Powered beds can be adjusted to improve a person's comfort when lying flat or with one's head or feet raised. While primarily found in hospitals, adjustable beds are now used at home for patients expected to be bedridden for extended periods of time.
The key element in a powered bed is the motion control for moving parts that need to be quiet and efficient. We have a large offer of power MOSFETs, monolithic motor drivers and STM32 microcontrollers as well as a comprehensive set of hardware and software evaluation and development tools to help design efficient motor control solutions.
