RATINGS
NOMINAL SYSTEM AC VOLTAGE:
This is the AC output voltage produced by an FX system. Each FX produces 230 VAC (volts of AC) but multiple FXs can be configured in parallel or
Single Phase | 230 | VAC at 50 | Hz (VAC = volts AC, Hz = Hertz) |
Parallel Stacked | 230 | VAC at 50 | Hz on one AC output leg |
Three Phase | 230 | VAC at 50 | Hz per AC output leg (limit three)/400 VAC at 50 Hz between AC output legs |
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.
12V Systems | 11 | – 16 VDC (VDC = volts DC) |
24V Systems | 22 | – 32 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 FX’s | 600 ADC per FX (ADC = amps DC) |
24V FX’s | 300 ADC per FX |
48V FX’s | 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.
FX2012E | 190 ADC (ADC = amps DC) | |
FX2024E | 95 | ADC |
FX2348E | 55 | ADC |
VFX2612E | 250 ADC | |
VFX3024E | 145 ADC | |
VFX3048E | 70 | ADC |
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 FX’s AC output terminals.
All “Export” FX’s | 200 - 260 VAC (VAC = volts AC) |
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 charging system. 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 programmed AC input current limit (default of 24 AAC). This “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 produce 24 AAC or you are connecting to an AC input source that has a breaker that is rated for less than 30 AAC, please refer to the programming section to change this setting.
All “Export” FXs | 30 AAC per FX (AAC = amps AC) |
MAXIMUM CURRENT FOR BATTERY CHARGER:
The FX uses AC current from the AC input source to charge the battery. Due to heat constraints, the FX limits this amount of current. The maximum and default values for this setting are shown below. Please refer to the programming section to adjust this setting. The battery charger has an efficiency of 90%. There are other factors like cable losses that may reduce this efficiency. The maximum DC current that can be produced is also shown below. These maximum DC currents can only be attained in the “Bulk” charging stage.
FX2012ET | AC Max = 6 | AAC (Default = 5 AAC) | DC Max = 100 ADC | |
FX2024ET | AC Max = 7 | AAC (Default = 6 AAC) | DC Max = 55 | ADC |
FX2348ET | AC Max = 7 | AAC (Default = 6 AAC) | DC Max = 35 | ADC |
VFX2612E | AC Max = 8 | AAC (Default = 7 AAC) | DC Max = 125 ADC | |
VFX3024E | AC Max = 10 AAC (Default = 9 AAC) | DC Max = 85 | ADC |
VFX3048E | AC Max = 10 AAC (Default = 9 AAC) | DC Max = 45 | ADC |
