Ratings for CTB16PC capacity

[gizmomkr]

I just finished assembly of my forst board and was wondering whats the TRU OFFICIAL word on amps per chanel ?

The printed manual that came with my box of parts says 1 amp with low power heat sinks,

The PDF posted to the LOR page shows it as 4. Most of the posts I have seen say 1-2

I just want a sold number to go off. I'm sure it depends alot on ambient temp, airflow in your enclosure and how long you dimm a given load.

I get the goneral idea is : Dont let the Traic overheat - I just want to know whats safe.

Thanks.

Here is a summary for the various controllers, with the 2 most common controllers highlighted. 8A per channel if using regular high power heat sinks. However, 15A per 8 channel bank (1-8, 9-16). Therefore, if you use 8A on channel #1, then you only have 7A left to use between the remaining 7 channels in that bank (ch 2-8).





Here is a summary of the CTB16PC controller specifically. I think you confusion comes with the type of heat sinks used.

Thanks.

With the low power heatsinks we recommend no more than 8 amps per bank of 8 channels with a max on one channel of 4 amps.

It was important enough to say it twice
