Operating Limits

Power Output

The Freedom HW can deliver up to 1000 watts continuous power. The

wattage rating applies to resistive loads such as incandescent lights.

Input Voltage

The allowable Freedom HW input voltage ranges are shown in the

following table:

Operating
Condition Voltage Range Comment
Normal 11–15.0 V
Optimum
Performance 12.0–13.0 V
Low Voltage Alarm
“SDL” low setting
“SDH” high setting
11.0V or less
12.3 V or less
The low battery alarm beeps once
every two seconds and the display
shows fault code E05.
Low Voltage
Shutdown
“SDL” low setting
“SDH” high setting 10.5 V or less
11.8V or less
The low battery alarm beeps every
second and the display shows fault
code E01. 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
“SDL” low setting
“SDH” high setting
15.5 V or more
12.6 V or m ore
The over-voltage alarm beeps every
second and the display shows fault
code E02 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 HW
incorporates over-voltage protection,
it can still be damaged if input
voltage exceeds 16 V.
