Tailored Models
If any application requires a selection of range, bias or gain
not available with standard models, then any of these parameters
may be independently tailored as required. The range can be any
voltage from zero volts to 800V. The bias can be any voltage
from zero volts to 800V and must be lower or equal to the range.
The gain can be any value between 5 and 450; however, the
maximum signal input voltage of ±15VDC
must be considered. With this flexibility, any input signal
range including positive or negative unipolar ranges can be
matched for optimum performance with any stack voltage up to
800V. As an example, if the required range is 800V, the bias is
zero volts and the gain
is 100, then a unipolar input signal change from zero volts to
+8V will result in an output stack voltage change from zero volts
to +800V. In this case, a signal input voltage of +4V will
maintain the stack at the midpoint of its displacement.
Model Number Assignment To define a model number for a specific tailored
unit, change the suffix as follows:
Model Suffix
The first two numbers of the suffix specify the
input powereither 48VDC or 24VDC.
The third letter specifies the gain of the
amplifier according to the code list below:

The fourth and fifth numbers
specify the
range in tens of volts. For example, an 800V range is indicated
by "80" and 150V range is indicated by "15".
The sixth number specifies the bias
as a percentage of the range. In other words, "1" is 10% of the
range and "5" is 50% of the range. If the range needs to be
specified more precisely, then a seventh number "15" would
specify a bias that is 15% of the range. Zero bias and 100% bias
are both available. For zero percentage bias, the sixth number
is "0". For 100% bias use "00" as the sixth and seventh numbers.
Custom
Models Some applications require features beyond the scope of
standard and tailored models. These custom models are routinely
developed at Viking Industrial Products to fulfill almost any
set of requirements. Some possible custom features are:
