FAQ
Can I use the DKA30C-12 for a 12V industrial controller or HMI that needs a regulated output?
It is a regulated DC-DC converter with a dual ±12V output, up to 1.25A per rail and 30W rated power. The input range is 36-72VDC, so it fits applications that need ±12V regulation from a DC source within that input window.
Is the DKA30C-12 suitable for 12V embedded control boards inside factory equipment?
For embedded control loads that require steady 12V rails, this model provides a regulated ±12V dual output at up to 1.25A per rail and 30W. Its compact 50.8 × 50.8 × 21.0 mm size can also help in space-limited equipment housings.
Can this converter power 12V automation sensors or interface modules in a control cabinet?
It can be used where the connected modules need regulated ±12V power and the load stays within 1.25A per rail and 30W. The specified operating range of -40°C to +85°C (with output derating at high temperatures, see the derating curve) also suits demanding industrial temperature conditions.
Is the DKA30C-12 appropriate for outdoor or washdown environments?
The published specs list an operating temperature range of -40°C to +85°C, but they do not include an IP rating. That means the temperature capability is stated, while dust and water protection for outdoor or washdown exposure is not stated in the product data.
How does the DKA30C-12 compare with other DKA30C series options?
Within the listed siblings, the DKA30C-05 is rated at 25W with ±5V output and up to 2.5A per rail, while the DKA30C-15 is rated at 30W with ±15V output and up to 1A per rail. The DKA30C-12 sits between them at 30W, ±12V, and up to 1.25A per rail.
