Proud owner of a DC controller

[GS]

Just got a CMB-16D-QC DC controller to drive 12V LEDs.

I see I need DC input power, I'm guessing an outdoor rated transformer(land scape type).

I'm not sure how much power these LEDs draw. Is there a method to getting to the correct size 12V transformer?

Thanks in advance.

You need a 12 VDC power supply, not a 12VAC transformer.

Yes, you can convert it to DC but easier just to buy the proper power supply.

The transformer might be well over 12 Volts and might harm your LED's.

You need(must) know how much the LEDs draw.

I several power supplies from here powering a DC controllers and LED RGB light strips on our house.

I have PS1-150w-12 powering a DC controller and 10 rainbow floods.

I have my power supplies and DC cards mounted in a marine battery box.

I thought my landscape lighting was 12V dc not 12V ac. Learn something new every day. I did find a nice expensive outdoor power supply -

I like this price better. This is the kind of PS that most use for such a setup.

Put it and your DC board in a plastic enclosure similar to what the LOR PC controllers come in.
Mine looks similar to this.

I actually just ran out and took pics of my DC controller (the above pic was what I modeled this after), so will add here:

Thanks for the pics and link! I like the cost of your power supply, much better.

Here's a photo of my three DC cards and power supply mounted inside of a weather proof enclosure. 48 channels in one enclosure!

Can you reload that picture..its not showing, would love to see it.

Don,

Looks like the photo upload will have to wait until I get home on Christmas day - I can't get the file to upload from here (on a ship off the coast of Rio de Janeiro).
