Mean Well ADD-155A Security Power Supply 152.75W 13.8V 5V 9.5A - UPS, Dual output

The ADD-155A is a dual-output security power supply with a 13.8V output and a 5V output. Its total rated power is 152.75W, and the listed rated current is 9.5A at the main 13.8V output. This makes it suitable where both primary security-system power and an auxiliary low-voltage rail are needed from one unit.

Yes. This model is specifically positioned as a security power supply and is well suited to enclosed security power applications such as alarm, access control, and CCTV power systems. Its 13.8V output and UPS feature make it a strong fit for systems that need stable DC power with backup capability.

Yes. The ADD-155A is listed as a UPS model and includes battery low protection and battery polarity protection. That makes it relevant for security applications where maintaining output during mains interruption is an important requirement.

The ADD-155A accepts a universal 88 to 264VAC input range and also supports 124 to 370VDC input. This wide range helps it fit projects deployed across different mains environments without needing a region-specific AC input version. It also includes active PFC.

This model has a specified working temperature range of -10°C to +60°C, subject to the manufacturer's derating guidance. Cooling is by free air convection rather than forced fan cooling. Buyers should also note the compact 199 x 110 x 50 mm enclosure size when reviewing panel or cabinet space.

The main difference is that the ADD-155A combines dual outputs and UPS-oriented security features in one unit. Compared with a basic single-output supply, it is better suited to systems that need a 13.8V primary rail, a 5V auxiliary rail, and battery-related protection features. That can simplify product selection for security-focused builds.
