3000mA AC/DC Power Supply/Adapter
Power Supplies are Rated by Power Output Amperage (milliamps)
This is a fixed voltage, universal, AC to DC power supply with output of 12V DC up to 3 amps although we recommend for normal usage to remain below 2.5 amps (2500mA) if the fan units will be run full time.
The DC end of the power supply utilizes a 2-pin female receptacle on the end of a 6' cord. The receptacle plugs directly into most of our products but on the other products (mainly the component cooling units), a 2.1mm Coax plug is used. The power supplies come with several plugs that are color coded but due to inconsistencies in the color coding, find the plug that fits the best, the correct plug will simply fit snuggly into connector. You can also check the packaging as coding should be indicated correctly on the actual package that you receive. Again, you will use the 2.1mm plug when a plug is necessary for our products.
When using the plug, ensure to align 'Tip' to '+' on the ends of the connectors/plugs. If reversed, the units will not be damaged but they simply will not work.
To determine how many units can be powered with a particular power supply, you have to calculate the milliamps of power required for each of the products you wish to power using one power supply. This information is included with each product description (bottom of specs). Calculate the milliamps and then select the appropriate power supply.
