Overview

TDR-480-48 is the 48V output model of this series: rated current 10A, rated power 480W, typical efficiency 93%.

TDR-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 3ψ 340VAC to 550VAC (Dual Phase operation possible) and conforms to BS EN/EN61000-3-2, the norm the European Union regulates for harmonic current. TDR-480 is designed with metal housing that enhances the unit's power dissipation. With working efficiency up to 93 %, the entire series can operate at the ambient temperature between -20℃ and 70℃ under air convection. It is equipped with constant current mode for overload protection, fitting various inductive or capacitive applications. The complete protection functions and relevant certificates for industrial control apparatus (UL508, IEC 62368-1 CB approved by UL.) make TDR-480 a very competitive power supply solution for industrial applications.

Test conditions and notes7

1. All parameters NOT specially mentioned are measured at 400VAC 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. Dual phase operation is allowed under certain derating to output load. Please refer to derating curves for details.
5. 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.
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 TDR-480-48 for a 48V industrial control cabinet?

Yes, if the cabinet uses 48VDC and the total load stays within 10A or 480W. Its 340-550VAC 3 phase input and DIN rail format are aligned with industrial control enclosures that distribute 48VDC from a three-phase source.

Is the TDR-480-48 suitable for 48V building automation or control panels with higher current demand?

It can be used where the panel requires 48VDC with up to 480W and 10A available. The slim metal housing and DIN rail mounting make it practical for cabinet-based control systems that need more capacity than a 240W 48V unit.

Can this model support 48V industrial automation equipment inside a DIN rail enclosure?

Yes, for 48V control and automation loads whose combined requirement does not exceed 10A and 480W. The stated efficiency is up to 93%, and the 128.5 × 125.2 × 85.5 mm form factor is designed for DIN rail cabinet layouts.

Is the TDR-480-48 a better fit than a smaller 48V DIN rail supply when more headroom is needed?

For 48V systems, this unit provides 10A and 480W, compared with 5A and 240W on the TDR-240-48. It keeps the same three-phase 340-550VAC input approach while adding output capacity for larger cabinet loads.

What are the differences between the TDR-480-48 and the other TDR series models?

The TDR-480-48 is 480W at 48V and 10A. The rest of the series includes TDR-240-24 at 240W, 24V, 10A; TDR-240-48 at 240W, 48V, 5A; TDR-480-24 at 480W, 24V, 20A; TDR-960-24 at 960W, 24V, 40A; and TDR-960-48 at 960W, 48V, 20A.

Can the TDR-480-48 be used in enclosed industrial cabinets over a wide temperature range?

The operating temperature range is -30°C to +70°C, which supports use in many indoor control cabinets and enclosures. Since the provided data does not list a separate outdoor or exposed-use enclosure rating, it is better matched to protected cabinet environments.
