AMETEK CTS Automotive Transient Immunity Testing
1.00 14 / 26
4.2. Rear view 19” units
Mains selector 115V / 230V
Reference earth connection
AUX Pulse input from ext. LD
Control input for ext. LD
Parallel interface GPIB / IEEE 488
Remote control connector CN
1 Supply input
Most generators have one or more inputs for the DC voltage. Pulses (transients) will be superimposed on
battery supply voltage or created from this (PFM/PFS)
2 Reference ground connection
The generator has to be connected to the reference ground plane of the test set up.
3 Pulse input for one external generator
The UCS 200N includes a central coupling matrix. The pulse output of an external Load Dump LD200
generator can be connected to this input. The Load Dump pulses then will be available at the central DUT
output at the front panel of the UCS 200N
4 Control input for one external generator
The UCS 200N includes a central coupling matrix. The control output of the external generator can be
connected to this input. The external generator is able to control the UCS200 coupling network.
5 External impedance
Some generators support an external resistor, which can be added to achieve impedance additional to those the
generator includes. Select the “External Rs” mode in the setup menu.
6 External trigger
One single event, burst, surge, voltage dip can be released. Trigger level 5-15V positive going.
7 Warning lamp control
Some generators support a relays contact to control warning lamps which may be installed in the test set-up
(Test On).
8 Safety circuit
To connect an external security circuit whenavailable.
9 Mains selector
Selection of 115V / 230V
10 Power on switch
The switch is part of the mains filter. Mains fuses are part of the filter. (230V / 1A and 115V / 2A)
