Power Module Stable Power Supply for Communication Equipment

A power entry module serves as the gateway to an external power source used to supply electronic equipment, and interfaces it with its internal components. Functions such as connecting power, filtering, and even protection are handled by it. Power entry modules usually have features such as electromagnetic interference (EMI) filtering to stop external electrical noise from getting into the equipment and disrupting it. In addition, Power entry modules have protective mechanisms such as over-current and over-voltage to protect components from power-supply changes. In communication devices, a well-designed power entry module guarantees stable and clean power, essential for sensitive communication elements to operate.
