Test conditions and notes9

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. 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. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
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. 3 seconds peak power max. and the average output power should not exceed the rate power.
7. Derating may be needed under low input voltage. Please check the derating curve for more details.
8. Consult MEAN WELL for deployment of Radiation class B.
9. 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 SDR-960-48 for a 48V industrial control cabinet with higher current demand?

Yes, this model is designed for high-output DIN rail cabinet use where a 48V DC bus is required. It delivers 48V at 20A with 960W total power, which suits larger 48V control systems better than smaller SDR units.

Is the SDR-960-48 suitable for building management or automation panels that run on 48V DC?

It can be a fit when the panel uses 48V DC equipment and the combined load stays within 20A and 960W. The DIN rail format also makes it appropriate for structured enclosure builds rather than bench or open-frame use.

Can the SDR-960-48 power multiple 48V devices in one enclosure?

Yes, as long as the total 48V load remains within 20A and 960W. With dimensions of 150.0 x 125.2 x 110.0 mm, it is better suited to larger control cabinets that can accommodate a high-power DIN rail supply.

Does the SDR-960-48 make sense when a 48V panel needs one centralized DIN rail power supply?

It does when the design goal is to feed a larger 48V DC bus from one supply inside the cabinet. Its 180-264VAC input and 48V, 20A, 960W output make it the 48V model of the SDR-960 series, with a 3-second peak of 1248W (26A).

Can this model be installed in harsh exposed locations, or is it meant for enclosure use?

This unit should be treated as an enclosure-mounted DIN rail power supply. The listed operating temperature range is -30°C to +70°C, with output derating at higher temperatures per the derating curve, but no IP rating is provided for exposed outdoor or direct-spray environments.

How does the SDR-960-48 compare with related SDR DIN rail power supplies?

The SDR-960 spec sheet covers two models. The SDR-960-48 gives 48V at 20A (960W), adjustable 48 ~ 55V, with 250mVp-p ripple and noise. The SDR-960-24 gives 24V at 40A (960W), adjustable 24 ~ 28V, with 180mVp-p ripple and noise. Both share the 180 ~ 264VAC / 254 ~ 370VDC input, PFC (PF≧0.95), 94% typical efficiency, DC OK relay contact, current sharing and the same 110 x 125.2 x 150 mm (W x H x D) case.
