Frequently Asked Questions

What is the Mean Well DCW12C-12 used for?

The DCW12C-12 is a 12W DC-DC converter for equipment that needs regulated power from a 36 to 72V DC source. It is suited to compact industrial and embedded applications where isolated ±12V output and a wide input range are important.

What are the key electrical specifications of the DCW12C-12?

This model accepts a 36 to 72V DC input and provides a ±12V output with a 12W power rating. It has voltage set point accuracy of ±2.0% max, line regulation of ±0.5% max, and load regulation of ±0.5% max at 10 to 100% load.

Does the DCW12C-12 provide input-to-output isolation?

Yes. The DCW12C-12 provides 1500VDC input-to-output isolation, with isolation resistance rated at 100M Ohms minimum at 500VDC. This makes it a fit for designs that require electrical isolation between the input source and output side.

How does the DCW12C-12 handle harsh operating environments?

The converter is rated for operation from -40 to +71°C, subject to the output derating curve. It also uses free air convection cooling and a five-sided shield metal case, which supports reliable use in compact industrial environments.

What protection features are included in the DCW12C-12?

The DCW12C-12 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.

What makes the DCW12C-12 a good choice compared with basic non-isolated DC-DC converters?

Compared with simpler non-isolated converters, this model adds 1500VDC isolation, a built-in EMI filter, and remote ON/OFF control. It also offers a 2:1 wide input range and EMC compliance to EN55022 Class B and FCC Part 15 Class B, which can be important in commercial and industrial designs.
