I'm replacing the dead 80W supply on my Full Spectrum with the JLD100W, and unlike the stock one, there there isn't a maximum current-limiting adjustment on this power supply, and there isn't mention of any in the documentation.

Is there an internal pot or similar I can use to dial down the maximum current, or am I limited to doing it all in software, as the FSLaser software/hardware already does as analog power control to the input line?

On the old power supply, this dial scaled the current output from 0 to (pot limit), whereas it looks like this model is 0 to software maximum. I was trying to lock down the absolute maximum current ever available to the tube as per the original PSU.

Sooo... no maximum power limit adjust on this model other than the PWM/Analog input line?

Thanks,
Dave

Dave:

The controller card is supposed to be able to limit the maximum output from a PSU. If you want to control the current, it is easy to do it. You can add a 3 legs variable resistor in between the controller card signal output pins and the PSU unit

See the diagram here.

Instead of connect +5V to the VR, you connect the output signal from the controller card
