Greybloke Posted December 24, 2018 Share Posted December 24, 2018 Hello Merry Christmas everyone. I have a question if anyone can help. I have a SR S15 Class (R3327) fitted with TTS Sound, can anyone tell how much current it draws. Thanks Garry Link to comment Share on other sites More sharing options...
96RAF Posted December 24, 2018 Share Posted December 24, 2018 Unless you have a DCC controller that indicates current, then to perform a stall check you have to remove your decoder, fit a blanking plate and carry out the check on DC.Rob Link to comment Share on other sites More sharing options...
Fishmanoz Posted December 24, 2018 Share Posted December 24, 2018 Until you do the stall test to be sure, chances are it is drawing around 250mA flat out with the sound up. This is typical for modern locos. Link to comment Share on other sites More sharing options...
96RAF Posted December 25, 2018 Share Posted December 25, 2018 The TTS decoder spec (see the user manual) shows a max total limit of 800mA so if its working well then your current current draw is obviously less than that, as Fishy says probably much lower than the max limit.Rob Link to comment Share on other sites More sharing options...
