DC VOLTAGE INPUT
NOTE: The DC Voltage Input is designed for automatic voltage matching or kvar sharing.
For manual adjustment, use the External Potentiometer input instead.
NOTE: Where both (External Potentiometer and DC Voltage Input) are used
simultaneously, both inputs are summed to determine the output voltage.
Connect an external DC voltage to the input terminals. The source must be electrically isolated from
all other potentials.
Check the ‘Enable’ check box and enter
the desired control range of the pot.
For example with settings of
Offset
at
5 V and Range (% of set point / V) of
2% / V, this means at 5 V the generator
runs at nominal (230 V) and is adjustable
by +10% (+5V from
Offset
) and -30%
(-15 V from
Offset).
This results in an
adjustable range from 161 V to 253 V
(230 V -30% to +10%).
An open circuit input is treated as a 0 V input and so reduces the output voltage to the appropriate
percentage of the set point. Using the above example, an open circuit input would reduce the output
voltage to 207 V.
