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 DKA30B-05 to power 5V logic in industrial control equipment?

Yes, this model fits industrial control electronics that need regulated 5V rails. It provides a dual ±5V output at up to 2.5A per rail with a 25W rating and accepts 18-36VDC input.

Is the DKA30B-05 suitable for embedded controllers or interface boards running on 5V?

It is suitable for embedded controllers or interface boards designed for a regulated 5V supply. The converter delivers a regulated ±5V output at up to 2.5A per rail, so it is aimed at lower-power embedded and automation electronics rather than loads above 25W.

Can this converter be used for IT or communications electronics that need 5V from an 18-36VDC source?

Yes, if the IT or communications device is specified for a regulated 5V supply and the available source is within 18-36VDC. The 25W power limit and up to 2.5A per rail of the ±5V output define the usable load range.

Will the DKA30B-05 work in wide-temperature industrial environments?

The operating temperature range is -40°C to +85°C (with output derating at high temperatures, see the derating curve), which supports use in equipment that sees large temperature swings. No IP rating is listed in the provided specs, so the product data does not confirm outdoor exposure or ingress protection by itself.

What is the difference between the DKA30B-05, DKA30B-12, and DKA30B-15?

The DKA30B-05 is rated for 25W with ±5V output at up to 2.5A per rail, the DKA30B-12 is rated for 30W with ±12V output at up to 1.25A per rail, and the DKA30B-15 is rated for 30W with ±15V output at up to 1A per rail. They are all dual-output models in the DKA30B series and share the same 18-36VDC input range.
