FAQ

Can I use the DKE15C-24 in a 36-72V industrial control system that needs ±24V output?

Yes, this converter is built for a 36-72VDC input range and provides a ±24V dual constant-voltage output. It is a fit for low-power industrial control loads where the total demand stays within 15W.

Is the DKE15C-24 suitable for powering ±24V automation modules from a higher-voltage bus?

It can be used where the DC source falls within 36-72VDC and the downstream device needs a regulated ±24V output. The key sizing limit is the 15W power rating, so it is intended for lighter-duty automation electronics rather than larger loads.

Can this converter be used in embedded or industrial electronics that standardize on ±24V rails?

Yes, the ±24V dual constant-voltage output makes it appropriate for embedded or industrial electronics designed around ±24V rails. Its compact 50.8 × 50.8 × 11.0 mm size also suits space-constrained equipment where the load remains within 15W.

What is the difference between the DKE15C-24 and the other DKE15C models?

All listed DKE15C models are 15W converters, but they differ by output. The DKE15C-05 is ±5V at up to ±1500mA, the DKE15C-12 is ±12V at up to ±625mA, the DKE15C-15 is ±15V at up to ±500mA, and this DKE15C-24 is ±24V at up to ±313mA.

Is the DKE15C-24 appropriate for outdoor or harsh-environment use?

The published operating temperature is -25°C to +71°C (with load derating per the derating curve), so that is the supported temperature window. No IP rating is listed in the provided specs, so exposed outdoor or washdown use is not supported by the stated environmental data.
