Qb132 diy

So I bought a 4 pack of the qb132 boards with an hlg-240h-c1750a driver.
Got them wired in series as the hlg website recommends with this driver and I was told I would not need a heat sink but this light keeps kicking my breaker.
I put a fan on the top of the frame blowing at the driver and it stopped it for a week or so and ran fine till today. Now it stays cool to the touch and still kicks the breaker where as before you could only keep your hand on it for a moment before it was to hot.

I have checked the wiring over and over and even took the time to print out some parts to put the frame together so no metal was touching thinking that maybe something was shorting out. I have also dimmed the driver down some only thing that has done was take more time between kicks.

I was running a 600 watt hps in this room with a portable ac just fine. but with this led things just dont want to run.

I have a small space heater in the room to make sure temps stay in the low 80s on cool days and a 6 inch exhaust fan. I have also had to run a dehumidifier in there this time without the ac running.

Im not sure what to do at this point. I am considering just tossing this whole set up in the trash and buying another hps set up since my 600 watt is in use for other things now

Here are some pics of it if anything else is needed for advice here let me know

ps. this is for a small tent the 600 watt hps was over kill. i had it running at 75% the tent is 32x32x60 inches

Couple thoughts

I run 6 of those in my 4x4, works great
Each BD maxes at 75w and 2100ma, so that driver will in no way come close to maxing them out

Does each BD light up
In series or parallel

I run in series

Be sure your wires are correct to. The brown, blue, cornfused me at 1stSeries2_grande.png

The first pic is the wire going into the driver. Each board lights up and they are wired in series. I pulled all wires and rewired it just to make sure I didnt cross something somewhere and have the same results.
I did leave the wires long on the back side since I changed the layout of the light (made it smaller)

Sometimes when breakers get old they trip before they should.
Is the circuit on a GFI breaker?
It could even be simple over loaded now...more then 1 room can be connected to the same breaker...add any fans or AC to the home?
If you run just the light and no extra equipment like the dehumidifier, heater and or AC...does it still trip?

Oh I see...

If it's kicking a breaker, it must be a wireing issues

I'd assume it's your power cord, be sure that's correct

I've never seen, ever, a bad mean well drive die that fast, or at all

Nothing new was added. the breaker is connected to 2 rooms (part of them anyway. ceiling light in one of the rooms and the outlets in another)
The dehumidifier is the portable ac that was running with the 600 watt hps not it is set to dehumidify only (it has a few different settings)

Try disconnecting all the light panels and just have the driver by itself...cover the output wires on the driver with tape or something so they can't touch anything or each other and plug JUST the driver into the wall socket...does it still trip the breaker?

I will give it a shot and let you know. It takes a bit of time for it to kick it off normally an hour or so after its been running

I doubt there's a problem with the light. It's probably the heater and dehumidifier, plus the fan and light on one 15 amp circuit.
What's the wattage or amps of the heater and dehumidifier? Electric heaters can draw a lot of power, 1500w or 12.5 amps is common and a dehumidifier might be around 5 amps, the light should be around 2.5 amps at max power.

I thought it might be one of them also when I first put this light in there so I ran it till it kicked while it was the only thing on.

And when it trips...check right away to see if the breaker is warm/hot or same temp as the others in the panel.

still sitting there just fine after all this time.

In that room I have everything running right now. the heater, the dehumidifier and a 100watt hlg led. it is still cool to the touch (dont feel like its even plugged in)

Hmm, it sounds like you've issolated the problem to a failed driver. I'd speculate that it's drawing a big surge, it would be smoking hot if it were drawing high amperage continuously. You could try it on another circuit to verify, but don't leave it unattended! I'd contact the seller or Meanwell.
