• The inverter provides regulated 120 volt AC
power at a crystal controlled frequency from a
deep cycle battery bank and is rated at:

The output is a modified sine wave and is
compatible with most appliances, tools and
other 120 VAC equipment. (Note: Certain laser
printers, breadmakers, digital clocks and
small battery chargers may not operate on
modfied sinewave.) An idle mode reduces bat-
tery power consumption when loads are re-
moved from the inverter. There is a low battery
cutout protection circuit and
momentary surge power of more than twice
the inverter rating for starting electric motors.
High efficiency insures the longest possible
battery life between charges.
• The internal transfer switch allows the
Freedom Inverter/Charger to be connected to
an external AC source and transfer the source

power through directly to the loads. When the
external AC power source is disconnected, the
transfer switch allows automatic switching
back to the inverter.
The Freedom Inverter/Charger operates
as a self-contained backup power system, just
add batteries.
• Freedom battery chargers are electronically
controlled and rated at a maximum output

They are designed to rapidly and optimally
charge wet, gel, or Absorbed Glass Mat
(AGM)** cell deep-cycle batteries. Battery
charging is automatically accomplished in 3
stages: Bulk Charge, Acceptance Charge and
Float Charge.
Using a Remote Control Panel or Link
Instrumentation, a manually engaged
Equalizing Charge cycle is possible. Simple,
automatic operation is made possible by the
microprocessor in the Freedom Inverter/
Charger. In most cases, no attention or
maintenance is required.
Electronic ProtectionElectronic Protection
Electronic ProtectionElectronic Protection
Electronic Protection
Fast-acting electronic circuits protect
the inverter from overloads and short circuits.
Other protection includes a low and high
battery voltage cutoff and automatic shutdown
if an over temperature condition occurs. When
the fault condition is corrected, the unit will
automatically reset. Example: remove
overload, charge batteries or allow to cool.
**Battery type selection is set on the front of the unit
or with an optional remote
(Remote Control Panel or
Link Instrument).
