The MA-1000 plugs into a standard US 110V outlet and provides and unregulated 12VDC output with the ability to supply up to 1 AMP of current. It has a 2.1 mm x 5.5 mm barrel connector with the center being the positive connection. It is the standard power adapter used for the dataTaker family of data loggers. It can also be used to provide power for many other data loggers and sensors that can accept an unregulated 12 volt DC input. If necessary, the connector can be easily removed to provide bare wire connections for devices with screw terminal connections for the power.
