I think they should just be wired in parallel.

I'm not sure what they included for actual connectors. I used a simple splice connector then shrink wrapped and taped the connections.

Blue and black are neutral. Brown and red are live. For the a.c. and dc sides respectively.

Assuming the boards are wired and installed on the sinks, it's just a matter of splicing the driver a.c. side to a power source (pronged outlet plug) and the dc side to the board itself.

To be continued....

Panels were mounted to the heat sinks like they should be wired in parallel.

I think they should just be wired in parallel.

Wire in series, wiring parallel could cause thermal run away.

I don't need them tonight so I will be looking for some info from Manf. tomorrow. I hope....LOL

Go to Horticulturelightingsolutions.com, on the site you'll find a how to video by ledgardner. Excellent tutorial.

I always use old appliance wires for my power source

A 3 pronged cord simply has a second ground wire.

Finally the dimmable switch is under the black little circle on your driver. Installing a drok meter to the DC side will give you an amp and wattage read out for various power levels.

I'm probably just speaking gibberish but once the manufacture sends your instructions feel free to reasd through them and post or pm if you have any other questions

They should be wired in parallel. You can get away with 3 of the 304s wired to that 240-2100b

 

[TheGreenYeti]

Reading everything you may be able to wire them in series since you have only two instead of 3 like I do.

 

[Pennywise]

HLG and Ledgardner recommend series.

Look what I found in a box today.

I got two different models to compare them. One is 2x304 led boards. The other is 2x312 led boards.

If anyone has wired these please chime in. I am waiting for some instructions from manf.

OK, you have two different drivers, a 240H-36a and a 240H-C2100a. The 36a is constant voltage, so you use that to drive the 312 boards in parallel. The C2100a is constant current and that will drive the 304 boards in parallel.

The 312 boards are 12s x 26p, so they run at 36 volts (nominally 12x3). The 240H-36 gives you 240 watts (120 watts each board)

The 304 boards are 38s x 8p, so they run at 114 volts (nominally 38x3). The 240H-C2100 gives you 250 watts (125 each board) at up to 119 volts, so you have to run them in parallel too. A C1050 would have let you run them in series at its 215 volt limit.

You'll need good heatsinks to run at 120 watts though, especially the 304s with the more tightly spaced diodes. I have the blue sinks and they heat up at 50 watts, not a lot but they're pretty hefty sinks.




[EDIT] !!! I changed this post - be sure to reread it. You have to run each pair in parallel with these drivers. That's not a big issue with just two boards. I wouldn't risk it with 4 or more.

JM, loving the double tents! I only have two seedlings and I am already plotting my second tent

Your plants are looking great!!

Thanks for supporting Mars tents. The pole is strong.

Been a little busy tonight have not gotten to the lights yet. Here are some update pics.

 

[JustMeds]

Had to make a quick run after work to pick this up, got it for $100 been used for one grow. Think it should be ok for the money while I play more with my home brew one.

Cool one controller to monitor the entire environment
