FAQ

Can I use the DKE15B-05 in industrial electronics that need ±5V from an 18-36VDC source?

Yes, this converter is designed for a 18-36VDC input and a ±5V constant-voltage output. With a 15W rating, it fits low-power industrial electronics, logic support, and interface functions rather than larger loads.

Is the DKE15B-05 suitable for embedded control or processor boards that need split ±5V rails?

It can be used for embedded control or processor-support boards that require ±5V and stay within the 15W output limit. The 50.8 × 50.8 × 11.0 mm size also helps in compact assemblies.

Would this model work for low-power automation interfaces running on a higher input range?

Yes, the 18-36VDC input range makes it relevant where the source is above the 9-18VDC class and the load needs ±5V. It is best matched to low-power automation and interface electronics within the 15W rating.

Can the DKE15B-05 be used in IT or communications equipment with low-power ±5V sections?

It can be suitable for low-power IT or communications electronics that require a ±5V constant-voltage output and have an 18-36VDC input available. The key limits are the 15W output rating and the defined input range.

Is the DKE15B-05 appropriate for outdoor cabinets or exposed locations?

The specifications give an operating temperature range of -25°C to +71°C (with load derating per the derating curve), but they do not provide an IP rating. That means temperature capability is stated, while exposed outdoor protection is not defined in the listed specs.

How does the DKE15B-05 compare with the other DKE15B versions?

The DKE15B family keeps the same 15W power rating and 18-36VDC input range across the series. The listed outputs are DKE15B-05 at ±5V and up to ±1500mA, DKE15B-12 at ±12V and up to ±625mA, DKE15B-15 at ±15V and up to ±500mA, and DKE15B-24 at ±24V and up to ±313mA.
