powering dc ssr for rgb strips

**chadowamsley** · 01-03-2014, 12:52 AM

Planning to use 8 RGB Waterproof Flexible Strips IP-68 60LEDs/m . Planning to use a renard plus 32 with 8 dc ssr from doyledexpress. I guess my question is, would I just grab a 12v 300 watt ps to power the dcssr? First time messing with dc so want to make sure they work and that I don't fry them.

Thanks

How long are the strips? They will pull about 1.2A per color per meter so you have to confirm you don't overload the DCSSRs.

The strips will be 13 feet each.

Since they are 12v dc I thought that the current would be 0.4A per meter per color, or 1.2A per meter of strip total.

Ah yeah - good point on that Jack.

So the 12v 300 watt ps would be to much for the 8 thirteen foot strips. Im just trying to make sure I dont fry anything, but trying to make sure while presales are going on. Im sure by setup time Ill have a good understanding on everything.

These 8 strips will be in a straight run, so the eighth strip and dcssr, will be close to 100 feet from the controller and ps.

Would I be better to use two controllers, 2 power smaller power supplies, and place one at each end ?

Chad,

I dont think you distance should not be too much of a problem. I did the same thing last year and was about 75 ft. from the controller with no issues. the one thing I did though was to keep the power closer, i put a smaller power supply and a dcssr in a cg500 case next to the strip and made sure the power was close. The signal gave me no problems but I think the power distance is what you mostly want to look at.

Brian and Jack correct me if Im wrong. I tend to miss things once in a while.

I have a pic of how I did them on my website if it will help you Chad.

Think Im making this more difficult than it really is. Thanks for the pictures on your webiste also.

So I could get something like http://www.ebay.com/itm/LCD-AC-Power...-/280869637229 , for each DC SSR Im running. That would give each SSR 6 amps, which is still ok even if I only use 3 - 4 meters of each strip. Cut the ends off the ps and wire it into the relay.

Thats what I did. Cheaper cost wise on power supplies to use them and I used 5A in each of mine. Plenty. Now the only difference is see is I used 30/m strips and I think you are using 60/m so just adjust your power accodingly and will work fine. The other thing you might want to consider is power injection on those. I had a 23' run and it kind of looked blah towards the end. should have done a power injection but with only 13 ft. you should be alright.
