Test conditions and notes9

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. When the temperature is between -40 ° C and -20 ° C and the input voltage is between 85V and 90V, the temperature derating curve drops to 40% .
5. 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).
6. 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.
7. 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 )
8. 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.
9. Some factory or model may not have the BIS logo, please contact your MEAN WELL sales for more information.

FAQ

What are the main output specifications of the Mean Well XDR-120E-12?

The XDR-120E-12 is rated for 120 W output power with a 12 V DC output. Its rated output current is 10 A, making it suitable for 12 V DC loads within that power range.

What type of applications is the XDR-120E-12 intended for?

This model is an ultra slim DIN rail power supply for industrial and B2B power applications. Its 12 V, 120 W output and slim 30 mm width make it a good fit where panel space is limited and regulated DC power is required.

What makes the XDR-120E-12 different from wider DIN rail power supplies?

The XDR-120E-12 has a 30 mm slim-width design, which helps reduce space usage in DIN rail layouts. It still provides 120 W of output power at 12 V, so it is useful when both compact size and meaningful power capacity are important.

What operating temperature range does the XDR-120E-12 support?

The XDR-120E-12 is specified for operation from -40°C to +70°C. The product data notes derating above +50°C, so available output capacity may be reduced at higher ambient temperatures.

How efficient is the Mean Well XDR-120E-12?

The XDR-120E-12 has a typical efficiency of 89%. It also has no-load power consumption of 0.6W at 115Vac and 0.9W at 230Vac, which helps reduce standby energy use when the connected load is minimal.

What input voltage range does the XDR-120E-12 accept?

This model supports an 85 to 264 Vac input range. That wide AC input range makes it suitable for use across many standard AC supply environments, subject to the product's listed certifications and ratings.

What protections are included with the XDR-120E-12?

The XDR-120E-12 includes protection against short circuit, overload, over voltage, and over temperature conditions. It also has a built-in constant current limiting circuit.

Does the XDR-120E-12 use a fan for cooling?

No, the XDR-120E-12 uses a fanless design. Cooling is by free air convection, which can be useful in applications where lower maintenance and reduced moving parts are preferred.

What warranty and weight are listed for the XDR-120E-12?

The XDR-120E-12 has a listed warranty period of 3 years. Its listed weight is 510g.
