I've got a funny little issue I can't figure out on my Powerstation.
It's set up to run 3x 24v lines, with C1 and C2 removed. When testing outside of it's case, it's working perfectly with no issues whatsoever.
This is just the capacitors around the regs charging from the meter that makes the value go up and up. That is fine and normal. As long as there is no dead short between the regs metal tab and chassis.However, in it's case, it's blowing fuses instantly on start up. I initially thought it was the voltage regs making contact, but I don't believe this is true. I'm able to easily measure resistance between the LM317's and the case (all close values aswell), and prior to blowing the fuse the last time, I could measure resistance between the LM337's and the case, however after blowing the fuse I now get a resistance that is constantly ticking up (starting at around 200ohms and working up- it doesn't seem to want to stop). I'm guessing this isn't normal?
If the fuse blows and nothing on the powerstation is smoking then something is wired wrong and making a dead short.All resistors seem to be checking out fine, and as mentioned, it's working great when not in the case. Any ideas?
When you say out of case is working I presume with no load attached to the powerstation dc outputs?
When you are testing in the case and the fuse is blowing is this still with nothing attached to the DC outputs on the powerstation?
Need to see me some photo's of your wiring and mounting in the case to see what is going on. Send them to my email so I can check them over. Large in focus macro on photo's are best.
