Frequently Asked Questions

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.

Is the ADD-55B a better fit for lower-power 27.6V loads than the ADD-155B?

Yes, when the load is relatively small. The ADD-55B provides a 27.6V main output like the ADD-155B, but at 55.12W and 1.3A rather than 152.75W and 4.5A. That makes the ADD-55B a better fit when you need the same output class without the larger power capacity.

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?

The ADD-55B is the smaller option in this group, delivering 55.12W with a 27.6V main output at 1.3A in a dual-output design. The ADD-155B provides 152.75W at 27.6V and 4.5A, while the ADD-155C provides 149.9W at 54V and 2.3A. The choice depends on the main output voltage you need and how much power margin your system requires.
