Mean Well DCW12B-15 DC-DC Converter - 12W - 18~36V in ±15V out 400mA

The DCW12B-15 is a 12W DC-DC converter with a 2:1 input range of 18 to 36V DC. It provides dual ±15V DC output, making it suitable for designs that need positive and negative supply rails from a nominal 24V DC source.

Yes. This model provides 1500V DC input-to-output isolation, with isolation resistance rated at 100M Ohms at 500V DC. That isolation can be useful in control, instrumentation, and other applications where signal separation is important.

The DCW12B-15 includes short circuit and overload protection. Overload protection is specified at 110% to 180% with auto-recovery, and short circuit protection uses hiccup mode that recovers automatically after the fault is removed.

It is designed with a built-in EMI filter and a five-sided shield metal case. The unit also lists EMC compliance to EN55022 Class B, EN61000-4-2/3/4/5/6/8, and FCC Part 15 Class B, which supports use in space-constrained industrial and commercial equipment.

This converter is rated for operation from -40°C to +71°C, subject to the output derating curve. Its storage temperature range is -40°C to +105°C, which makes it suitable for demanding operating and transport conditions.

The DCW12B-15 measures 31.8 x 20.3 x 12.2 mm and weighs about 0.0185 kg. That compact metal-cased format makes it a practical choice where board space and enclosure space are limited.
