FAQ
What does the Mean Well DCW08B-12 do?
The DCW08B-12 is an 8W DC-DC converter designed to take an 18 to 36V DC input and provide a ±12V DC output. It is intended for applications that need compact, regulated DC conversion in a modular form factor.
What input and output ratings does this model have?
This model accepts a 2:1 input range of 18 to 36V DC. Its output is ±12V DC, with a rated current of 335 mA, and the unit is rated for 8W total output power.
What protection features are included on the DCW08B-12?
The product includes short circuit protection and overload protection with auto-recovery in hiccup mode. The overload protection is listed at 110% to 250% of rated output load, helping protect the converter during abnormal load conditions.
Is the DCW08B-12 suitable for demanding industrial environments?
It is built for a wide operating temperature range of -40 to +71°C, with derating referenced at higher temperatures. The unit also includes a built-in EMI filter, a shielded metal case, and EMC compliance listed for EN55032 Class B, FCC Part 15 Class B, and several EN61000-4 immunity standards.
How compact is this DC-DC converter?
The DCW08B-12 has a compact metal case measuring 31.8 x 20.3 x 12.2 mm. Its listed weight is 17.5g, making it suitable for space-constrained equipment designs.
What kinds of applications is this model best suited for?
This model is a fit for equipment that needs regulated low-power DC conversion from a nominal 24V-class input range to ±12V output rails. Typical buyer interest would include embedded electronics, control systems, and other compact industrial or OEM power applications where isolation, small size, and convection cooling are useful.
