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-55B typically used for?
The Mean Well ADD-55B is typically used in smaller security and backup-power systems that need a 27.6V main DC output in a dual-output power supply. With 55.12W of rated power and 1.3A on the main 27.6V output, it fits lighter-duty applications where a compact UPS-style supply is sufficient.
Can the ADD-55B support battery-backed security power designs?
Yes. The ADD-55B is positioned as a security power supply with UPS function, so it is suitable for battery-backed DC system designs when the connected load stays within the product's 27.6V, 1.3A, and 55.12W output rating.
Will the ADD-55B run from common 120V and 240V AC mains?
Yes. The listed AC input range is 88-264VAC, so the ADD-55B can operate from common AC mains systems within that range, including typical 120V and 240V supplies. That helps keep deployments flexible across sites.
How does the ADD-55B compare with other ADD series models?
Within the ADD-55 series, the ADD-55B delivers 55.12W with a 27.6V main output at 1.3A, plus a 5V/3A auxiliary output, at 74% typical efficiency. The ADD-55A provides 52.58W with a 13.8V main output at 2.5A and 71% typical efficiency. The choice depends on the main output voltage and battery system your design uses.
