7.3.3 Voltage Droop
, Single or Master Converters
Upon Shore Alarm, the Voltage Droop feature may be used to save up to 10% converter capacity
by reducing the converter output voltage up to 5%. This is offered as a solution where the yacht
does not already have power management and load-shed capabilities that can be triggered with
the Shore Cord Alarm signal. A recovery time is provided so that the system does not alarm and
droop in an oscillatory manner as the load level moves above and below the alarm threshold. 30
minutes is the default setting and can be adjusted as appropriate to the yacht’s conditions. This
recovery time is the time the droop will remain in place, regardless of alarm or load level, until
returning to the nominal converter output voltage. Voltage Droop will take precedence over
Programmable Output Voltage settings if used.
