Strips build confused...

Ok,
Ich allready have q diy set up,
There is something "wrong" or special..
I have 2 panel ( each 1,5foot × 3 foot)
Wired in parrallen/ konstant current(volt)
Each panel has 1 meanwell hlg240-24a

My Problem is, if i turn the volts and amps up(At tue driver with the little screwdriver)
My Power meter goes over 550watts
Is that normal, i thought i cant be more than 480watt (both panel togehter each max 240watt like the hlg240-24a says)

That is Problem no1.
(I dont have hope to Unterstand this anymore :( )


Now the next thing;

What is the safest and best way to wire These led strips
Parallel
Or
Series connected
?
And why to peple bis resistens with in the parallel?
I am soo confused

1 yeah thats normal. Its 2x240 at board level. Add to that that they tend to output just a bit more (think about 7%) and transofrmer efficiency of 93%$

2: those drivers will not power your strips in serial due to insufficient voltage. Cc drivers would be able to do seriial but tend to have a lot of voltage which is dangerous

1. I have to check the total Outputs, in full Power
(Inbuild Amps and volts turn of max/hlg240-24a)
I Think its more then 7% of 240w.
(I checked it , 1 driver goes from 20-290watt(+20%), and the other one from 80-270watt(+12%).
I just can adjust it with the voAdj.
The ioAdj "screw" does nothing, i can turn ut up and Down and nothing happends.)
Both the same hlg-240-24a one is Made in China and one Made in Taiwan.. )


2.sorry i mistaken , i mean i have a constant vintage driver not current.

So constant voltage is safer
Than constant current ?
I thought the higer amps at constant voltage are more dangerous.

And i often hear that people say parallel you have to jus resistence 3-5 Ohm for safty??? Didnt checked that

dpends a bit what you consdier as safer.
Thermal runaway, in series is safer.
high voltage, in parallel is safer.

This said, both work in most cases.
You need to touch + and - at once to get shocked by the meanwell dirver, not that easy normally.

Yeah, it seems most people don't understand that. It's isolated from ground.
I think when people are building or working on the light is the most dangerous since it's the the most likely time to touch both + and -.

And people worry about 300v rated connectors on LEDs..... 300v between what two points?
