2015-1-4u2002·u2002To OP, if you are referring to say the typical SMPS supplies, they are usually marked Gnd, L and N and can be switched from 120v/230v. The L and N should be observed if possible, although the supply functions fine in either connection, there is usually a glass fuse fitted internally in the L conductor.
Get PriceThere are three terminal lugs on the supply labeled 'L' for 'live' (usually called 'hot' in the US), 'N' for 'neutral,' and 'G' for 'ground.' With a standard US power cord, the ribbed insulator is used for neutral and the smooth insulator is used for live/hot; the wider prong is neutral and the smaller prong is live/hot, applicable to both 2-prong ungrounded (NEMA 1-15) and 3-prong grounded ...

The power supply has a number of screw terminals, labeled AC (N), AC (L), FG, three GND terminals, and two +24V for the recoil board (s). So I have the recoil power harness connected to one of the +24V and one of the GND terminals.

Get PriceSolenoids are commonly used in experimental research requiring magnetic fields. A solenoid is generally easy to wind, and near its center, its magnetic field is quite uniform and directly proportional to the current in the wire. (Figure) shows a solenoid consisting of N turns of wire tightly wound over a length L.
