FAQ
What are the main electrical ratings of the Mean Well DCW08B-05?
The DCW08B-05 is an 8W DC-DC converter with an 18 to 36V DC input range and a ±5V DC output. It is rated for 800mA output current and has a typical efficiency of 78%.
What kinds of applications is the DCW08B-05 suited for?
This model is suited for industrial and OEM applications that need compact 8W DC-DC conversion from a 24V-class DC input range. Its isolated design, built-in EMI filter, and shielded metal case make it a practical fit for embedded power systems and control equipment.
Can the DCW08B-05 be used in demanding temperature conditions?
Yes, the DCW08B-05 is rated for operation from -40°C to +71°C when used within its derating limits. Its storage temperature range is broader, from -40°C to +105°C, which supports use in harsh storage and transport environments.
What protection features does the DCW08B-05 include?
The unit includes short circuit protection and overload protection, both in hiccup mode with automatic recovery. Overload protection is specified at 110% to 250% of rated output load, helping protect the converter during abnormal load conditions.
How compact is the Mean Well DCW08B-05?
The DCW08B-05 measures 31.8 x 20.3 x 12.2mm, making it a very compact board-level power module. It also weighs about 17.5g and uses a five-sided shield metal case for a small but durable form factor.
What compliance and reliability details are listed for this model?
The DCW08B-05 is listed as compliant with EN55032 Class B, FCC Part 15 Class B, and several EN61000-4 immunity standards. It is also described as having 100% full load burn-in testing and comes with a 2-year warranty.
