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-960-24 as a central 24V DC supply in a large PLC control cabinet?

Yes, this model is intended for high-capacity DIN rail applications where a 24V DC bus is needed in one enclosure. It provides 24V at 40A with 960W total output, which makes it suitable for larger PLC and automation cabinets than lower-power SDR models.

Is the SDR-960-24 appropriate for industrial automation panels with many 24V loads?

It is a fit when the total 24V demand across the panel stays within 40A and 960W. Its DIN rail format is designed for cabinet mounting, and the 150.0 x 125.2 x 110.0 mm size should be checked against available panel space.

Can the SDR-960-24 support building management systems with multiple 24V control devices?

It can be used for larger building management enclosures that consolidate many 24V DC devices onto one supply. The key sizing limits are 24V output, 40A current, and 960W total power.

Is this a good choice for a DIN rail cabinet that needs one high-power 24V supply instead of several smaller units?

It can be, especially when the cabinet is already set up for DIN rail hardware and the load is concentrated around one 24V bus. This unit delivers 960W at 24V and 40A from a single supply, with a 3-second peak of 1248W (52A) for short load surges.

Should the SDR-960-24 be used only inside a control enclosure?

Yes, it is best treated as a cabinet-mounted industrial power supply. The product data gives an operating temperature range of -30°C to +70°C, with output derating at higher temperatures per the derating curve, but no IP rating is listed for exposed outdoor or washdown use, so enclosure installation is the safer interpretation.

How does the SDR-960-24 compare with other SDR series models?

The SDR-960 spec sheet covers two models. The SDR-960-24 gives 24V at 40A (960W), adjustable 24 ~ 28V, with 180mVp-p ripple and noise. The SDR-960-48 gives 48V at 20A (960W), adjustable 48 ~ 55V, with 250mVp-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.
