600W open frame power supply for medical and industrial applications

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

With its compact size and high-power density, Murata’s industrial-grade PQC600 is suitable to fulfill these demands, offering 600W of power within a package that is less than 1U in height. Its dependable performance in medical and industrial settings is guaranteed through certification to the IEC 60601-1 Edition 3 medical safety standard, which includes 2 Means of Patient Protection (MOPP) from primary to secondary, 1 MOPP from the chassis to ground and 1 MOPP from output to chassis. Additionally, the PQC600 complies with the IEC 60601-1-2 4th Edition for EMC standards, ensuring robust electromagnetic compatibility, and is suitable for use with medical devices that have Type B or Type BF applied parts.

The PQC600 utilises Murata Power Solutions (MPS) bespoke transformer design and optimised layout and packaging design. With a 600W forced-air cooling design, it achieves an impressive efficiency of 95% at full load. The power supply features an optimised interleaved Power Factor Correction (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, enabling multiple units to be configured in parallel for greater power scalability.
