Hi All, We?ve got several things power by wall warts. But all with diffe rent voltages. 5V, 12V, 24V, 48V? and all get power from the standard 9m m power plug. (I think it?s 9mm?) I wondering if there is a simple way t o do over voltage protection so that if some one plugs a 12 V supply into a 5 V unit it doesn?t fry it. Yeah I?ll do a bit of internet searching too. (So for the 48V we just hard wire the power supply into the device.)
Thanks,
George H. (It?d be real nice if different voltage had different size plugs.)
