Mean Well DCW12A-15 DC-DC Converter - 12W - 9~18V in ±15V out 400mA

The DCW12A-15 is a 12W DC-DC converter with a 9 to 18V DC input range. It provides a ±15V output and is designed for applications that need regulated bipolar DC output from a nominal 12V input source.

This model is rated at 400 mA and 12W total output power. For buyers comparing compact isolated converters, that makes it suitable for lower-power bipolar supply requirements rather than higher-current load demands.

Yes. The DCW12A-15 includes 1500VDC input-to-output isolation, which helps separate the input side from the output side in sensitive electronic systems. It also specifies up to 100M Ohms isolation resistance at 500VDC under the stated test conditions.

This model includes short circuit and overload protection. The short circuit protection uses hiccup-mode recovery, and overload protection is specified at 110% to 180% with automatic recovery after the fault is cleared.

The DCW12A-15 is specified for operation from -40°C to +71°C, subject to the output derating curve. Its storage temperature range is -40°C to +105°C, making it suitable for demanding industrial and embedded environments where wider temperature tolerance is required.

This converter is compact at 31.8 x 20.3 x 12.2 mm and uses a five-sided shield metal case. It also uses free air convection cooling and has a built-in EMI filter, which makes it a practical option for compact OEM and control-system designs where size, shielding, and reliability matter.
