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 is the Mean Well ADD-55A designed for?
The ADD-55A is a security power supply intended for applications that need a regulated 13.8V main output plus an auxiliary 5V output. Its built-in battery charger with UPS function makes it suitable for security-related systems where power continuity is important.
What are the output ratings of the ADD-55A?
This model provides 52.58W total rated power with a 13.8V main output rated at 2.5A, plus a 5V auxiliary output rated at 3A and a 13.4V battery charging output rated at 0.23A. It is a dual-output power supply, which helps support systems that require two DC output rails from one unit.
Does the Mean Well ADD-55A support backup power applications?
Yes. The ADD-55A is a dual-output supply with a battery charger and UPS function, and an optional DC alarm signal can report AC fail and battery low. That makes it a practical choice for security power applications where backup power support is part of the system design.
What input range does the ADD-55A accept?
The ADD-55A has a universal input range of 88 to 264VAC and also supports 124 to 370VDC input. This wide range helps the same model fit a variety of commercial and industrial power environments.
What protection features are included in the ADD-55A?
This model includes overload and over voltage protection. Overload protection trips at 105% to 150% of rated output power (hiccup mode in AC charging mode, internal fuse in UPS mode), and over voltage protection on CH1 is 14.49V to 18.63V, hiccup mode with automatic recovery.
Is the Mean Well ADD-55A suitable for demanding indoor operating environments?
The unit is rated for operation from -10°C to +60°C with load derating per the derating curve, which gives separate ratings with 18.2CFM min. forced airflow and with no fan. It also meets listed safety and EMC standards including UL62368-1 and EN55032 Class B, which supports use in professional equipment environments.
