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. Internal 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 banks.
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.
