Standard Features

Type of Power Conversion Circuit: High frequency.
3.4.2
Float Charging Output Mode: In this mode of operation, system output voltage is constant and output current does
not exceed the current limit setting. During normal operation, the battery is not required to furnish load current
and remains in a fully charged condition.
Note:
If the current demanded by the load exceeds the current limit setting of the system, the battery is
required to furnish the difference in load current and begins discharging.
Note:
If the system is used with a digital battery charge temperature compensation probe, the controller
automatically adjusts system output. This ensures proper voltage to the battery as battery ambient
temperature fluctuates.
