Overview

NDR-480-24 is the 24V output model of this series: rated current 20A, rated power 480W, typical efficiency 92.5%.

NDR-480 is one economical slim 480W Din rail power supply series, adapt to be installed on TS-35/7.5 or TS-35/15 mounting rails. The body is designed 85.5mm in width, which allows space saving inside the cabinets. The entire series adopts the full range AC input from 90VAC to 264VAC and conforms to BS EN/EN61000-3-2, the norm the European Union regulates for harmonic current. NDR-480 is designed with metal housing that enhances the unit's power dissipation. With working efficiency up to 92.5%, the entire series can operate at the ambient temperature between -20℃ and 70℃ under air convection. It is equipped with constant current mode for over-load protection, fitting various inductive or capacitive applications. The complete protection functions and relevant certificates for industrial control apparatus (UL508, TÜV BS EN/EN62368-1, and etc.) make NDR-480 a very competitive power supply solution for industrial applications.

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. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended.
5. Derating may be needed under low input voltage. Please check the derating curve for more details.
6. 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 )
7. 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).

FAQ

Can I use the NDR-480-24 for a larger 24V PLC or control cabinet build?

Yes, this is the highest-capacity 24V model in the listed group at 480W and 20A output. That makes it suitable for larger PLC or control cabinet builds with heavier 24VDC demand than 120W or 240W DIN rail supplies can cover.

Is the NDR-480-24 appropriate for industrial automation panels with many 24V loads?

It is appropriate for industrial automation panels that run on 24VDC and need up to 20A across multiple loads. Even at 480W, it keeps a DIN rail format and a slim 85.5 mm profile for high-density control cabinet layouts.

Can this model be used for 24V building management panels with higher current demand?

Yes, it can fit building management panels that require 24VDC and draw more current, as long as the system stays within 480W and 20A. The wide 90-264VAC input is also useful for standardized cabinet designs across different AC input environments.

Does the NDR-480-24 belong in an electrical enclosure rather than an exposed location?

Yes, this model is intended for DIN rail mounting in control cabinets and electrical enclosures. Its operating temperature range is -20°C to +70°C and it uses a metal case, but no ingress rating is listed here for direct exposure to weather or washdown conditions.

How does the NDR-480-24 compare with other NDR series power levels and voltages?

Other listed NDR siblings are NDR-75-12 at 75.6W 12V 6.3A, NDR-75-24 at 76.8W 24V 3.2A, NDR-75-48 at 76.8W 48V 1.6A, NDR-120-12 at 120W 12V 10A, NDR-120-24 at 120W 24V 5A, NDR-120-48 at 120W 48V 2.5A, NDR-240-24 at 240W 24V 10A, NDR-240-48 at 240W 48V 5A, and NDR-480-48 at 480W 48V 10A. The NDR-480-24 is the 24V 480W version rated at 20A.
