FAQ

What are the key input and output specs of the Mean Well DCW12C-15?

The Mean Well DCW12C-15 is a 12W DC-DC converter with a 36 to 72V DC input range and a ±15V DC output. It is rated for 400mA output current and is designed for applications that need regulated dual-output DC power from a wide input range.

What kind of isolation does the DCW12C-15 provide?

This model provides 1500VDC input-to-output isolation. It also specifies input-to-output isolation resistance of 100M Ohms at 500VDC and a maximum isolation capacitance of 2200pF.

Is the DCW12C-15 suitable for harsh temperature environments?

The DCW12C-15 has a working temperature range of -40 to +71 degrees C, subject to the output derating curve. Its storage temperature range is -40 to +105 degrees C, which makes it suitable for demanding industrial environments.

What protection features are included in the Mean Well DCW12C-15?

The DCW12C-15 includes overload protection rated at 110% to 180% with automatic recovery. It also has short circuit protection on all outputs using hiccup-mode overcurrent protection, which recovers automatically after the fault is removed.

What types of applications is the DCW12C-15 commonly used for?

This converter is suited to industrial and OEM applications that need compact isolated DC-DC power conversion from a 36 to 72V DC source to a regulated ±15V output. Its wide 2:1 input range, shielded metal case, built-in EMI filter, and remote ON/OFF capability make it a practical option for embedded power designs.

How compact is the Mean Well DCW12C-15?

The DCW12C-15 measures 31.8 x 20.3 x 12.2 mm and weighs about 17.5 g. Its compact size and five-sided shield metal case help it fit space-constrained industrial and embedded applications.
