DEVICE FOR TESTING GENERATORS Russian patent published in 2007 - IPC G01R31/34 

FIELD: testing engineering.

SUBSTANCE: device comprises tachometer, ammeter provided with current transducer, and control unit that has power and control transistors and potentiometer. The control unit additionally has second power and control transistors and four separating diodes. The power transistors are interconnected in series to the automotive power supply system. The control transistors are connected in series with the load resistors and are connected with the circuits of the power transistors. The circuits of the control transistors composed of the resistors and separating diodes connected in series are connected to the mid point of the connection of the power transistors and are connected with the terminal of the device which is connected with the terminal of the voltage controller during testing. One lead of the potentiometer is connected with the negative wire, and the second lead is connected with the bases of the power transistors through the other separating diodes.

EFFECT: expanded functional capabilities.
