FAQ

What is the main use case for the Mean Well SCW05B-05 DC-DC converter?

The SCW05B-05 is a 5W DC-DC converter designed for applications that need a regulated 5V DC output from an 18 to 36V DC input source. It is suited to embedded, industrial, and OEM equipment where compact size, isolation, and reliable DC voltage conversion are important.

What input and output ratings does the SCW05B-05 provide?

This model accepts 18 to 36V DC input and provides a 5V DC output. Its power rating is 5W, and the rated output current is 1.0A.

Is the SCW05B-05 an isolated DC-DC converter?

Yes. The product description lists 1000VDC input-to-output isolation for this series, with a 3000VDC isolation option also noted. That makes it a practical choice where electrical isolation between input and output is required.

What protection and reliability features are included in the SCW05B-05?

The SCW05B-05 includes short circuit and overload protection with auto-recovery behavior noted in the description. It also features a built-in EMI filter, a five-sided shield metal case, and 100% burn-in testing to support dependable operation.

What operating temperature range is supported by the SCW05B-05?

This model is specified for operation from -40°C to 71°C, with output load derating at higher temperatures per the datasheet derating curve. That range makes it suitable for use in demanding environments where electronics may be exposed to both low and elevated ambient temperatures.

How accurate is the output regulation on the SCW05B-05?

The listed voltage accuracy is ±2%. Line regulation is specified at ±0.5%, and load regulation is ±0.5% measured from 20% to 100% rated load.

What warranty comes with the Mean Well SCW05B-05?

The SCW05B-05 includes a 2-year warranty. This aligns with the product's positioning as a low-cost, high-reliability modular DC-DC converter.
