3.5 Standard Features
3.5.1 Type of Power Conversion Circuit: High frequency.
3.5.2 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.
