Description
We at TinMan recognize that the original design is still the best way to control engine speeds. Our objective is simple. Keep the original design and make improvements in other areas and upgrade the original design. Specifically, here is what we do when we recondition these units.
- Replace the original slow acting circuit breaker with a modern fast acting model.
- Eliminate the original rectifier and replace with a modern bridge unit that will enable the transformer to operate the bell circuits found in newer engines.
- Change the power cord with a 3-prong plug, to make phasing easier, and ground the exposed metal plate on the base. Why? Because the internal transformer is resting on 2 metal plates that are bolted to the outside metal base. While we have never had an issue with a problem with the internal transformer, it is possible and as a result send high voltage to the exposed metal plate. Grounding this plate will stop this very remote possibility, and also makes phasing with other transformers a breeze.
- Clean the exposed copper windings.
- Add switches to the front of the transformer to select the whistle control to operate both whistles and bells.
- Perform a final check of all operations, including documenting all features and capacities of the outputs on a “transformer report card” which is included with the transformer
Our ZW’s come to you with the latest technology circuit breakers, but despite our best efforts, while they work much faster than the original breakers, they are still too slow. Why? This transformer is designed to operate 4 trains and as such their breaker was very heavy. The solution is to add our circuit breaker kits which will blow instantly, in case of a derailment or other issues.
Like all our transformers this unit comes with a 2 year warranty,
