The HM8135 is unique in the class of 130W with two 0 to 32V / 2A two-quadrant outputs, which functions both as a current source and sink. The HM8135 is a ""I"" and ""IV"" quadrant power supply unit. Thus you can have both positive as well as negative current (current source / current sink). The devices of 8100 series can be easily integrated in the testing format via the USB interface or RS-232 interface. You can easily arrange powerful measuring stations together with other controllable meters from HAMEG. The device can also be used manually in ""Stand Alone Mode"" manually for pure laboratory use
