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. The Regulatory Compliance Mark (RCM) is applied on a voluntary basis. The equipment meets the relevant IEC or AS/NZS standards, or AS/NZS 3820 where applicable. The use of the RCM mark complies with AS/NZS 4417.1.
6. Some factory or model may not have the BIS logo, please contact your MEAN WELL sales for more information.
7. 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).
8. 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.

FAQ

What are the main output specifications of the Mean Well XDR-480-48?

The XDR-480-48 is a 480W DIN rail power supply with a 48V DC output. It is rated for 10A output current and is designed for industrial power applications where a compact high-power supply is needed.

What types of applications is the XDR-480-48 suited for?

This model is suited for industrial DIN rail power systems that need 48V DC power in a narrow form factor. Its listed approvals include ITE, industrial, marine DNV, SEMI47, and CID2 HazLoc, making it relevant for demanding commercial and industrial environments.

How slim is the XDR-480-48 compared with typical DIN rail power supplies?

The XDR-480-48 is described as an ultra slim DIN rail power supply with a 48mm width. That narrow profile is a key differentiator for control cabinets or panels where DIN rail space is limited.

What operating temperature range does the XDR-480-48 support?

The listed operating temperature range for the XDR-480-48 is -40 °C to 85 °C. This wide range supports use in industrial environments where ambient conditions may vary significantly.

What input voltage range does the XDR-480-48 support?

The product description lists an 85~305Vac input range, with 277Vac available. This wide AC input range supports use across many industrial power systems and regions.

Can the XDR-480-48 be used in higher-power parallel systems?

Yes, the XDR-480-48 supports parallel operation up to 1920W in a 3+1 configuration. This makes it suitable for applications that need scalable 48V DC power using multiple compatible units.

Does the XDR-480-48 support monitoring or communication features?

Yes, the product description lists a MODBus communication interface for control, setting, and monitoring. This is useful in industrial systems where power supply status and configuration need to be integrated with broader monitoring equipment.

What efficiency and standby characteristics are listed for this model?

The XDR-480-48 is listed with high efficiency up to 96%. The description also notes no-load power dissipation of 1W to 3W by R.C., which can matter in systems where idle power consumption is tracked.

What warranty and physical weight are listed for the XDR-480-48?

The XDR-480-48 has a listed warranty period of 5 years. Its listed weight is 1.1 kg, which is relevant for equipment planning and panel component documentation.
