Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Harmonic current test at 90% load for HDR-100-xxN.
5. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).
7. Some models may not have the BIS logo, please contact your MEAN WELL sales for more information.

FAQ

What 24V applications is the HDR-100-24N sized for?

At 100.8W and 4.2A on a 24VDC bus, the HDR-100-24N can power PLC backplanes, distributed I/O racks, field devices, and small HVAC/BMS controllers mounted in DIN rail enclosures. The slim step-shape profile keeps panel layouts compact.

How does the HDR-100-24N differ from the standard HDR-100-24?

The HDR-100-24N is rated 100.8W / 4.2A versus the HDR-100-24 at 92W / 3.83A. Both use the same 70 × 90 × 54.5 mm (W × H × D) housing and 85–264VAC input; the sheet lists UL508 and LPS for the Blank type (HDR-100-24) only.

Does the HDR-100-24N accept both 120V and 240V mains?

Yes, its 85–264VAC universal input accommodates both North American 120V and European/international 240V mains without requiring input voltage selection. This makes it suitable for global panel builds.

What are the enclosure requirements for the HDR-100-24N?

The HDR-100-24N is designed for installation inside a control cabinet or enclosure and does not carry an IP rating on its own. Operating temperature is -30°C to +70°C (derated at high ambient per the derating curve) at 20–90% RH non-condensing, which suits indoor and protected enclosure deployments.
