1.2 System Features
Inverter
The inverter consists of a sine wave inverter that supplies power when AC loads are applied. Depended on
your model, the inverter develops 2100 or 3200 watts of continuous power. Using TruSine
®
technology, a
very high quality sine wave is produced. Total harmonic distortion (THD) is less than 4.0 percent. The
inverter also has a three second surge rating of 6400 Watts.
Battery Charger with Automatic Power Management
A high efficiency, multi-stage battery charger, allows fully automatic charging of flooded and gel lead acid
battery banks. The efficient 0.85PF, compared to typical 0.59PF on triac type chargers, allows full charger
output from a 30-amp AC source. The system’s Bulk, Absorption, and Float charge cycle quickly charges
and maintains the battery bank. An Equalization charge cycle is provided for flooded lead acid battery
maintenance.
Automatic Power Management (APM) monitors the AC Input current and will reduce the battery charger
output as needed to keep the AC input current below the preset APM Limit.
GenStart/Auto-Throttle
The GenStart/Auto-Throttle feature provides a start/stop signal to control an automatic throttle module. The
start/stop signal consists of a contact closure to start the Auto-Throttle based on battery voltage of 12.3 VDC.
The GenStart/Auto-Throttle turns off when the battery charging current falling below 10 amps. Call Vanner
at 1-800-ACPOWER for technical assistance in selecting the proper auto-throttle kit to use for this
application.
Low Battery Contact
This contact allows remote monitoring of the Inverters battery status. The contact will closes when battery
voltage falls below 11 volts. This will alert the user to take appropriate measures to avoid shutdown of the
Inverter at 10.5VDC.
Remote Power Switch
This loop between Options Terminal 7 and 8 (left side of Options Terminal) allow remote control of the
system On/Off. Tying these two terminals together or optionally, tying the terminal 7 (
Remote Switch)
to
battery ground applies power to the unit.
Note:
The Front Panel switch will always overrule the remote switch in terms of disabling the unit.
System Control
The ITC contains a System ON/OFF Switch located in the front of the ITC. This switch is used to turn the
control power ON and OFF. This power switch also has a break out loop for a series switch that can be
placed in a remote location from the unit (See
Remote Power Switch
above). A control microprocessor
provides a variety of protection interlocks, system fault detection/reporting/recovery, storage of system data
parameters, and high-speed data communications to the ITC Control/Display Unit. This Control/Display Unit
also has individual on/off switches for independent Inverter and Charger control. The ITC will protect itself in
the event of any overload, over temperature, high or low battery voltage condition.
ITC Control/Display Unit
The ITC Control/Display Unit is a user interface that is connected to the ITC Control Board via a 6-wire
communication bus. This Control/Display unit can be an integral part of the Inverter or can be removed and
mounted in a remote area to allowing remote system operation. Two of these units can talk to the System
Control Board one Unit would be configured as a Master, and the other as Slave. The configuration switches
on top of the Master allow programming of the Charger current, Automatic Power Management and battery
type settings.
NOTE:
It should be noted that if the Control Display unit is taken out of the front of the unit, the cover plate
