AC Power Entry Modules are components that are used to manage incoming AC power, protecting equipment, and manage the power. They feature power switches, filters, surge protectors, fuses, and transformers, along with other inputs for power cables and output connectors for electronic equipment. Components in the Modules are designed to minimize risk of electric shock and component fire due to moisture, excessive temperatures, and other environmental forces. In addition, they can protect sensitive data from power spikes and surges that can be damaging to electronic equipment. In order for them to be effective, they must be kept in all environments that use electrical systems.
