FAQ

Can I use the DKE10A-24 for industrial control equipment that needs ±24V rails?

It can fit low-power industrial control or signal-conditioning circuits that need a regulated ±24V output and stay within the unit's 10W rating. The input range is 9-18VDC, so it is suited to systems built around that source range rather than higher-voltage inputs.

Is the DKE10A-24 suitable for embedded instrumentation with bipolar analog stages?

Yes, it is a reasonable fit for embedded or measurement designs that use bipolar analog sections and need a regulated ±24V output. Its compact 50.8 × 25.4 × 11.2 mm size also helps where board or enclosure space is limited.

Can I use this converter in a small automation cabinet for isolated ±24V support power?

It can work in a compact automation assembly when the available source is 9-18VDC and the downstream load fits within 10W. The listed approvals include CE and FCC, which supports use in regulated equipment builds where those approvals matter.

Is the DKE10A-24 suitable for outdoor or harsh-environment use?

The provided specs list an operating temperature range of -25°C to +71°C, but they do not list any IP rating. Based on the stated data, it is better treated as a converter for protected indoor enclosures rather than exposed outdoor or washdown locations.

How does the DKE10A-24 compare with the other DKE10A models?

All DKE10A models are 10W converters in the same family, but they differ by output: DKE10A-05 is ±5V at up to ±1000mA, DKE10A-12 is ±12V at up to ±420mA, DKE10A-15 is ±15V at up to ±333mA, and DKE10A-24 is ±24V at up to ±210mA. This model is the ±24V version for applications that need the highest output voltage in the DKE10A series.
