Test conditions and notes5

1.All parameters are specified at normal input, rated load, 25℃ 70% RH ambient.
2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1uf & 47uf capacitor.
3.Line regulation is measured from low line to high line at rated load.
4.Load regulation is measured from 10% to 100% rated load.
5.Please prevent the converter from operating in overload or short circuit condition for more than 30 seconds.

FAQ

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

Yes. It provides a regulated dual ±5V output from a 9-18VDC input and is rated at 25W with up to 2.5A per rail. 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 9-18VDC input and need regulated ±5V rails. With 25W capacity and up to 2.5A per rail, 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 9-18VDC and the auxiliary section needs a regulated ±5V output. The converter is rated for 25W and up to 2.5A per rail, 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 9-18VDC 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 up to 2.5A per rail, DKA30A-12 is 30W with ±12V at up to 1.25A per rail, and DKA30A-15 is 30W with ±15V at up to 1A per rail.

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

The specified operating range is -40°C to +85°C, with output derating at high temperatures per the derating curve. No IP rating is listed, so the provided specs do not identify it for outdoor or washdown exposure.
