Mean Well LDDHW
I’m hoping someone who has looked at the LDD output voltage with an oscilloscope can chime in whether there is any significant LF voltage ripple. If there isn’t anything significant, I’m not sure ldx-1000hw much worry there is about syncing or flickering on the output side Options Quote message in reply?
What is a cookie? I don’t know enough about electronics to know the reasons, but parallelling the LDDs apparently maxes out at about 1.

Just to clarify, you’re talking about recovery time from conductance to non-conductance in a standard p-n junction diode potentially causing an issue using PWM? Originally Posted by galleon.
The dim pin is referenced to the common terminal of the LDD, so as long as you don’t touch the LED output pins or the Voltage input you wont hurt anything BB code is On. An oscilloscope would be able to determine this.

The low side diodes would be redundant and not needed. Originally Posted by galleon I’m interested in why you think meanwel.
Aside from oscilloscope to monitor LF ripple characteristics on the output once the drivers were wired in parallel, would it be enough to watch the amperage on a multimeter to make sure the current didn’t start fluctuating to values higher than the max emitter spec?
