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-15 to power a 15V control circuit in industrial equipment?

Yes, this converter is intended for constant-voltage 15V output applications up to 3W. It accepts 18-36VDC input and provides 15V output with a listed 200mA output current, which makes it suitable for low-power 15V control or signal circuits within that input range.

Is the SLC03B-15 suitable for embedded 15V electronics inside a compact system?

It can fit space-constrained embedded designs because the body is 22.1 × 13.8 × 8.55 mm and weighs 0.0045 kg. The unit is a 3W constant-voltage converter, so it is best matched to low-power 15V electronics rather than higher-load subsystems.

Can this DC-DC converter be used in automation panels that have 18-36VDC available?

Yes, if the panel provides 18-36VDC and the load needs a regulated 15V constant-voltage output within the converter's 3W rating. Its compact size also helps where board or enclosure space is limited.

Is the SLC03B-15 appropriate for harsh temperature environments?

It is rated for operation from -40°C to +85°C, with load derating at the upper end per the derating curve, so it covers a wide temperature range for industrial and embedded environments. No IP rating is listed, so outdoor or washdown use should not be assumed from the provided specs alone.

How does the SLC03B-15 compare with the other SLC03B models?

All three SLC03B models are 3W DC-DC converters in the same series. The SLC03B-05 provides 5V output with a listed 600mA output current, the SLC03B-12 provides 12V with 250mA, and the SLC03B-15 provides 15V with 200mA.
