Can you tell about power cartridge?

A power cartridge is a modular component that supplies electrical power to a device or system. It typically contains a power supply unit (PSU) that converts mains voltage to the required DC voltage levels, along with protection features such as over‑current, over‑voltage, and short‑circuit protection. Power cartridges are common in devices like printers, scanners, and industrial equipment where the power supply needs to be easily replaceable or upgradeable. For example, a printer’s power cartridge might provide 12 V and 5 V rails for the motor and control board, and it can be swapped out without opening the printer’s enclosure. The cartridge may also include a fuse or circuit breaker to protect the device from power surges. In summary, a power cartridge is a plug‑and‑play power module that simplifies maintenance and ensures reliable power delivery to the device it serves.
