AC to DC Crossover If AC input falls below or rises above the currently selected input range limits, the unit switches to battery. The GUPS 2400A-104 variant providing a three phase input from 159-232 VAC line to line at frequencies from 370-430 Hz is also available. Contact Elgar for details on this model.
Power Loss During Crossover None
Input
Input Voltage, AC 85 to 140 VAC or 170 to 280 VAC Single Phase
Input Current, AC 33A at 120 VAC, 17A at 240 VAC
Input Frequency, AC 45 to 450 Hz
Internal Battery Module 192 VDC, 2.5 AH. Optional external battery packs available
Battery Hold-Up Time 5 minutes for internal module with 2400 VA load, 0.8 PF @ 25°C. Adding one external battery pack increases time to a minimum of 18 minutes at full rated load. Reduced loads increase backup time.

Alarms and Signals
Alarms The audible alarm sounds for an overtemperature, loss of AC input or improper battery voltage.
Signals (1) Isolated relay contacts signal loss of AC input and impending inverter shutdown due to low battery capacity and
(2) RS 232 data communications for computer interface provides information on GUPS status, alarms and parameter values.
Indicators
AC Input A three color LED indicates the condition of the AC input voltage. The LED is green when the AC input voltage is within the normal operating limits, amber when the voltage is close to the limits of the operating range and red when the operating voltage range is exceeded.
Battery A three color LED indicates the condition of the battery. The LED is green under normal operating conditions, amber when the battery is discharging or has low capacity and red when impending inverter shutdown is approached.
Load A three color LED indicates the amount of output load.
The LED is green when the load is less than 80% of maximum output, amber when the load is within 80% to 105% and red when the load exceeds 105%, indicating that the inverter will shut down if the load is maintained.
Temperature A two color LED indicates the overtemperature condition of the GUPS.
The LED is green under normal operating conditions and red when an over- temperature occurs.
Test A two color LED indicates the results of the internal self-test. A blinking light indicates the test is in progress.
When the test is complete, the LED turns green if the GUPS passes the test and red if it fails.
Controls
Output On Switches on or off the GUPS output
Test Initiates the internal self-test
Alarm Silence Silences the audible alarm
Remote Shutdown
(GUPS 2400U only)
Switches off the UPS output and disconnects the UPS from the AC input source.
Requires external SPST contact closure
Frequency Switch
Output Frequency
(GUPS 2400U only)
Selects 50 or 60 Hz output
Configuration Terminal Block
Output Voltage
(GUPS 2400U only)
Selects 115 VAC or 230 output
