AMETEK CTS VDS 200Q Series
Manual for Operation V 1.3.1 25 / 36
As the VDS 200Q series is capable of negative voltages, care should be taken that the VDS 200Q is not used in
the negative voltage range when a PFS 200N or LD 200N are connected. A setting is available to avoid
overvoltage or undervoltage.
CAUTION:
Producing negative voltages with the VDS 200Q will damage the PFS 200N or LD 200N!
The user must disconnect the PFS 200N and LD 200N before performing tests that require
negative voltages!
The maximum current that can be fed back from the DUT is equal to the maximum rating of the amplifier. For
example, the VDS 200Q200.2 can source 200A permanently, or accept 200A return current permanently up until
temperature shutdown.
Several redundant temperature-monitoring functions control the fans in multiple steps. A final “temperature
shutdown” is also implemented to prevent damage due to overheating, but should generally not be seen in
normal use in laboratory conditions.
Many sources are specified in Watts where the output current is dependent on the output voltage VDS 200Qxx.2
are unique in that they are specified in voltage and current only and therefore can provide up to the maximum
current of the VDS from near zero volts up to the full 80V.
As mentioned above, there is no restriction of using the full voltage range over the entire frequency bandwidth.
