Hello,

I just purchased this power supply from you, LSR-JN150W-1V 100W~180W PWM CO2 Laser Power Supply (AC110V)

and it doesn't seem to have a potentiometer, how am I supposed to adjust the current?

Hello:

In general, if you have DSP controller card install, you don't control power by the potentiometer but through PWM. If you need run it on other controller like TB6560 through Mach3 or other non digital controller, then you need to add a 5K or 10K VR

You may download the power supply connection from the "Download" area. By using the VR, you can manually control the output. By default, there is no VR built in on any LPSU

I've looked through the download area and can't seem to find the correct documents. Could you please provided a link?

Not a problem
