Test conditions and notes8
- 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 max., please refer to peak loading curves.
- 7. Derating may be needed under low input voltage. Please check the derating curve for more details.
- 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 I use the SDR-120-24 to power a 24V PLC and I/O system in a control panel?
Yes, this model is a 24V DIN rail power supply rated for 120W and 5A, which fits many 24V PLC, I/O, and control panel loads within that range. Its 125.2 x 113.5 x 40.0 mm housing is a slim format for DIN rail layouts where panel space is limited.
Is the SDR-120-24 suitable for 24V industrial automation controls inside a machine cabinet?
It is intended for DIN rail mounting and provides 24V output up to 5A, so it is appropriate for 24V industrial automation controls that stay within 120W total load. The wide 88-264VAC input also suits panels that may be supplied from different standard AC mains ranges.
Can this power supply be used for a 24V building management or control enclosure?
Yes, the SDR-120-24 is appropriate for 24V building management and control enclosure applications when the connected devices require no more than 120W or 5A. Its DIN rail form factor and 40.0 mm slim profile make it practical for organized cabinet installations.
Is the SDR-120-24 meant for exposed environments or for use inside an enclosure?
This unit is better suited to indoor control cabinets and protected enclosures rather than exposed outdoor mounting. The specified operating temperature range is -25°C to +70°C, and its safety approvals include UL508, TUV BS EN/EN62368-1, AS/NZS 62368.1, EAC TP TC 004 and BSMI CNS15598-1.
How does the SDR-120-24 compare with other Mean Well SDR DIN rail models?
In the SDR-120 series, the related models are the SDR-120-12 at 120W, 12V, 10A (12-14V adjustable) and the SDR-120-48 at 120W, 48V, 2.5A (48-55V adjustable), while the SDR-120-24 delivers 120W at 24V, 5A (24-28V adjustable). All three share the 88-264VAC input with PFC, DC OK relay contact and 40 x 125.2 x 113.5 mm housing; the 24V model has the highest typical efficiency at 91%, versus 89% (12V) and 90.5% (48V).
