Power entry module

Article summary

inlet connector and fuse holder. The fuse is protected by a sliding plastic cover, which requires the power lead to be removed before it can be opened. A power entry module (PEM) is an electromechanical component used in electrical appliances, integrating the appliance inlet with other components such as: * a switch, possibly including integrated or remote bowden cable actuation; * a circuit breaker, possibly including overload, overcurrent, or undercurrent protection, as well as remote triggering; * an appliance fuse holder; * a voltage selector; * an electromagnetic interference line filter; * an appliance outlet. Advantages of a power entry module over individual components: * compact dimensions; * unitized, standardized product with pre-assembled individual components; * efficient mounting; * alternative designs with similar dimensions may be substituted without major re-engineering; * protected, pre-wired, tested, and certified power components. Power entry modules are used to save labor in manufacturing electrical and electronic equipment powered by an external source, such as the AC powerline. They are also quite compact, taking up a small amount of space on the equipment’s chassis, or printed circuit board. Power entry modules frequently allow connections to the equipment circuitry using quick connect tab terminals, also known as blade connectors.…
