FAQ

Can I use the DKA15C-15 for 15V analog or control sections in industrial systems?

Yes. This converter provides a regulated ±15V dual output from a 36-72VDC input and is rated at 15W. It is suited to lower-power 15V sections that need a regulated output within that input range.

Is the DKA15C-15 suitable for embedded 15V electronics where board space is limited?

It is compact at 50.8 × 25.4 × 11.27 mm, which helps in dense embedded layouts. With regulated ±15V output and a 15W rating, it is intended for smaller 15V electronics rather than higher-power loads.

Can this converter serve as a 15V auxiliary rail in automation equipment?

Yes, when the source is within 36-72VDC and the auxiliary rail needs regulated 15V output. The 15W power rating (up to 500mA per output) sets the load size it is designed to support.

What are the differences between DKA15C-15 and the 5V or 12V versions?

All 3 DKA15C models share 15W power, 36-72VDC input, 50.8 × 25.4 × 11.27 mm dimensions, -40°C to +71°C operating range (with derating), and a 2-year warranty. The outputs are different: 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-15 appropriate for outdoor installations?

The listed operating temperature range is -40°C to +71°C, so the unit is specified for wide temperature conditions. However, no IP rating is given, so the product specs do not identify it as outdoor-rated.
