Test conditions and notes5
  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. All the EMC tests are been executed by mounting the unit on a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  5. 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).

FAQ

What types of systems is the ADD-155C designed to power?

The Mean Well ADD-155C is designed for higher-voltage security and backup-power systems that need a 54V main DC output and a dual-output architecture. With 149.9W of rated power and 2.3A on the main 54V output, it is a fit for systems that need UPS-style support on a 54V rail while also benefiting from an auxiliary low-voltage output.

Can the ADD-155C be used in battery-backed DC applications?

Yes. The ADD-155C includes UPS function in the product positioning, so it is intended for battery-backed DC system designs where continuity of power matters. The main connected load should stay within the supply's 54V, 2.3A, and 149.9W rating.

Will the ADD-155C operate from standard AC mains supplies?

Yes. The product data lists an AC input range of 88-264VAC, so the ADD-155C can operate from common 120V and 240V AC mains systems that fall within that range. That makes it easier to deploy across multiple regions or facility standards.

Is the ADD-155C suitable for exposed outdoor use?

The current product data does not list an IP rating for waterproof or outdoor exposure, so the ADD-155C should be installed indoors or inside a suitable protective enclosure. Its listed working temperature is -10°C to +60°C, but the surrounding installation still needs proper environmental protection.

How does the ADD-155C compare with other ADD series options?

The ADD-155C delivers 149.9W with a 54V main output at 2.3A in a dual-output format. The ADD-155B offers a 27.6V main output at 4.5A with similar wattage, while the ADD-155A offers a 13.8V main output at 9.5A, also at 152.75W. The main difference is the output voltage class and available current for the primary load.
