HCT PTD Current O/P
Voltage Control
This diagram clearly
shows the linearity of the
controllers output current
relative to an analog
linear 0-100% command
signal.
The
use of internal
c u r r e n t a n d o t h e r
inn ovat ive f ee dback
allows HCT to ensure
that the plug top driver
will
not negatively
influence any product that
it is connected to and will
allow the user to faithfully
follow the mechanical/
fluid curves expected.
The diagram below shows how the use of current feedback allows HCT to provide an automatically compensated output
current, irrespective of minor supply voltage fluctuations and coil heating effects. This allows the operator to fully use the
characteristics of the product under control with virtually no reduction in specification.
