Snow Posted December 26, 2011 Share Posted December 26, 2011 I have just started to assemble my 3 new controlers and I have realisd the following problem. I want to make some leaping arches, now each string of led lights that im using are rated at 24VAC. The CTB16 outpouts are 240VAC. Can I modify the channel output by using a 2.2K 20W resister in order to drop the output voltage to 24VAC or do I have to buy individual transformers for each string of Leds. Is there a 16 channel controller with 24VAC outputs?Many thanks in advance. I hope that everyone that came and saw your light displays were thrilled.

-klb- Posted December 26, 2011 Share Posted December 26, 2011 If the strings will run on 24VDC, you can use a CMB16QC controller, with a 24VDC power supply.Or, you can supply 240VAC to the right side, (9-16) so that the logic is powered up, then change the cord ends on the left side, (1-8) and feed it 24VAC, which it will correctly switch for the 24VAC load.
