Power Entry Modules (PEMs), crucial for the safe power supply of devices, integrate various components such as IEC appliance inlet connectors, mains switches, fuseholders or circuit breakers, and filters. Areas where Schurter offers a complete portfolio of solutions, where each component undergoes rigorous testing according to respective standards, enabling certification by regulatory bodies.
Power entry modules consist of a combination of components for the safe power supply of devices. In addition to the IEC appliance inlet connector and mains switches, where the fuseholders or circuit breakers and filters can be integrated, each of these components is designed for a specific minimum and maximum ambient temperature. As the new white paper highlights, 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.
As power entry modules are installed in a cut-out in the appliance housing, the different ambient temperatures inside and outside must be taken into account. Inside, higher temperatures are almost always to be expected during operation, as the electrical load leads to heating (e.g. switching power supply, power semiconductors and heating elements).
The new Schurter White Paper highlights the importance of considering ambient temperatures inside and outside the appliance, particularly concerning components such as fuses, fuseholders, and circuit breakers. Through meticulous testing and measurement methodologies, Schurter ensures that temperature deratings are correctly applied, guaranteeing the long-lasting and secure operation of PEMs.
