Just a quick question for all the electronic brainiacs out there who know a lot about power supplies.
I'm currently using a Leadshine SPS705 (68vdc) unregulated power supply which seems to be on it's last legs. Output voltage is fluctuating really badly, going from zero to 50ishV and back down, often failing to even reach 50vdc and slumping down to barely 20ish vdc. No idea what failed or why it failed, it is only used 2-3 times a day and only for 10-15sec, then off all the time, has a single stepper motor on it with a DM856 controller.
Plan of action is to check all the diodes in the bridge and possibly try to repair or get a new unit, but it will take around 20min to get the current unit out of the machine so I wanted to double check what it might be before trying to fix.
Rgds,
