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 0.1uf & 47uf 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 a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
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 Mean Well TDR-960-48 to power a 48V PLC or industrial automation control panel?

Yes. The TDR-960-48 provides a 48V DC output at up to 20A with 960W capacity, which fits 48V PLC, controller, and industrial automation panel loads within that power budget. Its DIN rail form factor and slim metal case are suited to control cabinet installations where space is limited.

Is the TDR-960-48 a good fit for 48V building management and control cabinet systems?

It can be a good fit for 48V building management equipment installed in a control cabinet or enclosure. This model delivers 48V, 20A, and 960W, uses a DIN rail mounting format, and supports a 340-550VAC input range for three phase industrial power environments.

Can this 48V DIN rail power supply be used in large industrial control panels with multiple 48V loads?

Yes, if the combined load stays within 48V, 20A, and 960W. The TDR-960-48 is designed as a DIN rail power supply with a slim 110.0 × 125.2 × 150.0 mm housing, which helps when cabinet space is tight. Its efficiency is rated up to 94.5%, which is relevant in higher-power enclosed panel builds.

Is the Mean Well TDR-960-48 suitable for 48V industrial automation systems that need a three phase input power supply?

Yes. This model is built for three phase input and accepts 340-550VAC, making it suitable for industrial automation systems that are powered from that input range. On the output side, it supplies 48V DC up to 20A with 960W total power.

Can the TDR-960-48 be used inside an enclosure or control cabinet in demanding temperatures?

It is intended for industrial use in a control cabinet or enclosure, not exposed outdoor use. The operating temperature range is -30°C to +70°C, and the metal case, DIN rail format, and 2.47 kg build are aligned with enclosed industrial panel environments.

What is the difference between the TDR-960-48 and other Mean Well TDR series DIN rail power supplies?

Within the same series, the TDR-240-24 is 240W, 24V, 10A; the TDR-240-48 is 240W, 48V, 5A; the TDR-480-24 is 480W, 24V, 20A; the TDR-480-48 is 480W, 48V, 10A; and the TDR-960-24 is 960W, 24V, 40A. The TDR-960-48 is the 960W, 48V, 20A model in that group.
