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-480-48 power a 48V PLC or industrial automation panel?

Yes. The SDR-480-48 is a 48V DIN rail power supply rated for 480W and 10A, which fits 48V control panels, PLC cabinets, and industrial automation assemblies that need that voltage and current capacity. Its DIN rail form factor also suits panel layouts where organized cabinet mounting is required.

Is the SDR-480-48 suitable for 48V building management and control cabinets?

It can be used in 48V building management and control cabinet applications that require up to 480W and 10A output. The unit accepts 90-264VAC input and is built as a DIN rail industrial power supply, so it matches centralized cabinet power designs using standard AC mains input.

Can I use the SDR-480-48 for 48V relays, controllers, and panel devices in one enclosure?

Yes, if the combined 48V load stays within 480W and 10A. This model is intended for DIN rail mounting, so it fits multi-device control enclosures where several 48V panel components are powered from one cabinet supply.

Which SDR series models are available if I need a different voltage or power level than the SDR-480-48?

The SDR-480 series datasheet lists one other model: the SDR-480-24 at 480W, 24V, 20A (adjustable 24 ~ 28V). It shares the same 90-264VAC input, 94% typical efficiency, 720W (3 sec.) peak power and 85.5 x 125.2 x 128.5 mm housing as the SDR-480-48.

Is the SDR-480-48 meant for open environments or for use inside a control cabinet?

This model is generally suited to control cabinet and enclosure use, with an operating temperature range of -25°C to +70°C (refer to the derating curve). Its industrial DIN rail format and 85.5 x 125.2 x 128.5 mm (W x H x D) size make it a cabinet-mounted power supply rather than a free-standing open-environment unit.
