System
Protections
The ToughPower is equipped with software and hardware protections that will ensure the internal
electronics components and the connected battery remain within safety operating parameters. If the unit
enters any protection mode or detects any faults the status LED located on the front of the ToughPower
(next to the Master Switch) will pulse RED to notify this condition as detailed in section
FAULT LED
Indication
.
Under
normal
operation
the
LED
will
turn
on
GREEN.
Table below summarizes what features are enabled and available depending on the active protection
mode.

Low
Voltage
Protection
The built-in sensors monitor the Battery Voltage constantly. If during
usage the Battery Voltage drops below the pre-set limits defined for
each battery type (see table below) the ToughPower will
automatically activate the LOW VOLTAGE Protection Mode. All AC
and DC Power Outlets are automatically
disabled to isolate and
protect the battery from damage. All Charging Inputs remain
open to
accept Charging Power as soon as it becomes available. The LCD will
display
the
following
message
to
notify
this
event.

For Lead-Acid family battery types the Low Voltage limit is dynamic depending on the System Load to
compensate
for

internal
battery
losses
associated
with
these
types
of
batteries.
