Analog Control Input
An input that allows the REGUL8OR to be controlled remotely with an analog
signal is provided on the rear panel on an isolated BNC connector. This input is labelled
as “
AN. INPUT”
and it accepts signals ranging from -10 V to +10 V.
This isolated input acts as an input for a digital closed-loop amplifier and it
generates a control output signal (for the external unit) which is proportional to the input
signal.
This means that the REGUL8OR will regulate the output at -100 % for a –10 V
analog input voltage, a 0% for a 0 V analog input voltage and a +100 % for a +10 V
analog input voltage.
An example of the relation between the analog input signal and the output (can
be either current or voltage, depending on the Regulation mode) is shown in
Figure 7
.
In order to avoid drifts, offset and external noise pick-up it is always suggested
to use the digital interface – e.g. Ethernet – to control the external power unit in order
to get the best performance.
