HLG185H-20B wont go over 50 watt with Bridgelux eb gen 2 series

[wezzel]

I have a problem with my self-built LED.
I use the Mean well HLG-185H-20B with 15 x Bridgelux eb series gen 2 - 19.5 volts - 1400 ma max - 560mm

The driver draws no more than about 50 watts from the wall, no matter how many strips i connect to it.
I have used several other combinations 1, 2, 3, 4, 5 strips 15 strips
While when I turn 1 on it,.... it runs at 38 watts, so at max


I have connected them as shown at this website, only then everything on one side + & -

(from the website)



(how i did it, one side)



So in parallel, only + and - one side.



The lamp has the following specifications:

1 x Mean well HLG-185H-20B
10 x Bridgelux EB series 2.0 - BXEB-L0560Z-35E2000-C-B3 - 19.5 volts - 560 mm - 3500k
5 x Bridgelux EB series 2.0 - BXEB-L0560Z-50E2000-C-B3 - 19.5 volts - 560 mm - 5000K


Is the driver broken?, ore do i have the wrong one….. have really tried everything hard wire, soft wire, + & - one side, + one side – one side, ect


The only thing I do not use is the dim wire, so I did not connect a potentiometer

Who can help me?
I did it with translate, sorry for mistakes in the text.

Thanks!


See here results;


1 strip 38 watt from the wall:

1 x Running



1 x Wiring



1 x = 38 Watt





2 Strips 52 watt from the wall

2 x Running



2 x Wiring



2 x = 52 Watt






15 x Running - 10 x 3500k & 5 x 5000k



15 x wiring



Parallel only + and - on one side

15 x = 49 watt




Thanks Again!

What is the voltage the driver is putting out. I just sent back a 600h 48b bc it only put on 40v.

What did you do with your dimmer wires? Are they spliced together?

Did it measure 40V without any load on it or is this with the lights hooked up?

Hooked up to chilled pucks.

this was my first thought.. them touching making it only supply minimum..

Sory for the late response, I had to buy a multimeter

the problem is that the more strips I connect to it, the more the voltage goes down.
see pictures

1 2 3 strips

1 strip 20.12 volt
2 strips 19.79 volt
3 strips 19.37 volt

15 strips

10 strips 3500k & 5 strips 5000k 18.49 volt

amps on 15 strips

1 strip 3500k 099.8 mA
1 strip 5000k 0.137 A, so 137.0 mA

10 strips 3500k & 5 strips 5000k 2.24 A

This is why the lamp only draws 50 watts from the wall.
The voltage is too low.

The driver should still just give 20 volts 9.2 amps right?




I had contact with digikey today. they are going to send me a new one.
If this does the same, the tutorial on this site is not correct.
You will then have to use a 24 volt for the bridgelux eb gene 2 series.

Does anyone use the 20b driver for the bridgelux eb gene 2 series 19.5 volts?

I use the 20A without problem on Eb gen2 builds.

How do you have the strips wired when you were doing all this testing?

[wezzel]

Received new driver from digikey today.

Problem has been solved, it was the driver.

Now pulls around 200 watts from the wall.
And with potentiometer from 6 to 200 watts.

This is because the potentiometer is unfortunately not exactly 100k,

Nice! It's pretty rare for those Mean Well drivers to fail. Glad you're sorted
