Learn more about the four new additions to CUI Inc's high-density AC-DC power supply series for medical applications.

CUI Inc today announced the addition of four high-density ac-dc power supply series to its medical product family. The VMS-450BVMS-450B-CFVMS-450B-CFS, and VMS-450B-CNF offer 450 W of continuous power from compact chassis mount packages. These ac-dc supplies have been designed for space-constrained medical and dental applications where reliability and regulatory compliance are major concerns.



The VMS-450B, VMS-450B-CF, VMS-450B-CFS, and VMS-450B-CNF comply with the medical 60601-1 edition 3.1 safety standards for 2 x MOPP applications and 4th edition EMC requirements. These internal medical power supplies additionally offer 5 Vdc AUX output, power factor correction, and over temperature, over voltage, over current, and short circuit protections.

With an industry standard 3" x 5" footprint and an open frame package, the VMS-450B is ideal for applications with less space and heat management outside of the unit. The VMS-450B-CF, VMS-450B-CFS, and VMS-450B-CNF come in a metal case with various fan configurations for ultimate flexibility;

  • VMS-450B-CF - Top Fan

  • VMS-450B-CNF - No Fan
  • VMS-450B - Open Frame
