Konstant Labs' PWRchekrs so you can easily keep an eye on your DC rails' health. The most sensible 1 hp module ever!

IMy main issue isn't dust etc. unfortunately. I live on the California coast and salt air corrosion is a problem with electronic connections and tool corrosion, I use a lot of contact cleaner, so this might be perfect.
I just ordered 4 PWR Checkers to put in this new rack (1 HP is a perfect size) to give 'em a try.
Thanks,
