AC Transfer Specifications
NOTE: All transfer specifications are at nominal conditions: ambient temperature
of 77 °F (25 °C), split-phase 120/240 VAC, 60 Hz input, unless otherwise
specified.
With a battery temperature
sensor (provided)
The temperature compensation coefficients on a
24-volt battery
are as follows:
Flooded: 54 mV × (25 °C – BTS °C)
Gel: 54 mV × (25 °C – BTS °C)
AGM: 42 mV × (25 °C – BTS °C)
The temperature compensation coefficients on a
48-volt battery
are as follows:
Flooded: 108 mV × (25 °C – BTS °C)
Gel: 54 mV × (25 °C – BTS °C)
AGM: 42 mV × (25 °C – BTS °C)
a.Charging current derates up to 5% between 35 to 60 °C.
b.Recharging does not occur when battery voltage is below 12 V.
