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 DLC03B-15 for low-power industrial analog circuits that need ±15V output?

This converter is intended for low-power applications that need constant-voltage ±15V output and stay within a 3W power rating. Its specified input range is 18-36VAC, and the listed output current is 100A.

Is the DLC03B-15 suitable for embedded measurement or instrumentation boards?

It can fit embedded measurement or instrumentation boards that require ±15V rails and do not exceed 3W. The unit is also compact at 21.1 × 13.8 × 8.55 mm, which helps in dense board-level layouts.

Can this model work in small automation interface modules that need ±15V power?

Yes, for low-power automation interface circuits that need constant-voltage ±15V output from an 18-36VAC input source. Its 0.0045 kg weight and small package make it suitable where space and mass are constrained.

Can the DLC03B-15 be used in wide-temperature industrial equipment?

The operating temperature range is specified as -40°C to +85°C, so it is designed for broad indoor equipment temperature conditions. No IP rating is provided in the specs, so outdoor exposure suitability is not stated.

How does the DLC03B-15 compare with the other DLC03B converters?

The DLC03B-05, DLC03B-12, and DLC03B-15 share the same 3W rating, 18-36VAC input range, 21.1 × 13.8 × 8.55 mm dimensions, 0.0045 kg weight, and -40°C to +85°C operating range. The main difference is output: 5V at 300A for DLC03B-05, 12V at 125A for DLC03B-12, and 15V at 100A for DLC03B-15.
