What are the key medical compliance features of QM AC-DC power supplies?

Posted by Dulcie on November 30, 2018

Designed as a medical power supply, the QM has an earth leakage of less than 300µA and touch current of <100µA.

Even with such low earth leakage, the QM series achieves Class B conducted and radiated EMC emissions performance to EN55011/55022. It also meets all the immunity requirements for medical products in EN60601-1-2 Edition 4 and the generic immunity requirement for EN61000-6-2. The entire series is also approved to the 2nd and 3rd Editions of EN60601-1, including ANSI/AAMI ES 60601-1 and CSA – C22/2 60601-1-08.

Full MoPP isolation, make the QM power module suitable for more medical applications, including B and BF-type equipment and simplifies system design.
