Test conditions and notes5

1.All parameters are specified at normal input(F:24Vdc, G:48Vdc, H:110Vdc), 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 0% 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 RSDW20H-15 to supply 15V instrumentation or analog control circuits?

Yes, when the equipment needs a regulated 15V output and the load stays within 1.33A and 20W. This unit is a constant-voltage converter designed for applications using a 43-160Vdc input source.

Is this model suitable for 15V industrial communication or interface modules?

It can be used for 15V communication or interface modules as long as the required current does not exceed 1.33A and total power remains within 20W. The 3KVDC input-to-output isolation may also be relevant where isolation is required by the system design.

Can the RSDW20H-15 power compact embedded or automation loads where space is tight?

It is often a practical fit for compact equipment because it delivers 15V at up to 1.33A in a 50.8 × 25.4 × 10.2 mm package. The 2" × 1" footprint and 10.2 mm height also align with space-constrained designs.

How does this converter handle cold or high-heat environments?

The specified operating range is -40°C to +85°C, so it is intended for use across a wide temperature span within those limits. Since no IP rating is listed, environmental exposure protection has to come from the surrounding enclosure.

How does the RSDW20H-15 differ from the 5V and 12V versions?

All three RSDW20H versions share 20W power, 43-160Vdc input, 50.8 × 25.4 × 10.2 mm dimensions, 0.035 kg weight, and -40°C to +85°C operating range. The output ratings are different: the -05 is 5V at 4A, the -12 is 12V at 1.67A, and the -15 is 15V at 1.33A.
