Multi-Output Power Supply for Handheld Medical Robotics System
The medical technology company required a highly specialized and customized power assembly that was capable of accommodating a broad input AC range, spanning from 90VAC to 264VAC. This wide range was essential to ensure compatibility with various power sources and to maintain consistent performance across different environments. The assembly needed to function efficiently at frequencies between 48Hz and 62Hz, adhering to Class I Earth Ground specifications to ensure safety and reliability. The company specified the need for output voltages that included a robust primary power supply, referred to as Power Supply #1, which was tasked with delivering a steady 48VDC at a power output ranging from 550 to 600 watts. This was crucial for powering the main components of the handheld robotics system. Additionally, a secondary power supply, known as Power Supply #2, was required to provide 12VDC at a power output between 300 and 400 watts, along with a 5V standby power (5Vsb) to support auxiliary functions and ensure the system's readiness for operation. Furthermore, the company placed significant emphasis on the necessity for GPIO (General Purpose Input/Output) support, which included features such as AC OK, DC OK, and Remote On/Off capabilities. These features were vital for monitoring the power status and enabling remote control of the system, thereby enhancing operational efficiency and safety. The power assembly also had to comply with stringent safety standards, including IEC60601-1, which pertains to the safety of medical electrical equipment, 2MOPP (Means of Patient Protection), BF (Body Floating), and IEC60601-1-2 Class B, which addresses electromagnetic compatibility requirements. These standards were critical to ensure the safety and effectiveness of the medical robotics system in clinical settings.
