APPLICATION
The Cosel PMM20 Series is a 20W medical-grade DC-DC converter designed for compact, high-performance applications. It features 5000VAC isolation, 2MOPP compliance, and 8mm clearance and creepage for medical safety. With wide 2:1 and 4:1 input ranges and single or dual output configurations, it ensures reliable power delivery across demanding conditions, including operation at altitudes up to 5000m.
The converter delivers precise voltage regulation with ±1% accuracy and low ripple, while integrated protections for overvoltage, overload, and short circuits ensure stability. Operating from -40°C to +105°C with derating, it complies with IEC/EN/ANSI/AAMI ES60601-1 standards and meets stringent EMI/EMC requirements for Class A and Class B. The PMM20 Series is ideal for medical, industrial, instrumentation, and laboratory environments requiring safe and efficient power conversion in a compact PCB-mounted solution.
