I'm calling according to the image below. What could be wrong? It is normal to be giving source followed snaps?

Hi, I'm trying to connect the LEDs with drivers mean well ldd-1000, but when I turn the power supply is giving several clicks when I turn on the LEDs in the direct source without going through the drivers she works normal.

Hi!
The wiring seems good.
This "click" is a noise or flash.
Until 1 minute after turn on the controller is normal some oscillation in the light.
Best regards.

Fernando, that click is a noise coming from inside the unit.
the font is this

I'm using 10 LEDs of 3W and 700mA in series

Hi!
This power supply is bivolt?
Is regulated to how many volts?
Each LED needs of how many volts?
Best regards.

Hi Fernando, the source is multi-voltage, use the output 36v, 3.2a. Each LED is 3V, 700mA.
thanks.
thanks.

So the output should be: 10 x 3 V (for LEDs) + 3 V (for LDD) = 33 V.

Yes, but make sure that this LED is 3 V because 3 V x 0.7 A = 2.1 Watt or the max. current is 1A.

Now I have a question, because when I turn the LEDs on direct source without going through the usual ldd drivers it works without making any hiss?

Maybe because the power supply is sending all voltage without any restriction.
You will burn your LEDs of this way.
EDIT: BTW for 700 mA use the LDD-700H.

Hello, I'm here Meanwell drivers ldd-1000h but the LEDs are 700mA, if I call these LEDs with this driver, they will burn. Is there any way to catch the maximum output current to 700mA of these drivers?
Thank you.
Thank you.

Hi!
Yes, you will burn the LEDs.
I can't see a good reason to connect resistor or other circuit between LDD and LEDs.
Buy a new LDD or use only a MOSFET to control the voltage. The circuit is available on forum.
Best regards.

Hi, if you use MOSFET, the operation is the same as LDD?

Hi!
No, because there no direct control over the current.
The control is over the voltage.
Best regards.

Okay, so how do I replace the LDD for MOSFET? Or you do not like?
tank you

I think better use a LDD but, there many people using MOSFET.
Here an example: viewtopic.php?f=25&t=53
