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 DLC03C-15 for low-power industrial instrumentation that needs ±15V rails?

This model fits low-power instrumentation, analog, or interface electronics that require constant-voltage ±15V output and stay within 3W. Its specified input range is 36-75VAC, and the listed output current is 100A.

Is the DLC03C-15 suitable for embedded test, monitoring, or control boards?

It can be used in embedded test, monitoring, or control boards that need ±15V output and have a low 3W power requirement. The 21.1 × 13.8 × 8.55 mm package is also useful for compact PCB layouts.

Can this converter fit compact automation electronics where low weight matters?

Its listed weight is 0.0045 kg, and the housing size is 21.1 × 13.8 × 8.55 mm, so it suits compact low-power electronics assemblies. It is intended for applications needing ±15V constant-voltage output from a 36-75VAC input source.

Is the DLC03C-15 suitable for exposed outdoor environments?

The converter is specified for operation from -40°C to +85°C, which supports wide temperature conditions. No IP rating is shown in the specs, so outdoor, wet-location, or dust-tight suitability is not stated.

What is the difference between the DLC03C-15 and its sibling models?

The DLC03C-05, DLC03C-12, and DLC03C-15 all share a 3W rating, 36-75VAC input range, 21.1 × 13.8 × 8.55 mm dimensions, 0.0045 kg weight, and a -40°C to +85°C operating range. Their outputs differ: 5V at 300A for DLC03C-05, 12V at 125A for DLC03C-12, and 15V at 100A for DLC03C-15.
