In general, for patients who need long-term bedside care or chronical diseases, the burden on the family members or caregivers is very immense, so the market for assistive tools such as common electric beds, electrical wheelchairs, electric lifts, electrical prostheses, etc. are helpful for providing care to the patients. Such electrical assistive devices rely on DC voltage motors to drive or combine with battery control systems (BMS) for charging. Such applications can utilize MEAN WELL’s open frame PCB MPM/MFM/RPS power supply series for built-in power or GSM/GEM series for external charging adapters, all complying with 2xMOPP and suitable for BF type applications.
