This is a fixed voltage power supply 12 V DC. This unit plugs into a standard US 110/120V AC receptacle.  This power supply is ideal and recommended when using the Advanced Lt controller as operating our products at 12V, most of the products will be audible but may be acceptable and even desirable when components are installed in a closet or cabinet and this is also when components require more airflow and when noise is not as big of a factor.

The DC end of the power supply utilizes a 2-pin female receptacle on the end of a 4' cord.  The receptacle plugs directly into most of our products but on the other products (mainly the metal, cooling units), a 2.1mm Coax plug is used (not included). 

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.

Technical Notes

• Hot Power Supply.  Power supplies do get warm in normal applications, however, if the unit gets too hot, you should unplug it and get a larger power supply (more milliamps) as the power supply may be overloaded.
• Testing the Unit.  This unit, when not under load, will read up to 18V DC on a voltmeter.
