Frequently Asked Questions
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 described as a security power supply with 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 smaller ADD-55B provides 55.12W with a 27.6V main output at 1.3A. Selection depends on whether you need the 27.6V or 54V output class and how much current headroom your application needs.
