System Features
Inverter
The inverter consists of a sine wave inverter that supplies power when AC loads are applied. Depending on
your model, the inverter develops 2100, 3200 or 3600 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.
Battery Charger with Automatic Power Management
The high efficiency, multi-stage battery charger allows automatic charging of flooded lead acid and gel type
batteries. The efficient 0.85 power factor or PF, compared to typical 0.59PF on triac pulse 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 available for flooded lead
acid battery maintenance. In addition, there is an optional battery temperature sensor to reduce battery
float voltage as temperature increases above 25° Celsius.
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 Contact
The GenStart feature provides a start/stop signal to control an automatic generator. The start/stop signal
consists of a contact closure to start the Gen. Start based on battery voltage of 12.3 (24.6) VDC. The
GenStart turns off when the battery charging current falling below 10 amps.
Low Battery or Fan On Contact
The Low
Battery contact allows remote monitoring of the Inverter‟s battery status. The contact will close
when battery voltage falls below 11.0 (22.0) volts. This will alert the user to take appropriate measures to
avoid shutdown of the Inverter at 10.5 (21.0) VDC. The SP00172 offers a Fan On contact instead of the
Low Battery contact for turning on an external fan or blower when the ITC‟s fan is on.
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
modular cable. 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 display 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
