FAQ
Can I use the DKE15B-24 for industrial control electronics that need a ±24V rail?
Yes, this model is intended for applications that need a ±24V constant-voltage output and fit within a 15W power budget. It accepts 18-36VDC input, so it is best matched to industrial control or interface electronics operating in that input range.
Is the DKE15B-24 appropriate for automation or communications interface boards?
It can be used where an interface board requires a regulated ±24V output rather than a lower-voltage rail. The unit provides 15W total output power and is designed for systems with 18-36VDC input available.
Can this converter work in compact embedded or OEM equipment?
Yes, its 50.8 x 50.8 x 11.0 mm size and 60 g weight make it suitable for compact embedded or OEM assemblies. It is a better fit for low-power ±24V sections than for larger loads because the converter is rated at 15W.
Can the DKE15B-24 be used in unprotected outdoor enclosures?
The operating temperature range is -25°C to +71°C (with load derating per the derating curve), so the temperature spec is broad enough for many controlled environments. However, no IP rating is provided, so the listed specs do not support direct exposure to outdoor dust or water.
What is the difference between the DKE15B-24 and the other DKE15B versions?
All DKE15B models are 15W converters with 18-36VDC input, but they differ by output. The DKE15B-05 is ±5V at up to ±1500mA, the DKE15B-12 is ±12V at up to ±625mA, the DKE15B-15 is ±15V at up to ±500mA, and the DKE15B-24 is ±24V at up to ±313mA.
