Charger Output Current vs. AC Input Voltage
When the Freedom HF is charging batteries from a weak shore power
source the AC voltage may fall as the Freedom HF draws current. To reduce
the chance of the shore power voltage collapsing below the configured
transfer level the Freedom HF will reduce the charging current at low shore
power voltage according to the following graph:
20 amps
16 amps
40 amps
32 amps
90 105
volts
135
