Test conditions and notes6

1.All parameters are specified at normal input(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)
6.An external input filter capacitor is required if the module has to meet BS EN/EN61000-4-4, BS EN/EN61000-4-5. The filter capacitor Power Mate suggest: 220uF/100V.

FAQ

Can I use the SLC03B-12 for 12V control or automation subcircuits?

This converter delivers constant voltage 12V output at 3W, which fits low-power control or automation subcircuits needing regulated 12V. Its specified input range is 18-36VDC.

Is the SLC03B-12 a good fit for embedded 12V electronics in compact industrial equipment?

It is designed for compact assemblies, with dimensions of 22.1 × 13.8 × 8.55 mm and a weight of 0.0045 kg. The unit provides 12V constant voltage output and is rated for 3W.

Can this model be used for small 12V interface or signaling modules?

It can be used for low-power 12V interface or signaling modules where constant voltage output is required. The application needs to stay within the 3W rating and use an 18-36VDC input source.

Does the SLC03B-12 support operation across a wide temperature range?

Yes. The listed operating temperature range is -40°C to +85°C, with load derating at the upper end per the derating curve, so it is specified for broad temperature variation. The specs shown do not include an IP rating.

Is the SLC03B-12 suitable for outdoor use?

The available environmental data includes a -40°C to +85°C operating range, but no IP rating is listed. Without a stated IP rating, the product's resistance to dust or water exposure is not defined in the provided specs.

What are the main differences between the SLC03B-12 and its siblings?

The SLC03B-12 is 3W with 12V output and 250mA output current. In the same series, the SLC03B-05 is 3W with 5V output and 600mA output current, while the SLC03B-15 is 3W with 15V output and 200mA output current. All use the same 18-36VDC input range.
