HF 1800) continuous power. The wattage rating applies to resistive
loads such as incandescent lights.
Input Voltage
The allowable Freedom HF input voltage ranges are shown in the
following table for all models except Freedom HF 1500 and

Operating
Condition
Voltage Range Comment
Full Operating
Range
Low:
10.5–15.5 volts
High:
11.8–15.5 volts
Low refers to low limit of the low voltage
threshold.
High refers to high limit of the low voltage
threshold.
Optimum
Performance
12.0–13.0 volts
Low Voltage
Alarm
Low: <11.0 volts
High: <12.3 volts
The low battery alarm beeps once every two
seconds and the display shows fault code .
Low Voltage
Shutdown
Low: <10.5 volts
High: <11.8 volts
The low battery alarm beeps every second and the
display shows fault code . The status LED
turns red and the display screen is turned OFF
within 30 seconds to protect the battery from being
over-discharged.
High Voltage
Shutdown
15.5 volts or more The over-voltage alarm beeps every second and
the display shows fault code alternating with
the battery voltage. The status LED turns red and
the display screen is turned OFF within 30 seconds
to protect itself from excessive input voltage.
NOTE: Although the Freedom HF incorporates
over-voltage protection, it can still be damaged if
input voltage exceeds 16 volts.
