The PM400 series of AC/DC power supplies from Protek Power, Hudson, MA, provides 400W of performance as well as compliance to UL 60601-1 and TUV 60601-1 medical safety standards. The low profile, 4 x 7 x 1.58-in. footprint is good for a many medical and dental applications, including patient vicinity medical devices. 

The series show efficiencies greater than 88%, leakage currents as low as 300µA at 264Vac, and 4000Vac input-output isolation voltage for the PM400 Series. Comprehensive protection circuitry, including overvoltage and short circuit protection, is inherent in the design. EMC performance meets Level B standards and units have an MTBF of 350,000 hours at full load.
