Up until now, my understanding of electricity and safety has been pretty ba= sic. Batteries around the house, 9v etc, the development boards, I've been= playing with, and so on, I don't worry it can hurt me. If it is househol= d 220 v AC, then I treat it with respect. Even if I do know the light swi= tch is off, I still test it with a multimeter to be double sure. But I don't know what comes out of this power supply. It goes up to 30 vol= ts and 1 Ampere. So as an example, just touching wires on motors like I wo= uld with a battery, can this thing be set high enough that I could get a (b= ad) shock? Thanks!
