FAQ
What is the Mean Well DCW08A-12 designed for?
The DCW08A-12 is an 8W DC-DC converter intended for applications that need isolated DC power conversion from a 9 to 18V DC input. It is suited to compact OEM and industrial designs where a regulated ±12V output and built-in EMI filtering are important.
What input range and output does the DCW08A-12 provide?
This model accepts a 9 to 18V DC input, which is a 2:1 wide input range. It provides a ±12V output and is rated for 8W total power, with a listed rated current of 335mA.
Does the DCW08A-12 provide isolation between input and output?
Yes. The product features input-to-output isolation, with the feature list stating 1500VDC isolation and the specification listing a 1.5KVDC I/P-O/P withstand voltage. It also specifies up to 250pF isolation capacitance and at least 100MΩ isolation resistance at 500VDC.
What protection features are included in the DCW08A-12?
The DCW08A-12 includes short circuit and overload protection. Both work in hiccup mode with auto-recovery, and overload protection is specified at 110% to 250% of rated output load.
Can the DCW08A-12 be used in demanding temperature conditions?
This converter is rated for operation from -40 to +71°C, subject to the output derating curve. Its storage temperature range is -40 to +105°C, which supports use in a wide range of industrial environments.
What are the size, construction, and reliability highlights of the DCW08A-12?
The DCW08A-12 has compact dimensions of 31.8 x 20.3 x 12.2mm and uses a five-sided shield metal case. It is cooled by free air convection, includes a built-in EMI filter, and undergoes 100% full-load burn-in testing. Mean Well also lists a 2-year warranty for this model.
