Quantum Board dimming

[Snapples]

I recently purchased a quantum board 288 and when selecting a driver, I accidentally selected the variant without any voltage control. I know, stupid mistake. what are my options for dimming in this setup? would it be safe to run this board at full power? A heatsink is installed

Board rating: 2.8amp at 54v 150w

Which model number did you get exactly? I thought they only came in an A or B series, either of which are dimmable.

Nevermind, I can see in the data sheet a blank version with no dimming.

I just looked up how to do a diy led strip for my kitchen with an AC dimmer, and I think it would work for you, but it might be cheaper just to buy another driver.

Youd have to find a driver that is compatible with TRIAC dimmers, and converts AC power to an acceptable DC power voltage. Your driver will take 127-431 DC voltage. Then all you need to do is buy a wall dimmer at any hardware store.

The problem will be finding the TRIAC capable driver big enough for your board. Meanwell makes one in the PCD series, but the largest is capable of 60 watts.

So it would look like this...

120vac wall power ---->wall dimmer---->TRIAC Driver(converts AC to DC)------>your hlg 150h-54 driver(DC/DC)----->QB288

This is merely a suggestion, I could be wrong. I hope someone with actual electrical knowledge chimes in.

Hey Snapples!

I'm with Ted - I would try to return the driver and get one you can dim.

I have run 2800mA to these boards without issue - I ran a board at 54V on an HLG-600H-54 for a few hours and the thing was fine, but I can't guarantee it'll work for you too. Depends on ambient temperature, your model of heat sink, etc.

It would prooooooobably be alright to run at max, but if it were me, I'd get a dimmable driver just to have that control and better protection of your investment. Having the board run at 80°C and higher is not ideal either.
