FAQ
Can I use the DKA15C-15 for 15V analog or control sections in industrial systems?
Yes. This converter provides constant-voltage 15V output from a 36-72VAC 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 constant 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 36-72VAC and the auxiliary rail needs constant 15V output. The 15W power rating 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, 36-72VAC input, 50.8 × 25.4 × 11.27 mm dimensions, -40°C to +71°C operating range, and a 2-year warranty. The outputs are different: DKA15C-05 is 5V at 1.5A, DKA15C-12 is 12V at 625A, and DKA15C-15 is 15V at 500A.
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.
