Most controllers at the Ruida level have both pwm and analog outputs. Some of these are wired to the analog, some to the pwm… As far as I know there is no difference.
I don’t think we’ve asked enough people about this or if they are technical enough to understand the question.
This is a good idea, but this isn’t what appears to be causing this issue. Wouldn’t hurt someone to try it …
The Ruida produces the PWM continuously while running a layer and enables it to lase via the L input. So the problem is visible as the L input stays high and it lases… that’s what @ednisley scope trace shows. It may not matter, but there are a whole lot of Ruida controllers around and we don’t see this with every lps.
No matter how you look at it, the specification say, it will lase when L goes low at the IN current control voltage.
It is lasing when the L terminal is high… there is no other option but the device is bad or it would follow the control input.
Make sense?
