FAQ

Can I use the DKE15A-15 for industrial analog or measurement circuits that need ±15V rails?

Yes, this converter is designed for a 9-18VDC input and a ±15V constant-voltage output. Its 15W capacity makes it suitable for low-power analog, measurement, and conditioning circuits rather than larger loads.

Is the DKE15A-15 a good fit for embedded test equipment with split ±15V power requirements?

It can be used in embedded test or monitoring equipment that requires ±15V and stays within the 15W rating. The 50.8 × 50.8 × 11.0 mm form factor also suits compact equipment layouts.

Can this model support low-power automation electronics that run from a 9-18VDC source?

Yes, if the automation electronics need a ±15V constant-voltage output and the total demand fits within 15W. That makes it a practical option for smaller control and interface sections fed from 9-18VDC.

Would the DKE15A-15 work for legacy control boards that expect ±15V power?

It is suited to low-power legacy or retrofit control electronics that require ±15V rails and can accept the 15W output limit. Input availability also needs to match the 9-18VDC range listed for this model.

Can the DKE15A-15 be used in outdoor enclosures?

The listed operating temperature is -25°C to +71°C (with load derating per the derating curve), which defines the temperature window for operation. However, no IP rating is provided, so exposed outdoor suitability is not confirmed by the stated specs.

What are the output differences across the DKE15A series?

The DKE15A family keeps the same 15W power rating and 9-18VDC input range across the group. The listed siblings 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.
