Test conditions and notes8
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 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. 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. 6. 3 seconds max., please refer to peak loading curves.
  7. 7. Derating may be needed under low input voltage. Please check the derating curve for more details.
  8. 8. 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 the SDR-75-12 be used for 12V PLC I/O and small control panels?

Yes. The SDR-75-12 delivers 12V at up to 6.3A with 75.6W total output, which fits smaller PLC I/O groups, relays, and control panel assemblies that run on 12V DC. Its DIN rail design also makes it suitable where panel space is limited.

Is the SDR-75-12 suitable for compact industrial automation cabinets?

It is a practical choice for compact automation cabinets that need a 12V DIN rail supply up to 75.6W and 6.3A. The slim 32 mm width helps when rail space is tight; depth is 102 mm.

Can I use the SDR-75-12 in a building management enclosure with 12V control devices?

Yes, if the 12V control load remains within 6.3A and 75.6W. Its 88-264VAC input range supports common AC-fed control enclosures, and the slim 32 mm wide housing suits DIN rail mounting in space-constrained panels.

How does the SDR-75-12 compare with other Mean Well SDR DIN rail power supplies?

Within the SDR-75 series, the siblings are the SDR-75-24 at 76.8W, 24V, 3.2A and the SDR-75-48 at 76.8W, 48V, 1.6A. The SDR-75-12 provides 75.6W at 12V, 6.3A, and all three share the 88-264VAC input, 32 mm wide DIN rail housing, and 112.5W peak power for up to 3 seconds.

Is the SDR-75-12 intended for control cabinet use in challenging temperatures?

Yes. It is rated for operation from -30°C to +70°C, with output derating at higher ambient temperatures per the derating curve, which suits a wide range of indoor cabinet conditions when ambient temperature is controlled within that range. The DIN rail form factor also aligns with enclosed control cabinet installation.
