FAQ

Can I use the SKA20C-12 for a 12V industrial controller or automation module on a 36-75VDC input?

Yes, this converter accepts 36-75VDC input and delivers a constant 12V output. It is suitable for 12V loads up to 1.66A, within the 20W output rating.

Is the SKA20C-12 appropriate for 12V monitoring, control, or embedded hardware in higher-input systems?

It can be used when the application needs regulated 12V power from a 36-75VDC source. The connected equipment needs to stay within 1.66A output current and 20W maximum power.

Can this model support 12V industrial interface electronics where the source voltage varies across 36-75VDC?

That is the intended input window for this model, and the output is fixed at 12V in constant-voltage mode. It fits 12V interface or control electronics that do not exceed 1.66A.

What temperature and exposure conditions are specified for the SKA20C-12?

The published operating temperature range is -40°C to +85°C. The specs do not include an IP rating, so the product information does not state indoor sealed use, outdoor use, or weather resistance.

How does the SKA20C-12 compare with SKA20C-05 and SKA20C-15?

These SKA20C models all use the same 36-75VAC input range, 20W power class, 50.8 × 25.4 × 11.2 mm dimensions, 0.0312 kg weight, and -40°C to +85°C operating range. The output choices are 5V at 4A for SKA20C-05, 12V at 1.66A for SKA20C-12, and 15V at 1.33A for SKA20C-15.
