Test conditions and notes5
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 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. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 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. 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 AD-155A typically used for?

The Mean Well AD-155A is commonly used in security and backup-power applications that need a stable 13.8V DC output. With 151.55W of output capacity and 10.5A rated current, it fits alarm panels, access control systems, CCTV support equipment, and other low-voltage devices that need battery-backed UPS-style power support.

Can the AD-155A support security systems with battery backup requirements?

Yes. The AD-155A is positioned as a security power supply with UPS function, which makes it suitable for systems where the DC load needs continued support through a battery-backed architecture. The connected load still needs to remain within the unit's 13.8V, 10.5A, and 151.55W output limits.

Will the AD-155A run on standard 120V and 240V AC mains?

Yes. The specified input range is 88-264VAC, so the AD-155A can operate from common 120V and 240V AC mains supplies within that range. That makes it easier to use across different installation environments without changing the power supply model.

Is the AD-155A suitable for outdoor or exposed installations?

The current product data does not show a waterproof IP rating, so it should be treated as an indoor or enclosure-mounted power supply rather than a directly exposed outdoor unit. Its stated operating range is -10°C to +60°C, with load derating at higher ambient temperatures per the derating curve, and the final installation should still provide appropriate environmental protection.

How does the AD-155A compare with other AD series models?

Within the AD-155 series, the AD-155A provides 151.55W at 13.8V and 10.5A. Related models include the AD-155B at 151.55W and 27.6V/5A, and the AD-155C at 156.5W and 54V/2.7A. The main difference is the output voltage and current capacity for the load you need to support.
