TRANSIENT IMMUNITY TEST GENERATOR CAR-TG 20

General:

The transient generator CAR-TG 20 is designed according to strict specifications of Ford standards. As per standards FORD FMC1278 and EMC-CS-2009.1 the transient tests defined in RI130, CI220, and CI 260 are generated by CAR-TG20. By that is meant pulse forms: A1, A2-1, A2-2, C-1, C-2, and F. Therefore, a specified 12VAC Potter & Brumfield relay as well as other parts defined by standard create pulses which are close to real appearing transients.

A microprocessor-controlled 7" touch screen display unit is integrated and permits easy operation of the generator. The following parameters can be selected and varied:

Depending on parameters selected, the internal SW0-SW4 of the standard are switched automatically, its state is also displayed in the screen. Modes M1 (rectangle) and M2, M3 (pseudo-random rectangle) are generated internally.

The CAR-TG 20 offers a battery Input on the left. Outputs for the DUT for pulse A1, A1-1, A1-2, C-1, and F are located on the right side. As well a coaxial bridge can be set between Terminal Pulse C and Sink to define Test CI200 or RI130.

For maintenance reasons, the Potter & Brumfield relay is easy to reach and changeable. Therefore a test time counter on that device is available to detect the end of life of that component. A reset button of that timer is also present.

The CAR-TG 20 excels by its compact design, simple handling, and precise reproducibility of test impulses.
