Power Source Guide 2016
AC/DC power supplies: Components/devices that convert an AC input to one or more DC outputs. Products are distinguished by their different output voltages and wattages and by use and form factor.
Batteries: Electrochemical cells that can be charged electrically to provide a static potential for power or released electrical charge when needed.
Capacitors: Passive electronic components consisting of a pair of conductors separated by a dielectric.
Circuit protection devices: Devices that are used to stop current flow or open the circuit, including circuit breakers, fuses, and surge suppressors.
Cooling devices: Devices involving the absorption of heat when current is sent through a junction of two dissimilar metals.
