Power Dissipation in Power Entry Modules

8 May 2024  

Power entry modules (PEMs) consist of a combination of different components for the safe power supply of devices. In addition to the IEC appliance inlet connector, mains switches, fuseholders or circuit breakers and filters can be integrated. The company claims all these components are tested according to their respective component standard so that the entire component can be certified by the certification bodies.

 Each of these components is designed for a specific minimum and maximum ambient temperature. Important: The maximum rated current may only be used at the rated temperature. At higher ambient temperatures, the current must be reduced accordingly. This is usually specified in the temperature derating on the data sheets.
