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
to the AC loads. The FX’s battery charger will “back off” if the total AC loads—including the charger—
exceed the AC input current limit (default setting is 50 AAC). This “Input Limit” can be adjusted using
the MATE to avoid overloading a generator or trip a circuit breaker. If your generator cannot produce
50 AAC or you are connecting to an AC input source that has a breaker that is rated for less than
50 AAC, please refer to the FX and VFX Series Inverter/Charger Programming Manual to change this
setting.
All LA Series Inverter/Chargers 60 AAC per FX (AAC = Amps AC)
MAXIMUM CURRENT FOR BATTERY CHARGER
Due to heat restraints, the FX limits incoming AC current to recharge the battery. Please refer to the FX
and VFX Series Inverter/Charger Programming Manual to adjust this setting. The battery charger has
an efficiency of better than 80%. Other factors, such as cable losses, might reduce this efficiency.
MAXIMUM AND DEFAULT AC INPUT AND DC (bulk stage) OUTPUT VALUES
MAXIMUM AC OUTPUT CURRENT
This is the amount of surge current that the FX will quickly supply for a split second. Depending on the
size of the surge, the FX can be overloaded for a minimum time of 5 seconds to a maximum time of 30
minutes.
