a. Utility Input: AC source to the UPS.
c. Utility Input Breaker: No-fuse Breaker (NFB) for UPS input over-current protection.
e. Input EMI Filter: Protects against electromagnetic interference from the utility input.
g. Input Fuse: Over-current protection for rectifier circuit.
h. Rectifier and DC Boost: The rectifier converts AC to DC and corrects input power factor.
When utility power is abnormal, the DC boost will increase the DC voltage to acceptable level
for the inverter.
i. Battery Fuse: Over-current protection for the batteries.
j. Charger: Two-stage, constant current / constant voltage charger for batteries.
k. External Battery: When utility power is abnormal, the internal batteries provide backup power.
l. External Battery Bank: To provide extended backup time by adding additional battery bank.
External chargers can also be added.
m. Inverter: Neutral Point Clamped (NPC) type inverter converts DC to AC.
n. Inverter Output Fuse: Over-current protection for the UPS inverter output.
p. Auto Bypass Loop: When the UPS is overloaded or abnormal, the UPS will automatically
switch the load to bypass power.
q. Output EMI Filter: Eliminates magnetic interference from the UPS output and protects from
interference caused by the load.
