FAQ

Can I use the SKA20C-15 to power a 15V industrial sensor or transmitter from a wide input bus?

This model provides a constant-voltage 15V output at up to 1.33A with 20W capacity. Its listed input range is 36-75VDC, so it fits applications that need 15V output within that input window.

Is the SKA20C-15 suitable for embedded control boards that need regulated 15V power?

It is designed as a constant-voltage converter with 15V output and 20W maximum power. That makes it appropriate for embedded or control assemblies that require a fixed 15V rail and draw no more than 1.33A.

Can this converter be used in automation equipment that runs in hot or cold environments?

The specified operating temperature range is -40°C to +85°C. That wide range supports use in automation or industrial equipment exposed to low and high ambient temperatures within those limits.

Can the SKA20C-15 power a small 15V communications or IT device from a 36-75VDC source?

Yes, the listed specs match a 36-75VDC input range and a regulated 15V output. The output is limited to 20W and 1.33A, so the connected device needs to stay within that capacity.

Is the SKA20C-15 suitable for outdoor or exposed-environment use?

The provided specs include an operating temperature range of -40°C to +85°C, but no IP rating is listed. Based on the listed data alone, temperature capability is defined, while outdoor or exposed-use protection is not confirmed.

How does the SKA20C-15 compare with other SKA20C models?

Within the SKA20C series, the SKA20C-15 is rated for 20W with 15V output at 1.33A. The sibling SKA20C-05 is 20W with 5V output at 4A, and the SKA20C-12 is 20W with 12V output at 1.66A.
