Test conditions and notes5

1.All parameters are specified at normal input(L:5Vdc, M:12Vdc, N:24Vdc), 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 20% 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 DPU01L-12 for low-power analog or sensor interface stages that need a 12V rail?

Yes, this model is suited to low-power circuits because it is rated at 1W with ±12V constant-voltage output. Its listed output current is ±42mA, so it fits light-load interface and signal electronics rather than higher-power devices.

Is the DPU01L-12 appropriate for compact industrial or embedded control boards?

It is a practical fit where board space is tight, since the package is 19.5 × 6.1 × 10.2 mm and weighs 2.3g. The converter is also intended for low-power use at 1W.

Can the DPU01L-12 be used in electronics exposed to extreme temperatures?

Yes, the specified operating range is -40°C to +90°C, which supports use in demanding thermal conditions. That makes it relevant for industrial, embedded, and instrumentation designs with broad ambient variation.

Would this converter make sense for isolated support power in measurement or control electronics?

It is suited to support-power roles where the load is modest, because it provides ±12V constant-voltage output at 1W. The compact form factor also helps in dense control and measurement assemblies.

What are the differences between DPU01L-12, DPU01L-05, and DPU01L-15?

These sibling models all have 1W power and the same 19.5 × 6.1 × 10.2 mm dimensions. The DPU01L-12 is ±12V and ±42mA, the DPU01L-05 is ±5V and ±100mA, and the DPU01L-15 is ±15V and ±33mA.

Can the DPU01L-12 be used in outdoor equipment?

Its temperature rating of -40°C to +90°C supports use in equipment that sees severe temperature conditions. No IP rating is listed, so the provided specs do not confirm protection for direct outdoor exposure.
