PMM03

The COSEL PMM03 Series is a compact 3.3W medical DC-DC converter designed for high reliability in medical and industrial applications. It features reinforced insulation for 250VAC working voltage, 5000VAC input-to-output isolation, and a low patient leakage current of 2μA, ensuring compliance with ANSI/AAMI ES60601-1, EN60601-1, and related standards. With single and dual output options, it supports 2:1 and 4:1 input voltage ranges, covering 4.5–75VDC, and provides precise voltage regulation with built-in protections for overvoltage, overload, and short circuits.

Operating in ambient temperatures from -40°C to +105°C, the PMM03 Series is robust, meeting MIL-STD-810F for shock and vibration. Its non-conductive plastic case, flame-retardant potting, and built-in EMI Class A filter enhance durability and noise immunity. Suitable for medical devices and industrial systems, this converter combines high efficiency, compact design, and compliance with stringent safety and environmental standards.
