The top section shows a fully assembled module, highlighting key features: a circuit protection drawer located at the top for housing fuses, a voltage selector positioned just below the drawer for switching between voltage settings, a power switch for turning the module on and off, a filter for reducing electrical interference, and a power inlet at the base (with an option for a power outlet). The lower section provides an exploded view of the module, breaking down its internal components. This includes an AC power inlet as the primary entry point for electrical current, an RFI/EMI filter to minimize radio frequency and electromagnetic interference, an RF metal shield for shielding sensitive components, a fuse holder integrated into the circuit protection drawer, and the voltage selector mechanism for adjusting between 115V and 230V. The accompanying caption explains that this is just one example of a module, noting the availability of various styles and functional combinations to suit different applications.](https://blog.interpower.com/hubfs/Interpower_November2017/images/InfoPower%20Blog/customer-question-and-answer-700x367.jpg)](https://blog.interpower.com/infopower/top-interpower-customer-service-questions-of-2024) Hospital-grade Filtered Module Issue?
