Frequently Asked Questions

Can I use the SKA40A-05 to power a 5V embedded controller or single-board computer in equipment with a 9-18VAC input?

This converter provides a constant 5V output at up to 7A with 35W capacity. Its listed input range is 9-18VAC, so it suits embedded electronics that need 5V power from that source range.

Is the SKA40A-05 a fit for industrial USB hubs, gateways, or low-voltage IT hardware that need 5V power?

The output is regulated 5V with up to 7A available, which is useful for 5V IT or control hardware. The total output limit is 35W, so the load needs to remain within that rating.

Can this model support 5V automation electronics in vehicles or mobile equipment with a 9-18VAC supply range?

The listed input range is 9-18VAC and the output is a constant 5V. That makes it suitable where the source and the 5V load both match those published limits.

Would the SKA40A-05 work for compact control cabinets with limited space?

Its dimensions are 50.8 × 50.8 × 11.0 mm and its weight is 0.06 kg. Those specs support use in compact assemblies where a low-profile 5V, 35W converter is needed.

Can the SKA40A-05 be used in outdoor or temperature-variable environments?

The operating temperature range is specified as -40°C to +80°C. No IP rating is listed, so temperature capability is defined, but outdoor or washdown suitability is not established by the published specs.

What is the difference between the SKA40A-05 and the other SKA40A versions?

The SKA40A-05 is rated for 35W with 5V output at 7A. In the same series, the SKA40A-12 is 35W with 12V at 3.33A, and the SKA40A-15 is 35W with 15V at 2.67A.
