MAXIMUM SYSTEM AC VOLTAGE:
Single phase 230 VAC at 50 Hz
Parallel stacked 230 VAC at 50 Hz per 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:
12V systems 11 – 16 VDC
24V Systems 22 – 32 VDC
48V Systems 44 – 64 VDC
MAXIMUM DC INPUT CURRENT: 12V units = 600 amps / 24 V units = 300 amps / 48V units = 150 amps
This is the most sustained current the FX will draw 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.
AC INPUT OPERATING VOLTAGE RANGE: 200-260 VAC
Voltages outside of this range may damage AC loads connected to the FX’s AC output.
MAXIMUM AC INPUT CURRENT: 30 amps at 230 VAC 50 Hz
The AC input on the FX supplies power for two separate internal AC circuits – the AC transfer switch and the battery charging
system. The battery charger will “back off” when the combined total of the AC load and the battery charger exceed the
programmed AC input current limit. The FX’s default setting for this parameter is 24 amps.
RECOMMENDED MAXIMUM AC PASS THROUGH CURRENT:
30 amps at 230 VAC 50 Hz for each FX
MAXIMUM AC CURRENT FOR AC BATTERY CHARGER:
FX “E” series: 7 amps AC at 230 VAC maximum
VFX “E” series: 10 amps AC at 230 VAC maximum
Note: Factory settings are 4 amps AC for the Export version.
OPERATING FREQUENCY RANGE:
The FX will accept an AC source within the frequency range of 45 - 55 Hz. Once the FX connects to the AC source, if the
frequency goes outside of the range 45 - 55 Hz, the FX will record a warning. If the frequency of the AC source is outside of
the range of 41-59 Hz, then the FX will drop the AC source.
NOMINAL AC OUTPUT VOLTAGE:
One FX will provide 230 VAC 50 Hz single phase
Two or more FX’s may be parallel stacked for 230 VAC 50 Hz single phase
Three FX’s can be 3-phase stacked for 230/400 VAC 50 Hz
MAXIMUM AC OUTPUT CURRENT:
35 amps Peak (for 160 milliseconds) current limit
Inverter will shut down after 5 seconds of operation in current limit
