Laser PSU voltage divider 1000:1 ratio. i.e. 20KV should read ~20V on the meter display.
I do not recommend that anybody do this. Very dangerous. but if someone were to try this then make sure you have the correct components and lay all of this onto an insulated wood board. and make sure you wire everything up and are able to get a good distance away before energizing and taking the reading.
I got this divider built and when I went to use it I decided against it as I was not able to do it safely without removing the PSU from my machine.
I’m an engineer at XP Power and we deal with high voltage testing all the time. This type of test should not be performed by the end user in reality.
and again to CMA I will say that no body should try this.
LMAO about the 1 Giga-Ohm resistor, they even make Terra-Ohm resistors lol. and who though MegaOhms were the highest ??
Is there a way to make something like this that has a built in meter that we could install in-line into the machine & have the meter in our control panel? That might be a safer way for people to keep track of their laser PSU high voltage line. I’m not hugely knowledgeable regarding electronics, but just had a thought that something permanent to monitor the PSU voltages would be nice for diagnostic purposes.
@Yuusuf_Sallahuddin_Y it’s possible yes. But would need to be well insulated and protected and really should only be done by a qualified tech. But hey we are all DIY maker types right
It’s not the same, of course.
