a little help

[boyd crowder]

hey riu, i have some issues im trying to work through
maybe i can get some suggestions?

im building some flower lights and some veg lights
1st up is my flower system
its based on samsung lm562a 2' strips
they are 450ma @ 24.7 Vf
and im attempting to fire up a rig i built yesterday


running these parallel , hooked up the hlg150h 24b to ten strips and - nothing
mightve burnt em up idk
i then hooked up another set of these (i bought 40+, they were super cheap) around 14 in series , still no love
how do i get these guys to fire on this driver?
do i have the wrong driver for this application?

Datasheet for LT-F562A says 1.35 amps at 24.7V.

Also, are the three double row strips connected?
What are exact part numbers of both types of strips?
It looks like you have 400 watts+ of strips on a 150 watt driver.

 

[Randomblame]

It's a constant voltage driver you need to wire in parallel. But it's not possible to run the double row strips together with the 1footers on this specific driver. You need an HLG-185H-C700(200w) or an HLG-120H-C700(150w).

But you'll get uneven brightness when you run all the strips with the same current. One could balance the circuit with series/parallel wiring for an 48V circuit but this is even more complicated.

One tip! Use only strips with the same voltage and power requirements, which makes it much easier. And the link to the LEDgardeners website is worth gold.!

um - hey the big strips run on a seperate driver - those arent on this mini strip circuit
so
its 10 strips - 5 x 3500k + 5x 4000k
im trying to get these to run on this driver, but not understanding why they arent firing on a sinple 150w cv driver, should i use another 5 strips in this design for that one driver?

iread ledgardeners post earlier this morning - its dope
but i need to figure out how to get these 450ma 24.7v 24up strips to run on these 150 w drivers today
thanks everyopne for your input so far!

A DVOM will show you where the problem lies. Power up the rig and check voltages.

ok, well anyone else care to add to this thread?

Where did you get the figure 450ma?
What is the part number of your strips?
24up strips?
Do you have a volt meter?

 

[JavaCo]

What do you have hooked to the dim wires? unhook them and leave them open and see if it will fire up.

 

[1212ham]

Normally/often the opposing terminals are interconnected on a terminal strip. I bet you have a short circuit by having positive on one side and neg. on the other.

[VegasWinner]

One strip should fire up alone with a 24v driver.

 

[boyd crowder]

welp, im an idiot cause,its the terminal strip i was using
it was not a double side, it was a pass through so it was hard shorting my shit right on out....

 

[GBAUTO]

doh!!!
It's always the simple stuff
