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 is the Mean Well XDR-75-48LA used for?

The XDR-75-48LA is a 48V industrial DIN rail power supply for control cabinets, automation equipment, and other B2B industrial power systems. Its ultra slim 30mm width makes it suitable for panels where DIN rail space is limited.

What are the main output ratings of the XDR-75-48LA?

This model is rated for 74.88W of output power at 48V DC. Its rated output current is 1.56A.

Is the XDR-75-48LA suitable for demanding industrial environments?

Yes. The XDR-75-48LA is specified for operation from -40°C to 85°C and includes protections for short circuit, overload, over voltage, and over temperature conditions. It also carries industrial-related approvals listed in the product data, including 61558-1/-2-16, 61010, SEMI47, CID2 HazLoc, and Marine DNV.

How efficient is the Mean Well XDR-75-48LA?

The XDR-75-48LA has efficiency up to 91%, based on the listed product specifications. It also has low no-load power dissipation of 1W to 1.5W by remote control.

What makes the XDR-75-48LA different from a standard DIN rail power supply?

This model is positioned as a high-end ultra slim industrial DIN rail power supply with a 30mm width. It also supports a wide 85 to 305Vac input range, 200% peak power capability, and 600% transient peak current capability, which can matter in industrial systems with short-duration load surges.

Can the XDR-75-48LA be used in systems with 277Vac input?

Yes. The listed input range is 85 to 305Vac, and the product data specifically notes that 277Vac is available. This makes it suitable for applications where that AC input level is required.

What warranty does the XDR-75-48LA include?

The XDR-75-48LA includes a 5-year warranty period. This is useful for buyers evaluating lifecycle support for industrial power supply installations.
