FAQ

Can I use the SKA40A-15 to run a 15V automation controller or industrial interface module?

This model provides a constant 15V output with up to 2.67A available and a 40W maximum rating. It suits 15V automation or interface loads that operate within those limits and use a 9-18VDC input.

Is the SKA40A-15 appropriate for 15V embedded systems that need regulated power from a 9-18VDC source?

The listed input range is 9-18VDC, and the output is a fixed 15V. That makes it suitable for embedded systems that need a stable 15V rail and draw no more than 2.67A.

Can this converter power 15V test, monitoring, or communications equipment in compact industrial enclosures?

The converter is rated for 40W at 15V constant voltage output. With dimensions of 50.8 × 50.8 × 11.0 mm and a weight of 50g, it can fit compact equipment where a low-profile 15V supply is needed.

Would the SKA40A-15 work in equipment exposed to wide ambient temperatures?

Its operating temperature range is specified as -40°C to +80°C. That supports use in equipment that sees cold-start or elevated-temperature conditions within that range.

Can the SKA40A-15 be used in outdoor or exposed environments?

The published specs define temperature capability at -40°C to +80°C, but they do not list an IP rating. Based on the provided information, environmental sealing for outdoor exposure is not specified.

What are the key differences between the SKA40A-15 and the other SKA40A models?

The SKA40A-15 is rated at 40W with 15V output and 2.67A output current. The SKA40A-05 provides 35W at 5V and 7A, while the SKA40A-12 provides 40W at 12V and 3.33A.
