I was wondering if anyone here had any recommendations for power supplies that would be good at protecting connected mircocontrollers in environments where there are lots of p.i.d. heaters and servos on the same AC lines.
my boards are inside of metal boxes (mounted under a machine) with a bunch of p.l.c. and networking stuff around it.
Some machines provide 120vac and others are 230vac, so an input range close to that is desirable.
Good lightning/spike suppression/protection integrated into the P.S. would be an excellent feature!
Yesterday i had a synchronization issue with an ethernet shield and one of my switchmode power supplies where if the AC adapter were plugged into the wall while the arduino was connected (or like powering up the machine!), the DC voltage came up too slowly and the W5100 ethernet controller would just blink on and then off for a second meaning i had to manually push the reset (which kinda sucks when the panel's bolted shut..).
So a power supply that doesnt output until it's (internally) up to voltage or a fast ramp would be really nice!
i am also interested in filters for my existing units as an alternative (in case the price of decent to exceptional grade power supplies is too much).
thank you everyone very much for any suggestions in advance!!! :)
