Interesting !!....How much current was it pulling under test when it exploded ?? They rate it to 3A max but I'm sure it's much less.....we just need to cover the surges for PAW. I haven't experienced any generated noise on the other avionics at all
I think it was running a 1A load, at the time I was tinkering with the input voltages and fast transients. It spiked the electronic load as it died as it shutoff with an over voltage alert at the same time. It did supply 3A, but as it got hot things started to get a bit iffy.
It depends on what you mean by noise on the other avionics. Audio interference is just part of the problem, and the one thing you can easily detect. What people don't detect is the loss of performance of equipment, normally seen a lower sensitivity owing to increased background noise on the signals. I had one where in the aircraft everything was great, when they transmitted the receiver heard poor quality audio. Another was poor GPS performance (poor signal strength, low sat count, slow lock etc.) and radio nav equipment not working at the normal ranges causing problems.
If you have it bolted to a metal sheet (also connected to ground) that will help prevent radiated interference, but it won't help conducted emissions. I'd also make sure it has, at most, a 2A fuse on it.
I wouldn't be surprised if some of the WiFi issues are simply down to swamping the receiver with noise, those WiFi dongles are pretty basic.
I have another one somewhere, as I bought two, it will be in a box somewhere in the office/lab. I have a TEM cell now for pre-compliance testing so if I find it and have the time I might run a few sweeps.
