Mean Well MDD03G-12 Medical Grade DC/DC Converter 3W - 18-75V input, 12 and -12V output

This model is suited to low-power 12V instrumentation or sensor circuits that need constant-voltage output and stay within 0.12A. With 3W total output power, it is a fit for light control and monitoring loads rather than higher-draw 12V devices.

It can fit embedded control designs that need a regulated 12V rail and operate from the listed 18-75V input range. The converter provides 12V at 0.12A, so the connected 12V section must remain within that output limit.

Yes, it is positioned for medical-grade applications and carries CB, CCC, CE, EAC, ENEC, and UL certifications, which can be relevant in medical or lab equipment designs. Electrically, it is intended for low-power 12V sections up to 0.12A with 3W available output power.

The MDD03G-12 outputs 12V at 0.12A, while the MDD03G-05 outputs 5V at 0.3A and the MDD03G-15 outputs 15V at 0.1A. All three are 3W models with the same 18-75V input range, -40°C to +90°C operating temperature range, 31.8 × 20.3 × 12.2 mm size, and 0.017 kg weight.

Its stated operating range is -40°C to +90°C, which supports broad temperature conditions inside suitable equipment. However, no IP rating is provided, so the specs do not establish outdoor, weather-exposed, or unsealed enclosure suitability.
