I’ve been using 3 x DPS-750RB in series connected to a boost converter charging at 74v 11Amps. I’ve managed to fry the DC grounded PSU (well it doesn’t power on anymore). This has happened twice now.
I only noticed the PSU didn’t power on when I went to charge the next day. So now sure if I did anything.
Q1. I’m wondering if I accidentally turned off the AC, before disconnecting the battery? Not sure if this can cause a reverse current that could fry the PSU?
Q2. Are there any issues with 3 PSUs in series?
Q3. Any common components that blow in the DPS-750rb’s?
Any pointers greatly appreciated!
