FAQ

Can I use the DKA15C-05 to power 5V logic or controller boards from a 36-72VDC system?

Yes. This model provides a regulated ±5V dual output from a 36-72VDC input and is rated at 15W with up to 1500mA per output. That makes it a fit for low-power 5V control electronics where the source falls within the listed input range.

Is the DKA15C-05 suitable for embedded 5V electronics inside industrial equipment?

It is designed for a regulated ±5V output and has a compact 50.8 × 25.4 × 11.27 mm package, which suits space-constrained embedded designs. Its 15W rating and 1500mA maximum current per output make it appropriate for lower-power 5V electronics rather than higher-load systems.

Can this converter be used for 5V auxiliary power in automation panels with a wide source range?

Yes, if the available source is within 36-72VDC and the load needs a regulated ±5V output. The unit is rated for 15W and up to 1500mA per output, so it is best matched to auxiliary 5V panel electronics within that power envelope.

What is the difference between DKA15C-05, DKA15C-12, and DKA15C-15?

All 3 models share the same 15W rating, 36-72VDC input range, 50.8 × 25.4 × 11.27 mm dimensions, -40°C to +71°C operating range (with derating), and 2-year warranty. The difference is output: DKA15C-05 is ±5V at up to 1500mA, DKA15C-12 is ±12V at up to 625mA, and DKA15C-15 is ±15V at up to 500mA.

Is the DKA15C-05 suitable for outdoor or harsh-temperature use?

The operating temperature range is -40°C to +71°C, with output derating at higher temperatures per the derating curve, so it is specified for a wide temperature span. No IP rating is listed in the provided specs, so the product data does not identify it as an outdoor-rated converter.
