PSU not driving laser to rated power
Posted: Thu Nov 09, 2017 11:26 pm
Hey Guys,
Just getting my laser up and running... finally... been a year and a half project...
I am using the LO-x7 DSP and a laser power supply and 40w tube from coletech on ebay.
when driving the laser at 98% I am only getting 9.4 milliamps on my amp meter.
when cutting 1/8 ply, I have to run it at 7mm/sec to cut through. I was reading an article that said you should be able to cut 1/8 ply at around 14mm/sec. this indicates to me that my amp meter is probably true and I am only getting about half power out of my laser.
I checked the PWM output from the controller and it is putting out 4.88 volts at 98% power. this seems about right.
My question is, could it be that I was sold a 220v power supply and not a 110v supply. the ebay listing did state 110v input but there is no markings on the PS that indicates voltage. is there an easy way to tell what the voltage of the PS should be? I will attach some pics of my PS and voltage inputs. anybody have similar experiences?
Thanks for the help!
