Mean Well DCW12A-05 DC-DC Converter - 12W - 9~18V in ±5V out 1.2A

The DCW12A-05 is a 12W DC-DC converter with a dual output of ±5V. It is designed for applications that need both positive and negative 5V rails from a 9 to 18V DC input range.

This model accepts 9 to 18V DC input, which is a 2:1 wide input range. That makes it suitable for systems where the input source can vary within that window but a regulated ±5V output is still required.

Yes. The converter has a compact metal case measuring 31.8 x 20.3 x 12.2 mm, which helps when board space is limited. Its five-sided shield metal case also supports use in compact industrial or embedded designs where durability matters.

The DCW12A-05 includes short circuit and overload protection. Its overload protection is rated at 110% to 180% with auto-recovery, and short circuit protection uses hiccup mode that recovers automatically after the fault is removed.

This model is rated for operation from -40°C to +71°C when used within its derating limits. It is also specified for storage from -40°C to +105°C, which makes it suitable for harsh equipment environments.

Yes. The converter provides 1500VDC input-to-output isolation, with isolation resistance specified at 100M Ohms under the stated test conditions. This is useful in applications where electrical isolation is required between the source side and the load side.
