Frequently Asked Questions

Can I use the DKA30A-05 to power 5V industrial controllers from a 9-18VAC source?

Yes. It provides constant-voltage 5V output from a 9-18VAC input and is rated at 25W with 2.5A output current. That makes it suitable for low-power 5V controller or logic loads within that source range.

Is the DKA30A-05 suitable for embedded 5V electronics in vehicles or battery-based equipment?

It can fit applications that provide 9-18VAC input and need a constant 5V output rail. With 25W capacity and 2.5A output current, it is intended for modest 5V embedded loads rather than larger 5V power systems.

Can this model be used for 5V auxiliary power in automation cabinets with low-voltage input?

Yes, if the cabinet source is within 9-18VAC and the auxiliary section needs constant 5V output. The converter is rated for 25W and 2.5A, which defines the load level it can support.

What is the difference between DKA30A-05, DKA30A-12, and DKA30A-15?

These models share the same 9-18VAC input range, 50.8 × 50.8 × 21.0 mm dimensions, -40°C to +85°C operating range, and 2-year warranty. The outputs differ: DKA30A-05 is 25W with 5V at 2.5A, DKA30A-12 is 30W with 12V at 1.25A, and DKA30A-15 is 30W with 15V at 1A.

Can the DKA30A-05 be used in hot or cold environments?

The specified operating range is -40°C to +85°C, which covers both low and high ambient temperatures. No IP rating is listed, so the provided specs do not identify it for outdoor or washdown exposure.
