Bear Power to Design Custom 300 Watt Medical Power Supply



Bear Power Supplies has won a contract to design a custom 300 Watt medical power supply for a US-based medical equipment manufacturer. The custom AC/DC converter will have a universal input and multiple outputs to power the entire system, including a 175 VDC output to drive a solenoid, a 4 mA current output to power a sensor, and outputs to drive displays and indicators.

Bear won the contract to design the power supply as part of the customer’s system redesign and upgrade. In the process, the Bear engineering team identified several opportunities to improve the overall system by incorporating additional features into the power supply. For example, the power supply will incorporate a microcontroller (MCU) to replace a number of analog circuits in the system, simplify the control, reduce component count, and make the system more configurable.

Bear will do the circuit design and PCB layout for the open-frame custom medical power supply. It will be certified to IEC 60601 standards and be integrated into the customer’s equipment for use in clinical settings.
