Voltage Control
The output voltage of the rectifiers is controlled by a number of control processes. The
following diagram shows the various control processes, measured values and operating values
that determine the rectifier output voltage.
 If ac fails then any active control process stops. No control process can start until the ac supply is
restored.
Float Voltage
Configuration
Set the following parameter.
Parameter
Description
Where to find:
Float Voltage
Set to the voltage required to maintain optimum
battery charge (at the nominal ambient
temperature*) as specified by the battery
manufacturer. The bus voltage may be adjusted
above or below this value by the System Control
Processes.
 *This is the same as the Reference
Temperature used by Temperature
Compensation. See details on page 21.

 The system voltage is limited by maximum and minimum values. The values are viewable in
DCTools at Control Processes > Voltage Control. These values are not configurable.
