DESCRIPTION The MCS Series consists of multi-output 24 VAC indoor power supplies. These power supplies provide output for 4, 8, or 16 cameras from a single source and come in 2, 5, 10, and 20 amp capacities. To compensate for voltage losses over long wire runs, 28 VAC outputs are also available on most models. The power supplies allow for 120 or 240 VAC line input.
APPLICATION EXAMPLES Table A contains examples of products and the number of units that can be powered by each power supply, and is based on the vA rating of each product. Table A.
