RATINGS
ATTENTION: All “FX” inverter/chargers are ETL listed to UL 1741.
All “Mobile” FX inverter/chargers are ETL listed to UL 458.
ETL is a Nationally Recognized Testing Laboratory (NRTL).
NOMINAL SYSTEM AC VOLTAGE:
This is the AC output voltage produced by an FX system. Each FX produces 120 VAC but multiple FXs can be configured in
parallel, series or 3-phase to produce different voltages between their AC output connections.
Single Phase
120 VAC at 60 Hz (VAC = volts AC, Hz = hertz)
Series Stacked
120 VAC at 60 Hz per AC output leg / 240VAC at 60Hz between the AC output legs
Parallel Stacked
120 VAC at 60 Hz on one AC output leg
Three Phase Stacked
120 VAC at 60 Hz per AC output leg / 208 VAC at 60 Hz between AC output legs (Y-connected)
RECOMMENDED DC VOLTAGE RANGE:
This is the DC battery voltage range to be used for operating the FX. The last two digits in the model number designate the
nominal DC voltage. Example: FX2024MT – 24V DC Voltage. The recommended battery voltage range is as follows.
12V Systems
11 – 16 VDC (VDC = volts DC)
24V Systems
22 – 32 VDC
32V Systems
29 – 43 VDC
48V Systems
44 – 64 VDC
MAXIMUM DC INPUT CURRENT:
This is the maximum DC current that the FX will draw from the battery when starting very large AC loads. It is not used for
sizing the DC disconnect or selecting DC cable gauge. It is used to select the minimum reasonable battery capacity.
12V FXs
600 ADC per FX (ADC = amps DC)
24V FXs
300 ADC per FX
32V FXs
225 ADC per FX
48V FXs
150 ADC per FX
RATED DC INPUT CURRENT:
This is the maximum continuous DC current that the FX will draw from the batteries when inverting.

AC INPUT OPERATING VOLTAGE RANGE:
This is the recommended AC input voltage range to be supplied to the FX. Voltages outside of this range may damage AC
loads connected to the FXs AC output terminals. This is only a recommendation, neither the FX’s defaults nor the set point
limits.
All FXs
90 – 150 VAC (VAC = volts AC)
Defaults = 108 – 140 VAC
MAXIMUM AC INPUT CURRENT:
An AC input source connected to the FX supplies power for two separate internal AC circuits – the AC transfer switch and the
battery charger. The AC transfer switch transfers the AC input power through the FX to the AC loads connected to the AC
output of the FX. The FX’s battery charger will “back off” when the combined amperage of the AC loads and the battery
charger exceeds the “AC Input Limit” (default of 28 AAC for Mobile FXs, 48 AAC for non-Moblie FXs). This “AC Input Limit”
can be adjusted so as not to overload a generator or trip a breaker that is connected to the AC input of the FX. If your
generator cannot continuously produce the “AC Input Limit” or you are connecting to an AC input source that has a breaker
that is rated for less than the “AC Input Limit”, please refer to the ADVANCED section to change this setting.
All “Mobile” FXs
30 AAC per FX (AAC = amps AC)
All Other FXs
60 AAC per FX (AAC = amps AC)
