FAQ

Can I use the SKA40C-15 for 15V automation or instrumentation electronics?

Yes, this converter provides constant 15V output and is rated for 40W with up to 2.67A output current. It is suitable for 15V automation, embedded, or instrumentation loads that stay within those limits.

Is the SKA40C-15 a fit for 15V control boards in systems with a 36-75VDC source?

It is built for a 36-75VDC input range and delivers a regulated 15V constant-voltage output. The output capacity is 40W total, with up to 2.67A available for the load.

Can this model power 15V sensing, measurement, or communications hardware?

It can power 15V electronics that require a constant-voltage supply, including sensing, measurement, or communications hardware within 40W. The maximum output current is 2.67A.

Would the SKA40C-15 work in a small embedded or control housing?

The unit measures 50.8 × 50.8 × 11.0 mm and weighs 50g, which supports compact integration. That can be useful in embedded or control assemblies where available space is limited.

Is the SKA40C-15 suitable for harsh temperature swings?

Its operating temperature range is specified as -40°C to +80°C. That makes it suitable for protected equipment exposed to wide ambient temperature changes.

Can this converter be used in exposed outdoor conditions?

The specs include the -40°C to +80°C operating range, but no IP rating is listed. Because ingress protection is not specified, the product data does not confirm use in exposed outdoor, wet, or dusty locations.

How does the SKA40C-15 differ from the other output options in the same series?

The SKA40C-05 is rated for 35W at 5V (7A), while the SKA40C-12 and SKA40C-15 are rated for 40W. The SKA40C-12 is 12V at 3.33A, and the SKA40C-15 is 15V at 2.67A.
