Review: Had to do some research but all worked out well. I would buy again from this seller - was a little different than the part number I had ordered. It had a different wire set up then the one I was replacing but after a little research found out that all I had to do was connect the two reds and two whites together and it worked fine. would have been nice to have some sort of direction in package to explain the difference. But in the end all worked well and I am happy with the purchase.
Review: 1st one defective. - I purchased as a exact replacement for my George Kovacs 6 halogen rail track lighting. First off the transformer did not kick off right away. when it did there was buzzing coming from it and the base unite got much warmer then the original factory one. I put it through the test of using it install in the fixtuer, on and off for a day. after a single 12 hour run time, it went out and never worked again. I returned it and re-ordered a replacement. The Replacement had no buzzing and seems to be working as expected from how the original factory one worked. PS) when contacting the seller for a RMA, I was sent troubleshooting information with directions of how the wiring should be but the information did not match or any wiring that obtained to my transformer. They did not take the time I guess to see what transformer I purchased from them. in short the info was useless and being how frustrating it can be with trying to work with a 3rd party seller through desertcart with back and forth messages, I did bother to see if I can get correct troubleshooting information. I was given authorization to return the defective transformer but surprised to be contadiced if the transformer worked or not and my installation of it. The testing I put on the transformer purchased was much longer then there standard test they required,. (testing information the company included with there directions for installation) Be advised a refund under the 30 day policy may be difficult to get, just saying. I had some difficulty but got a refund for the first defective transformer after a few e-mail back and forth with the seller. When deciding to purchased this, did notice there were many issues from other purchases of problems and low ratings. I did take the negative reviews into consideration but I also did found that there are not many suppliers that sell this transformer by itself and George Kovacs discontinued making halogen rail systems and do not supply parts for them. It was a decision to try to repair what was already up and across my ceiling, or buy another track light system of this type for a lot more money.

## Questions & Answers

**Q: It appears this has two outputs can I parallel both to the same fixture.**
A: The WH-2301S comes with two sets of output wires (2  115W circuits) for a total of 230W. If you only want two output wires instead of four, you will need to combine the wires. This is done by combining the Red to Red and the White to White. The unit is shipped with these wires taped together with electrical tape. So this unit can either be used for two separate circuits at 115W each or can be paralleled together for a single 230W circuit which is what the original (older) unit was rated for - see this webpage for a drawing if it helps:   http://www.doityourself.com/forum/electrical-ac-dc/519244-wang-house-model-wh-2301s-230watt-12v-transformer.html

**Q: Received unit without the "caution-do no throw away" paper included in box" on how to reset the unit.Where do I find? No answer on company customer ph**
A: The unit came in an evelope with no instructions or papers.

**Q: can I use this transformer with LED lights?**
A: It has 50W Min. Wattage rate to work. So could use it if Total (LED) loading from it be over this Min. Wattage.

**Q: Will this work with a dimmer installed ahead of the transformer? If now is there a "surface-mount button dimmer" that would work?**
A: I believe that dimmer has to be installed after transformer. The input should be constant and output you can dim. Otherwise it won't work at all.

### ⭐⭐ Intermittently dimming and a very noxious smell ?
*by A***M on February 12, 2016*

160212 orig post... Not sure what is happening with the DesignClassic rail kit track lite (with 5 hanging pendants) we purchase and then replaced the transformer with this WH-2301S purchased about 1yr ago. The lamp started intermittently dimming and a very noxious smell started coming from the junction box. We are trying to determine what is happening and will update this post asap. If you have any ideas, please let us know. Thanks. 160921 update... Returned transformer, got refund, and after several email attempts to request reason for symptoms, got vendor message that transformer was ok, but they did not send it back to reinstall as their return policy indicated. If got back would try to get another local opinion b4 try reinstall, but due to no return couldnt followup. Am still working on where to buy new transformer.
