APPLICATION
The PMM20 Series from Powerbox (Cosel) offers 20W of regulated, isolated output power across wide 2:1 and 4:1 input voltage ranges (9-18V, 18-36V, 36-75V, and 9-36V dc). With single and dual outputs from 3.3V to ±15V, it achieves efficiencies up to 91%. Designed for medical and patient-connected systems, the PMM20 Series provides 2 MOPP isolation, low leakage current (<2µA), and comprehensive protection including over-current, over-voltage, and short-circuit. Certified to IEC60601-1 3rd Edition, EN60601-1, and UL62368-1.
