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 outputs does the Mean Well ADD-155A provide?
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.
Is the ADD-155A suitable for security and access control applications?
Yes. This model is a dual-output power supply with a built-in battery charger (UPS function), which suits enclosed security power applications such as alarm, access control, and CCTV power systems. Its 13.8V output and UPS function make it a strong fit for systems that need stable DC power with backup capability.
Does the ADD-155A support battery-backed or UPS-style operation?
Yes. The ADD-155A includes a battery charger with UPS function and has battery low protection (10V ±0.8V). That makes it relevant for security applications where maintaining output during mains interruption is an important requirement.
What input range does the ADD-155A support?
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 a PFC circuit, with a typical power factor above 0.92 at full load.
What operating environment is the ADD-155A designed for?
This model has a specified working temperature range of -10°C to +60°C, subject to the manufacturer's derating curve. The unit has no built-in fan; the derating curve rates it with an external airflow of at least 21.6 CFM (fan at 10cm), and the output must be derated further without a fan. Buyers should also note the compact 199 x 110 x 50 mm enclosure size when reviewing panel or cabinet space.
Why choose the ADD-155A instead of a single-output power supply?
The main difference is that the ADD-155A combines dual outputs and a battery charger with UPS function 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 charging with battery low protection. That can simplify product selection for security-focused builds.
