Mean Well DCW12C-05 DC-DC Converter - 12W - 36~72V in ±5V out 1.2A

The DCW12C-05 is a 12W DC-DC converter with a 36 to 72V DC input range and a regulated ±5V DC output. It is designed for applications that need dual 5V rails from a wide 2:1 input range. The rated output current is 1.2A.

This model is suited to industrial and OEM equipment that needs isolated DC-DC conversion from a 36 to 72V DC source. Its compact size, metal case, and built-in EMI filter make it a practical choice for embedded power designs where space and noise control matter. Buyers often consider it for systems requiring dual ±5V output in a modular converter format.

Yes. The DCW12C-05 provides 1500VDC input-to-output isolation. It also specifies input-to-output isolation resistance of 100M Ohms at 500VDC under stated test conditions.

The converter includes overload protection with auto-recovery, specified at 110% to 180%. It also has short circuit protection on all outputs using hiccup-mode recovery after the fault condition is removed. These protections help support reliability in demanding equipment designs.

It is rated for operation from -40°C to +71°C, subject to the output derating curve. Storage temperature is specified from -40°C to +105°C. That makes it appropriate for a wide range of industrial environments where temperature tolerance is important.

Compared with non-isolated converters, the DCW12C-05 adds 1500VDC isolation between input and output, which can be important for noise control and system protection. It also includes a built-in EMI filter and a five-sided shield metal case. Those features make it better suited to applications where isolation and EMC performance are priorities.

The DCW12C-05 measures 31.8 x 20.3 x 12.2mm and uses a five-sided shield metal case. Mean Well specifies 100% full-load burn-in testing for this model. It also carries a 2-year warranty.
