Test conditions and notes5
- 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. 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. 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 is the ADD-155B typically used for?
The Mean Well ADD-155B is typically used in security and backup-power systems that need a 27.6V main DC output and benefit from a dual-output design. With 152.75W of rated power and 4.5A on the main 27.6V output, it is a fit for higher-voltage DC loads in systems where an auxiliary low-voltage rail is also useful.
Is the ADD-155B suitable for battery-backed UPS-style DC systems?
Yes. The ADD-155B is a dual-output power supply with a battery charger (UPS function), so it is intended for DC systems that combine normal operation with battery-backed support. The primary connected load should stay within the unit's 27.6V, 4.5A, and 152.75W output capability.
Does the ADD-155B support common 120V and 240V AC input ranges?
Yes. The specified AC input range is 88-264VAC, which allows the ADD-155B to operate from common 120V and 240V mains supplies within that range. That flexibility is useful when standardizing installations across different sites.
Can the ADD-155B be mounted in exposed outdoor conditions?
The current product data does not show a waterproof IP rating, so the ADD-155B should be treated as an indoor or protected-enclosure power supply rather than a unit for direct outdoor exposure. Its listed working temperature is -10°C to +60°C, but enclosure protection should still match the environment.
How does the ADD-155B compare with other ADD series models?
The ADD-155B provides 152.75W with a 27.6V main output at 4.5A in a dual-output design. In the same family, the ADD-155C provides 149.9W with a 54V main output at 2.3A, while the ADD-155A provides 152.75W with a 13.8V main output at 9.5A. Selection depends on which main output voltage class you need and how much current headroom your application needs.
