FAQ

Can I use the DKE15A-05 for 5V embedded or controller electronics in a 9-18V system?

Yes, this model is intended for a ±5V dual constant-voltage output from a 9-18VDC input range. With a 15W rating, it fits low-power embedded, controller, or automation electronics that need ±5V rather than ±12V, ±15V, or ±24V.

Is the DKE15A-05 suitable for powering 5V industrial sensors or logic circuits?

It can be used for ±5V constant-voltage loads that stay within the 15W power limit. The output current range of up to ±1500mA per output also points it toward smaller control and logic-side applications instead of higher-power 5V equipment.

Can this converter be used inside compact automation equipment with limited space?

It is still a relatively compact unit at 50.8 × 50.8 × 11.0 mm, which can work inside many control or embedded assemblies. The key application fit is ±5V constant-voltage output, 9-18VDC input, and a 15W power ceiling.

How does the DKE15A-05 compare with the other DKE15A models?

The DKE15A family shares 15W power, constant-voltage operation, 9-18VDC input, 50.8 × 50.8 × 11.0 mm dimensions, 60 g weight, and -25°C to +71°C operation with derating. The output options are ±5V at up to ±1500mA for DKE15A-05, ±12V at up to ±625mA for DKE15A-12, ±15V at up to ±500mA for DKE15A-15, and ±24V at up to ±313mA for DKE15A-24.

Is the DKE15A-05 suitable for outdoor environments or wide temperature swings?

The operating temperature range is listed as -25°C to +71°C (with load derating per the derating curve), so temperature performance is defined within that band. No IP rating is provided, so outdoor or exposed-environment suitability cannot be confirmed from the specs shown.
