1
Test supply output
At this output the generator can be loaded with the maximum current of 15A // 30A // 35A // 50A // 100A
depending on the type of generator. This output is also used for the internal wiring in a complete rack system
installation.
2
Reference earth connection
During immunity tests it may be useful to connect the simulator with reference earth plane of the test set-up.
For complete rack installations all different test generators shall be grounded at this point.
3
Analogue input 0-10V
The internal amplifier can be controlled by an external signal generator. The operator therefore shall select
the User Test Routines of the VDS part and start the menu Extern. The amplifier than is ready to be remote
controlled.
The input signal range is 0-10V in the frequency range of 0-50kHz. The output power (EUT test supply) than
would result in 0-30V or 0-60V and a nominal current depending on the type of instrument. The frequency
range is 50kHz for up to 6Vpp and 25kHz for up to 16Vpp.
For Frequency >50kHz to 100kHz the VDS output voltage must be limited to max. 3Vpp.
Therefore the analogue input signal must be limited to max. 0.7Vpp !
4
External trigger
One single event with preselected parameters can be released. Trigger level is 5-15V positive going.
5
Mains input
230V 16A input connector. This connector depends on the VDS model
6
Fuses
This fuses depends on the VDS model. F4 is the control fuse (2Aslow blow) for units with 3-phase supply.
7
Power On switch
230V system: The Power On switch includes also the power mains fuses (2 x 10A T) and filter unit.
115V system: The Power On switch, fuses and the filter unit are separated due to the higher currents.
For high current generators a 3phase power mains supply has to used.
