postwar transformer?  Or are you only referring to transformers currently being made? Seriously appreciate your expertise, by the way.

The new CW80 already shipped, I already did testing and comparison of the new design. Dealers have or had them. If completely sold out, OK, then waiting on another batch?

Note, personally, I'm not recommending it over an MTH Z series, just noting that I tested the design and did comparisons and the new design is better than the old design.

My notes, pictures and videos of the new CW80 are multiple replies starting with this one https://ogrforum.com/...9#161631098285667179

I have a z500 and it’s yours for $65.

Most postwar transformers have circuit overload protection via a breaker already, a few 25w models do not(they solely rely on heat dissipation). There are no breakers designed for transient voltage suppression which is a voltage issue, not current. The voltage spikes are what pose danger to modern onboard electronics, breakers are not in place to protect locomotives or electronics from over-voltage.

For anyone looking for a simple, all in one solution for overcurrent and voltage spike protection Dallee Electronics sells them. They are available in 3A, 5A, 8A, 10A & 12A ratings.
