Table 30. Electrical Input Specifications
Input Voltage Limits Nominal Input Voltage Minimum Maximum
120VAC 88VAC 144VAC
Nominal Frequency
Online: 60 Hz, Output frequency tracks input line frequency up to limit, which is adjustable from
±0.01 Hz to ±3.00 Hz. Inverter turns on if line frequency exceeds the selected limit. On inverter:
60 Hz (FX) ±0.03 Hz.
Nominal Frequency Limits Nominal Output Frequency Minimum Maximum
60Hz 57Hz 63Hz
Inrush Current Inrush current at power up < 250 amps for one cycle.
Input Current Limits FX3100 120V in / 120V Out 3.1kVA / 2.2kW 30 Amps
Input Current THD <10% at full resistive load, under normal operating conditions and with the batteries fully
charged with the charger in the off mode.
Input Power Factor Input power factor shall be the load power factor when batteries are fully charged.
TVSS Input Noise
Suppression
EN 60950 and IEC62040-1 (contained in EN60950)
IEEE C62.41
Joule Rating shall be 150 Joules per UPS chassis
Inrush Current Inrush current at power up < 250 amps for one cycle.
ABF Protection Anti Backfeed protection compliant with UL1778, 5th ED
Regulation
±3% load regulation (under any line, load, or battery condition to within -8.3% and +5% of
nominal)
Voltage Waveform Sine wave; <5% THD at rated linear loads, computer-grade power
DC Input Protection DC fuse and battery charger fuse
UPS Startup
The Eaton Ferrups FX UPS will start with no internal batteries and an AC input source.
The Eaton Ferrups FX UPS will not start with only batteries and no AC input source.
Table 31. Electrical Output Specifications
Voltage Regulation Output Voltage Regulation in battery mode operation shall be < 5%
Output voltage regulation on line shall be < 5% of nominal voltage .
Output Frequency 60Hz Only
Output Frequency
Regulation
± 3 Hz of Nominal Frequency
Output Protection The ferroresonant transformer inherently limits current and provides overload protection. The
Eaton Ferrups FX UPS has high AC and low AC output voltage alarms, as well as an overload
alarm. If the AC output voltage falls below the low AC output voltage alarm setpoint, the UPS
sounds an alarm after 5 seconds. If the AC output voltage falls below the low AC output
shutdown setpoint, the UPS sounds an alarm and shuts down. Some models have output
receptacles protected by fuses or circuit breakers.
