A high performance AC to DC external power supply family designed for medical applications. The ME20A Medical Series
low power external AC-DC power supplies are approved to safety EN/IEC/UL60601-1, 3rd edition with isolation levels
*
which satisfy the 2 MOPP requirements and designed to UL/EN/IEC60601-1-2, 4th edition for EMC . The ME20A Series
models will operate at universal input range of 90 to 264Vac over the wide temperature range of -20°C to +50°C,
delivering full rated output power up to +40°C and applicable output power derating at 50°C. These models are available
in desktop and wall-plug versions; include an IP22 rating per IEC60529 for the enclosure, and output cable terminated at
a variety of output connectors. These models use only high quality electrolytic capacitors, providing greater than 10
years life operating at rated output conditions.

1. Measured at the output connector, with noise probe directly across output and load terminated with 0.1μF ceramic and 10μF low ESR capacitors. For 5V and
6V models, values listed are typical, 100mV pk-pk maximum with 0.1μF ceramic and 47μF low ESR capacitors used at measurement point.
2. Order blade kit KT-1027K for other blades (EU. UK, Australia)
3. For EU fixed blades, replace “C” in the model number with “M”, for UK blades, replace “C” with “G”, for Australia blades, replace “C” with “H”.
4. For Input Class I models: For AC GND connected to output common (-), insert a “B” in the part number where the “A” is located (ME20B0503F01).
5. All specifications are typical at nominal input, full load, at 25°C ambient unless noted.
