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 peak power max. and the average output power should not exceed the rate power.
  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-480P-48 be used in 48V industrial control panels?

Yes. The SDR-480P-48 is a 48V DIN rail power supply rated for 480W and 10A, so it fits 48V industrial control panels and automation cabinets that require that output level. It is intended for organized DIN rail mounting within the panel.

Is the SDR-480P-48 suitable for 48V building management systems?

It can be used where a building management or centralized control system requires 48V output up to 10A and 480W. The unit also accepts 90-264VAC input, which supports common AC-fed control cabinet designs.

Can I use the SDR-480P-48 to power several 48V cabinet devices from one source?

Yes, as long as the combined load stays within 48V, 10A, and 480W. That makes it relevant for enclosures containing multiple 48V controllers, relays, and automation devices that share a DIN rail power source.

What other SDR models should I look at if I need a different voltage or capacity than the SDR-480P-48?

On the SDR-480P series datasheet, the alternative is the SDR-480P-24 at 480W, 24V, 20A (adjustable 24-28V). For more capacity, the series supports current sharing: up to 8 units can be paralleled (up to 3840W in a 7+1 arrangement), with total output current limited to rated current × number of units × 0.9.

Is the SDR-480P-48 appropriate for enclosed cabinet operation in industrial settings?

Yes, it is suited to enclosed control cabinet use within its -25°C to +70°C operating temperature range, with output derating at higher temperatures per the derating curve. The 85.5 × 125.2 × 128.5 mm (W × H × D) DIN rail housing is built for cabinet mounting rather than bench-top or exposed-location use.
