[QUOTE="Vipersan, post: 914013, member: 325666"] DAMMIT !! The 24v 8amp 200W switch mode just died .. No fireworks ...and only the AZ gbox active at the time ... Nothing running hot to the touch ?? I simply reversed direction on the positioner...which had been running flawlessly for hours ... The psu had been in use for at least a week... But it died...and didn't even pop the 4amp fuse in the motor line... Shyte components maybe ? Maybe a brief moment when the relays weren't synced ...a delay in contacts opening/closing... who knows ... I guess I never will .. But ..this psu is supposed to have short circuit protection..? Very frustrating indeed ...and of course I cant return it cos I modified it to fit.. To say the least I'm gutted and now contemplating returning to a torroidal transformer generated 24v supply ...which _should_ cope better with loading and switching direction with relays.. If I do I'll still use a 12v switch mode for all but the motor power.. Grrrrr [/QUOTE]
