Mean Well DCW12A-12 DC-DC Converter - 12W - 9~18V in ±12V out 500mA

The DCW12A-12 is a 12W isolated DC-DC converter for applications that need a 9 to 18V DC input and a ±12V DC output. It is suited to compact industrial and embedded systems where regulated dual-output DC power and input-to-output isolation are required.

This model is rated for 12W output power, with a 9 to 18V DC input range and ±12V output. The rated output current is 500 mA, and voltage set point accuracy is specified at ±2.0% maximum.

Yes, the DCW12A-12 provides 1500VDC input-to-output isolation. Its general specification lists I/P-O/P isolation voltage at 1.5KVDC, along with isolation resistance of 100M Ohms at 500VDC.

This converter 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 for a wide operating temperature range of -40 to +71°C, subject to the output derating curve. Storage temperature is specified from -40 to +105°C, which supports use in harsher industrial environments than many general-purpose converters.

The DCW12A-12 has compact dimensions of 31.8 x 20.3 x 12.2 mm and weighs 0.0185 kg. It also uses a five-sided shield metal case, which helps combine small size with mechanical protection and EMI shielding.

The unit includes a built-in EMI filter, 100% full load burn-in testing, and a two-year warranty. EMC compliance is listed to EN55022 Class B, EN61000-4-2,3,4,5,6,8, and FCC Part 15 Class B.
