Frequently Asked Questions

Can I use the SKMW20G-05 for 5V industrial computers, gateways, or controller electronics from a high-voltage bus?

Yes, if the equipment needs constant 5V output and draws no more than 4A. This model accepts an 18-75V input range and is rated for 20W.

Is the SKMW20G-05 appropriate for 5V embedded systems in telecom or industrial control equipment?

It is suitable where a regulated 5V rail is needed from an 18-75V source. The converter provides constant-voltage output at 5V with up to 4A available.

Can this converter be used when I need 5V power in a very small module footprint?

Yes, the dimensions are 25.4 × 25.4 × 10.2 mm and the weight is 0.018 kg. Within that size, it delivers up to 20W at 5V.

Is the SKMW20G-05 suitable for harsh environments or outdoor cabinets?

The operating temperature range is -40°C to +85°C, which supports use across wide ambient conditions. The provided specifications do not include an IP rating, so outdoor sealing performance is not stated.

What is the difference between the SKMW20G-05 and the other SKMW20G versions?

The SKMW20G series uses the same 20W platform with different output ratings. The sibling models are 3.3V at 4.5A, 12V at 1.67A, and 15V at 1.33A, while this model is 5V at 4A.
