Overview

TDR-240-48 is the 48V output model of this series: rated current 5A, rated power 240W, typical efficiency 92%.

TDR-240 is one economical slim 240W Din rail power supply series, adapt to be installed on TS-35/7.5 or TS-35/15 mounting rails. The body is designed 63mm 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-240 is designed with metal housing that enhances the unit's power dissipation. With working efficiency up to 92 %, the entire series can operate at the ambient temperature between -30℃ and 70℃ under air convection. It is equipped with constant current mode for over-load protection, fitting various inductive or capacitive 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 ambient temperature derating of 3.5℃/1000m is needed for operating altitude higher than 2000m(6500ft).
7. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets 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 )

FAQ

Can I use the TDR-240-48 for a 48V PLC or industrial control system?

Yes, if the control system uses 48VDC and the total load does not exceed 5A or 240W. Its 340-550VAC 3 phase input and DIN rail design suit industrial control cabinets that distribute higher-voltage DC power from a three-phase source.

Is the TDR-240-48 suitable for 48V building automation or access control panels?

It can be used where the panel requires a 48VDC supply up to 240W and 5A. The slim 125.2 × 113.5 × 63.0 mm housing and DIN rail mounting are useful in space-constrained building management enclosures.

Can this model power 48V industrial communication or control devices inside an automation cabinet?

Yes, for 48VDC cabinet devices whose combined demand stays within 5A and 240W. The metal case, DIN rail format, and efficiency up to 92% make it a practical option for organized control cabinet layouts.

Is the TDR-240-48 a good choice when I need a slim 48V DIN rail power supply?

This model is intended for that type of requirement, combining 48V output with a compact 125.2 × 113.5 × 63.0 mm body. It provides up to 240W and 5A, which can suit smaller 48V control sections without moving up to the larger 480W or 960W frames.

How does the TDR-240-48 compare with the other TDR models?

The TDR-240-48 is rated at 240W, 48V, and 5A. The related models are TDR-240-24 at 240W, 24V, 10A; TDR-480-24 at 480W, 24V, 20A; 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-240-48 be used in an enclosed industrial cabinet with varying ambient temperatures?

The specified operating range is -30°C to +70°C, which supports use in many indoor industrial enclosures and control cabinets. The listed specs do not provide a separate outdoor enclosure rating, so it is best considered for protected cabinet or enclosure installations.
