The TRC, excel systems, and another company (i forgot their name) drivers all come from Inventronics Company which is the manufacture of them. If you look at the part numbers of the drivers you will see they are the same but the first three letters.
Example:
TRC driver part number
TRC-200S070DT
Inventronics part number
EUC-200S070DT
If you read the spec sheet on all of them, they are exactly the same.
We had both a TRC and a Inventronics driver, opened them up and everything was exactly the same. Same wires including color, Same Components, and same case. The only difference was the sticker on the top middle of the driver.
I personally emailed Inventronics and they confirmed they manufacture all of these drivers and only change the sticker on them to fit the company's order.
I just emailed the local contact yesterday for both TRC and Inventronics, asked them for a stock count on some drivers. I got this reply "We do have these products on order and they should arrive by the end of May." from both companies.
I would encourage you to wait until these drivers are here, and also order a spare since they seem hit and miss to get them some times depending on the model number you are using.
But you don't need to take my word for it, I encourage you to do your own research to confirm the above. You can also read in the DIY forums since there is a lot of other people that have figured this out already.
As for me I am using the Intventronics because they are the same and easier to get than the TRC drivers. I would rather have 1 driver to power 80 LED's than 6 meanwell drivers. Also if you use the EUC or the TRC driver they are much easier to work with than the meanwells.
You can also talk to Bill at
http://www.reefledlights.com he sells the EUC drivers also since they are the same. He is just out of stock also.
