Output Voltage Adjustment
Guidelines If the output voltage of the converter is not at the desired level, it can be
adjusted using the trim potentiometer on the converter front panel.
Voltage should be monitored using a portable DVM at the points shown
in Figure 6-1.
Note
It is important that adjustment of the output voltage be done slowly to
allow the voltage on the battery string to keep up with the converter
adjustment, since rapid changes can cause the converter to current
limit. When the converter is in current limit the output voltage does
not track the set point voltage.
Once the voltage has stabilized at the required level the DVM can be
removed and equalization can be completed.
