How many watts...

[Therrion]

I have a https://www.rapidled.com/mean-well-hlg-320h-c2100b/ wired in series to 3 x https://www.rapidled.com/chilled-logic-puck-v3/. I'm also using a PWM dimmer. I was wondering how many watts each puck pulling at 100% with this set up, so I know how far I need to dim.

Sorry. No help on wattage question.

But....When it comes to knowing where you are on the dimmer these are great. Search "drok" on Amazon. ( my voltage exceeds the meter limit but it still works fine for watts and amps.)

46v x 2.1amps = 96.6w per puck.
Might be slightly higher due to voltage increase at that current.

If you run with the dimmerleads open then even a bit more, about 10% extra current.

I would do that, but I have 24 of the chilled logic pucks for a 10' x 5' scrog . I have to dim them or I would be blinded working around my plants. I hate wearing those grow light glasses.

For max power, you can install a 10K resistor in series with the dimmer pot.

It's a PWM, I didn't think they worked by resistance like pots.

Kill-a-watt dealio could help confirm actual volt and watt differences for different scenarios.

How did you wire that? The instructions are shit.

I hate when I need to lift the LEDs above eye level... that streak of dots pattern it burns is plenty annoying.

On mine.

The led driver dimmer wires are connected to the inner two connections on the drok.

The droks outer two connections are connected in line with the leds.

Thank you!

That's hilarious.
You win the most useless suggestion award.

I know, but be nice lol.

Wow.. do NOT take advice from eatled he has absolutely 0 clue. What @1212ham said is correct.

So YOU believe adding a resistor will give you more power than running an open circuit?

From what I've heard running with a less-than-max wattage actually increases efficiency, no clue if that applies here, just throwing that out there. Maybe not more power, but more efficient.

 

[ChiefRunningPhist]

So YOU believe adding a 10kΩ resistor will give you more power than running only a 100kΩ dimmer POT that's probably only ~97kΩ?

Yep. Follow me and you might learn something. I've been teaching eatled all week.

I might, but I can't see how physically adding a material link in the mechanical chain could increase conductivity, without coating the entire housing in a more conductive substance than originally built.

Not that I'm not often wrong... or kind of high and took the comment as a joke cause it made me laugh. I am tired and I'll check back in the morning to see if I can learn anything neat about pots and resistors.

It decreases conductivity

The higher the resistance the greater the current flow... Dude said to add 10kΩ to a dimmer POT to make sure to get all of the driver because most dimmer POTs are a few % off and the drivers normally have a little extra to go..
