The 1507 is designed to provide isolated AC output variable form 0 to approximately 150 Volts. It can supply a continuous 10Amp output current to a maximum of 1300VA. The output current can be set to the maximum output desired, at which point a latching relay will open circuit and reduce output volts and amps to zero. Two parallel, three prong AC sockets are provided to allow the operator to use the unit for more than one load.

The 1507 also includes a leakage tester that can measure AC leakage current in electrical/electronic equipment in order to verify if the leakage is within limits established by UL, CSA. An audible alarm warns of "HOT" chassis or shorts to exposed metal on equipment under test. The 1507 is supplied with two 3 1/2 meters. One monitors line or output voltage and the other can display output current or leakage.
