Power Entry Module: Advantages and How To Choose

A power entry module (PEM) is a part constructed to combine the functions of multiple relevant components into a single unit. As such, PEMs integrate the inlet of an appliance with other parts like its switch, EMI filter, fuse holder, and circuit breaker. They make setting up any electronic device easy by simplifying the power entry element and are often used in information technology and medical equipment. A PEM is worth the investment for a number of reasons that will be explored in the following article.

Electronics featuring detachable power entry cables require an inlet by which to connect a cable and supply the device with power. These inlets need to be connected to many parts to supply enough power to move the equipment and protect the user; this can cause the circuit to become messy. PEMs make the circuit less cluttered because they consist of one compact unit. Furthermore, they supply power to the respective device just like it would if it was constructed using individual components, but PEMs do so in a neater fashion that prevents complications.

A PEM allows for several components to be housed together, which saves space. This compact unit is also a safer option than alternatives because, to make repairs to the components in a PEM, the power cord assembly must be removed, reducing the risk of users being injured by an electric shock. Power entry modules are also capable of offering circuit protection in circuit breakers and fuses, meaning they are also easy to put together. Grouping many components which can be managed all at once, rather than handling each one separately, reduces both labor costs and time. Moreover, PEMs make it possible to avoid separately purchasing each individual component, saving the user time while making testing and data monitoring much simpler. Organizations that have limited storage space will benefit from PEMs because they take up little room.

It is important to select the correct PEM for your particular application, and there are several factors to consider when making the decision. First, there are AC and DC PEMs available; DC PEMs are typically used in telecommunication devices. Depending on the application, the power consumption of the PEM varies. Additionally, power entry modules help to save panel space and are available in a variety of sizes to suit your application. They are mounted either horizontally or vertically by using screws or soldering. Another consideration to make when considering a PEM is whether or not it features an integrated fuse which helps with its functionality. Any PEM you purchase should protect against EMI using filters that mitigate conductive EMI inside the circuit to combat radiated EMI.
