FAQ

What are the key electrical specs of the Mean Well DCW08A-15?

The DCW08A-15 is an 8W DC-DC converter with a 9 to 18V DC input range and dual ±15V DC output. It is rated for 267mA output current and has a typical efficiency of 80%. Voltage set point accuracy is specified at ±2% maximum.

Is the DCW08A-15 an isolated DC-DC converter?

Yes, this model is an isolated DC-DC converter designed with input-to-output isolation. The product features call out 1500VDC I/O isolation, and the specification lists an I/P-O/P withstand voltage of 1.5KVDC. It also uses a five-sided shield metal case and built-in EMI filter for improved electrical performance.

What kinds of applications is the DCW08A-15 suited for?

This converter is suited for low-power DC-DC applications that need dual ±15V outputs from a 9 to 18V DC source. Its compact size, isolated design, and built-in EMI filtering make it relevant for embedded electronics, industrial assemblies, and other space-constrained OEM designs. Buyers looking for a modular 8W converter with wide 2:1 input range often consider this type of unit.

How does the DCW08A-15 handle overload and short circuit conditions?

The DCW08A-15 includes both overload and short circuit protection with auto-recovery behavior. Overload protection is specified at 110% to 250% of rated output load, and both protections work in hiccup mode. The unit recovers automatically after the fault condition is removed, though it should not be left in overload or short circuit for more than 30 seconds.

What operating temperature range is supported by the DCW08A-15?

This model is rated for operation from -40°C to +71°C, with reference to the output derating curve. Storage temperature is specified from -40°C to +105°C. Cooling is by free air convection, with no fan required.

How compact is the Mean Well DCW08A-15?

The DCW08A-15 measures 31.8 x 20.3 x 12.2 mm, which is approximately 1.25 x 0.80 x 0.48 inches. Its listed weight is 17.5g. That small modular form factor makes it useful where board or enclosure space is limited.
