SCHURTER: Power Dissipation in Power Entry Modules
If different electrical components are combined in an appliance inlet to form a power entry module, the individual power losses and temperature deratings of all components involved must be carefully taken into account in order to ensure long-term safe operation. 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.
