I have troubles with a JDS Uniphase Power Supply 2111-65MLQYV.
It turns on only from time to time. The start signal comes from an electronic board to the 25pin D-Sub connector. Unfortunately I haven't any information about the pinout of the 25pin D-Sub on the power supply. So I'm not able to identify on witch side the failure is happen.
Is there some body how have information about this power supply?
Don't apologise for your English, it's far better than many native English speakers' that I've read! The connections you need to make are: Pin 1 to pin 3 (interlock) Pin 13 to pin 2 (laser on) Current control signal to pin 6; put a 1K potentiometer between pin 11 (0V) and pin 13 (15V internal supply) with the wiper to pin 6 OR use an external
0 to 15V supply to pin 6 grounded to pin 11. Light control signal to pin 7; put a 1K potentiometer between pin 11 (0V) and pin 13 (15V internal supply) with the wiper to pin 7 OR use an external
0 to 15V supply to pin 7 grounded to pin 11. To select current control mode, put a link between pin 22 and 5; leave the link out for power (light) control mode. Pins 10,11,14,20,21,22 & 24 are all connected to 0V Pin 8 is the power monitor pin, the scaling depends on the exact version of laser head you have connected. Pin 9 is the current monitor pin, scaling is 0.1V / Amp. Hope that helps. By the way, you may want to visit the alt.lasers group as you may find lots of useful information on there. Martin
But if it doesn't start all the time, could be something else wrong.
