Discover the MEAN WELL AD, ADD, and ADS series—specialized AC/DC power supplies with dual and triple outputs designed specifically for security, access control, and CCTV applications . These compact enclosed power supplies provide 2 or 3 independent output channels from a single unit, simplifying installation and reducing costs for multi-voltage security systems . Universal AC input 85-264VAC with high efficiency up to 88% and no-load power consumption <0.75W .
Available models include:
-
AD series: 35W-155W, dual outputs (12V/24V combinations) with battery charging function
-
ADD series: 35W-75W, dual outputs for door access control systems
-
ADS series: 40W-60W, triple outputs for security systems requiring multiple voltages
Key features include battery reverse polarity protection, temperature compensation (via external NTC), and comprehensive protections (short circuit/overload/over voltage) . Operating temperature -20°C to +60°C with free air convection cooling. 3-year warranty. Ideal for access control panels, CCTV cameras, fire alarm systems, and central monitoring stations .
