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 SPUN02M-05 to derive 5V for a PLC accessory or logic interface from a 10.8~13.2V source?

Yes, this model is built for 10.8~13.2V input and provides a fixed 5V output at 2W. That makes it a fit for low-power PLC accessory boards, logic interfaces, and similar control electronics that need a 5V rail, keeping in mind it is unregulated (10% load regulation).

Is the SPUN02M-05 a good fit for embedded 12V-system electronics that need 5V power?

It is intended for that kind of voltage conversion because the specified input range is 10.8~13.2V in and the output is a fixed 5V. The 2W rating means it is aligned with low-power embedded electronics rather than higher-power 5V devices.

Can this model be used in low-power industrial monitoring or automation boards?

Yes, the fixed 5V output and 2W power rating suit compact monitoring, control, and embedded automation boards. Its 19.6 × 7.2 × 10.2 mm (L × W × H) size is also useful where PCB area is tight.

Is the SPUN02M-05 suitable for indoor panels versus exposed outdoor equipment?

Its operating temperature range is -40°C to +105°C, with load derating at high ambient per the derating curve, so the temperature spec supports demanding indoor industrial environments. No IP rating is provided, so these specs do not support treating it as an exposed outdoor-rated converter.

What is the difference between the SPUN02M-05 and the other SPUN02M versions?

All three listed SPUN02M models are 2W converters in the same series. The outputs differ by model: SPUN02M-05 is 5V with 0~400mA output current, SPUN02M-12 is 12V with 0~167mA, and SPUN02M-15 is 15V with 0~134mA.
