Info on Spellman PCM series high voltage power supply
I'm looking for information on how to enable the variable current limit on this power supply. The one I have is fixed even with the built-in pot wired up as in the manual at the Spellman Web site: http://www.spellmanhv.com/tech/pdf/PCMMAN.pdf There should be a way to make it variable, probably adding or moving a resistor but the circuit board markings are no help. Any info appreciated. I've beent to the Spellman Web site and sent them a request for assitance twice with no reply. Thanks. --- sam | Sci.Electronics.Repair FAQ: http://www.repairfaq.org/ Repair | Main Table of Contents: http://www.repairfaq.org/REPAIR/ +Lasers | Sam's Laser FAQ: http://www.repairfaq.org/sam/lasersam.htm | Mirror Sites: http://www.repairfaq.org/REPAIR/F_mirror.html Important: Anything sent to the email address in the message header above is ignored unless my full name is included in the subject line.
