Innovative open frame power supply for medical and industrial applications unveiled

Murata Manufacturing Co. Ltd has extended its line of open-frame AC to DC power supplies with the new PQC600. With its highly efficient and power-dense design, the device caters to the requirements of the latest medical and industrial applications, such as hospital beds, dentist chairs, medical equipment, and industrial process machinery.

Compactness, reliability, and efficiency is essential for contemporary power supplies. With its compact size and high-power density, this industrial-grade device is an excellent choice to fulfil these demands, offering 600W of power within a package less than 1U in height. Its dependable performance in medical and industrial settings is ensured through certification to the IEC 60601-1 Edition 3 medical safety standard, which includes 2 MOPP from primary to secondary, 1 MOPP from the chassis to ground and 1 MOPP from output to chassis. Also, the device complies with the IEC 60601-1-2 4th Edition for EMC standards, ensuring robust electromagnetic compatibility, and is suited to use with medical devices with Type B or Type BF applied parts.

The device uses Murata Power Solutions (MPS) bespoke transformer design and optimised layout and packaging design. With a 600W forced-air cooling design, it attains an impressive efficiency of 95% at full load. The power supply features an optimised interleaved PFC and back-end synchronous rectification, all within a compact, layered design that ensures superior thermal performance. Furthermore, the PQC600 includes a droop current-sharing feature, allowing multiple units to be configured in parallel for greater power scalability.

“Murata remains at the forefront of power supply innovation, creating denser and more efficient designs,” said Tony Sharp, director of product marketing at Murata Manufacturing Co Ltd. “The innovative new PQC600 will help to drive progress across both industrial and medical sectors, benefiting a new generation of equipment.”
