Overview

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

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-480-24 for a larger 24V PLC cabinet with more I/O and control loads?

Yes, this model is suited to 24VDC control cabinets that need more capacity, up to 20A or 480W. Its 340-550VAC 3 phase input and DIN rail format make it appropriate for larger industrial panels fed from three-phase power.

Is the TDR-480-24 appropriate for 24V industrial automation panels with multiple control devices?

It can be a fit when the total 24VDC demand remains within 480W and 20A. The metal case, slim design, and efficiency up to 92.5% support compact enclosure layouts with higher current needs than the 240W versions.

Can this power supply be used for 24V building management panels with several controllers and field devices?

Yes, if the panel runs on 24VDC and the aggregate load stays at or below 20A and 480W. The DIN rail construction and 128.5 × 125.2 × 85.5 mm size make it suitable for control cabinets where a single higher-capacity supply is preferred.

Is the TDR-480-24 a good option when I need more 24V current without going to the 960W frame?

This model sits in the middle of the series at 24V, 20A, and 480W. It offers more output than the 24V 240W unit while keeping a smaller footprint and lower weight than the 24V 960W model, which is 2.47 kg.

How does the TDR-480-24 compare with the other TDR series power supplies?

The TDR-480-24 is rated at 480W, 24V, and 20A. The sibling models are TDR-240-24 at 240W, 24V, 10A; TDR-240-48 at 240W, 48V, 5A; TDR-480-48 at 480W, 48V, 10A; TDR-960-24 at 960W, 24V, 40A; and TDR-960-48 at 960W, 48V, 20A.

Can the TDR-480-24 be used inside a control enclosure with demanding ambient conditions?

The specified operating temperature is -30°C to +70°C, which supports use in many industrial cabinets and enclosed panels. The provided specs describe a metal case but do not list a separate exposed-location enclosure rating, so cabinet or enclosure use is the safer fit.
