FAQ
Can I use the DKE15A-24 for low-power industrial control electronics that need ±24V rails?
Yes, this model provides a ±24V constant-voltage output from a 9-18VDC input. Its 15W rating makes it appropriate for low-power industrial control or interface electronics rather than heavier loads.
Is the DKE15A-24 suitable for automation signal-conditioning modules with ±24V requirements?
It can be a fit for low-power automation or signal-conditioning modules that require ±24V and remain within the 15W limit. The converter is intended for systems with a 9-18VDC input source.
Would this converter work in embedded monitoring equipment that needs split ±24V power?
Yes, it can be used in embedded monitoring or specialty electronics that require a ±24V output and modest power demand. The compact 50.8 × 50.8 × 11.0 mm size is also useful where space is tight.
Can the DKE15A-24 be used in low-power instrumentation assemblies?
It is suitable for low-power instrumentation assemblies that need a constant ±24V output and can operate from 9-18VDC input. The 15W power ceiling is the key sizing limit for the application.
Is the DKE15A-24 rated for harsh or exposed environments?
The published operating temperature is -25°C to +71°C (with load derating per the derating curve), so temperature performance is defined within that range. No IP rating is listed, so exposed outdoor or wet-location suitability is not established by the provided data.
How is the DKE15A-24 different from the other DKE15A output options?
The DKE15A series shares the same 15W rating and 9-18VDC input range, while the output options vary. The sibling models are DKE15A-05 at ±5V and up to ±1500mA, DKE15A-12 at ±12V and up to ±625mA, DKE15A-15 at ±15V and up to ±500mA, and DKE15A-24 at ±24V and up to ±313mA.
