Power Management Modules (PMM) are electronic systems that control and monitor the power usage of a given device. They manage and control the power supply from the power grid to the device, control the power supply and adapt it to the current needs of the device, and protect the device from any sudden drops or surges in power or temperature. They can be used to regulate power and temperature in a wide variety of applications including computers, robotics, audio equipment, medical machines, and more. They are compact and efficient, meaning they take up less space and require less energy to run than traditional systems. And, they can be upgraded or reprogrammed to fit the needs of whatever application they are used for. PMMs are an important part of improving energy efficiency, performance, and device longevity.
