PaulDF Posted October 8, 2009 Share Posted October 8, 2009 Anyone know where I can get one of these? It is for a single 50w halogen lamp via a transformer so a 1A or greater version will do the job nicely. I have seen DMX versions but unfortunately the control board I need to run the single lamp from is analogue (NJD fade 4.) I can use an open PCB if these are available also.

pritch Posted October 8, 2009 Share Posted October 8, 2009 Velleman K8064? Having looked at the manual, you can adjust the control voltage range. Link to comment Share on other sites More sharing options...
PaulDF Posted October 8, 2009 Author Share Posted October 8, 2009 Spot on thanks, just ordered one. I'll have to practice my soldering skills too! Link to comment Share on other sites More sharing options...
dbuckley Posted October 9, 2009 Share Posted October 9, 2009 As a fellow Fade 4 owner, I'd hesitate to call it a "control board" ;) Link to comment Share on other sites More sharing options...
PaulDF Posted October 9, 2009 Author Share Posted October 9, 2009 You'll be glad to know it isn't for stage use, it is in use fixed to the wall behind the bar in the theatre foyer area ;) Link to comment Share on other sites More sharing options...
PaulDF Posted October 11, 2009 Author Share Posted October 11, 2009 I got the Velleman board and it works in a fashion, it works if I start with the fade 4 at zero and then bring it up slowly but if I power it up with the fade 4 on full (10v) then it makes the transformer hum and doesn't get to full brightness.Same if I push the switch up full brightness quickly.The velleman works on a PIC controller which is where I suspect the problem to lay.Any other ideas or solutions, I'm half tempted to just use an NJD 4 channel pack but seems a waste?

Joe White Posted October 13, 2009 Share Posted October 13, 2009 Sounds Like your using an electronic transformer. If you are get yourself an Iron core / Torroridal and there shouldn't be a problem. Joe Link to comment Share on other sites More sharing options...
ronknights Posted October 13, 2009 Share Posted October 13, 2009 Thomann do a nice little analog controlled 6.3a dimmer for about 25 quid. you have to provide and wire up all cables and plugs though!I'd post a link but I'm writing on my phone... its the cheapest one on the dimmers page.HTH Link to comment Share on other sites More sharing options...
Robin Pratt Posted October 13, 2009 Share Posted October 13, 2009 Probably overkill / over budget but how about the Anytronics Pro-dim 5? Spec suggests minimum 100w load but in my experience they're stable with 40w bulbs. Link to comment Share on other sites More sharing options...
PaulDF Posted October 13, 2009 Author Share Posted October 13, 2009 The transformer is a bog standard wire wound one, is the Botek one (from Thomann) controllable from an external source?The Anytronics Pro-dim is a little bit over budget unfortunately,Thanks.
