Test conditions and notes5

1.All parameters are specified at normal input(E:5Vdc, A:12Vdc, B:24Vdc, C:48Vdc), rated load, 25℃ 70% RH ambient.
2.Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1μf & 47μf 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.The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”(as available on http://www.meanwell.com)

FAQ

Can I use the DKM10B-12 in a 24V industrial control cabinet that needs 12V DC rails?

Yes. The DKM10B-12 accepts 18-36VDC input and provides a constant voltage ±12V output with 10W power. That makes it suitable for industrial control and automation equipment that operates within that input range and needs a compact 25.4 × 25.4 × 10.2 mm converter.

Is this converter a good fit for embedded systems that need isolated 12V power from a wide input range?

It can fit embedded and board-level designs that require constant voltage ±12V output and have an available 18-36VDC source. Its 10W rating and 18.3g weight support use in compact assemblies where space and mass matter. The EAC TP TC 020/2011 safety standard approval can also be relevant in regulated equipment builds.

Can the DKM10B-12 be used for analog or signal-conditioning sections in automation equipment?

It is intended for applications that need a steady ±12V constant voltage supply from 18-36VDC input. In automation or embedded equipment, that can make it appropriate for analog support circuits, interface sections, or auxiliary power rails that stay within the 10W limit. The compact package helps in dense control hardware.

Is the DKM10B-12 suitable for outdoor or high-temperature environments?

The specified operating temperature is -40°C to +85°C, so it is designed for a wide temperature range. No IP rating is provided, so this product should not be treated as an outdoor or washdown-rated unit based on the listed specs alone. It is better evaluated as a component for protected enclosures.

How does the DKM10B-12 compare with the other DKM10B models?

Within the DKM10B series, the DKM10B-05 is 10W with ±5V output and ±1000mA, the DKM10B-12 is 10W with ±12V output and ±416mA, and the DKM10B-15 is 10W with ±15V output and ±333mA. All are part of the same 10W family. The main difference is the output voltage and listed output current.
