ON BATTERY operation
Figure 2.3 ON-BATTERY operation
• The battery is discharging through the DC/DC boost converter which presents the inverter with a controlled input
voltage as the battery discharges.
• The Inverter is converting the DC/DC boost converter output back into AC suitable for the load.
• The static switch is connecting the inverter output to the UPS output terminals.
• The load will continue to receive its regulated power until the battery discharges to its low voltage cut-out level.
ON BYPASS operation
Figure 2.4 ON-BYPASS operation
• The battery is being permanently charged by the battery charger as long as the battery charger is still serviceable
and able to operate. If the load has transferred to bypass due to an internal malfunction the battery charger may
have shut down.
• The AC/DC converter, DC/DC boost converter and inverter are all inoperative.
• The static switch is connecting the bypass line to the UPS output terminals.
Note: When operating in this mode the load is unprotected from utility power disturbances.
