600W open frame AC-DC supply for scalable power

Murata has developed a compact 600W 1U open frame AC-DC power supply with power sharing for scalable power.

The PQC600 is aimed at medical and industrial process machinery and uses a bespoke transformer design from Murata Power Solutions (MPS) with an optimized layout and packaging design.

With forced-air cooling, the AC-DC power supply achieves efficiency of 95% at full load. Tit has an optimized interleaved Power Factor Correction (PFC) front end and back-end synchronous rectification, all within a compact, layered design that improves the thermal performance.

The PQC600 also includes a droop current sharing feature, enabling multiple units to be configured in parallel for greater power scalability.

The AC-DC power supply is certified to 2 MOPP isolation from primary to secondary and 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 innovative new PQC600 will help to drive progress across both industrial and medical sectors, benefiting a new generation of equipment,” said Tony Sharp, Director Product Marketing  at Murata Manufacturing.
