Test system LQ400

Testsystem LQ400 - Serie

The qualification test systems of the LQ400-series are used to test the life time of multiple DUTs at the same time. The main improvements are the implementation of the Xdbus technologie and a trouble-free and cost-saving change-over to other DUTs.

Depending on the size of the DUT, the test system is equipped with:

a) 3 load boxes with 2 DUTs per box,

b) 6 load boxes (in a separate rack) with 1 DUT per box,

c) 6 load boxes (in a separate rack) with 2 DUTs per box,

d) 12 load boxes (in two separate racks) with 1 DUT per box.

The load box is simulating the environment of the car as realistic as possible. Real loads (e.g. motors for power windows) are directly switched from the DUT to qualify. Additional relay cards in the load box allow you to simulate for example to simulate the upper stop position of the power window with parallel resistors to increase the current.

In the qualification test system integrated current measurement cards allow you to measure any current from standby to full load.
