2.1.18. Single Input System Block for 5-10 kVA
2.1.19. Dual Input System Block (only for 5-10 kVA FM)
a)
UPS Utility Input:
To provide the AC source to the UPS rectifier circuit and charger
b)
UPS Bypass Input:
To provide the AC source to the UPS Bypass Input and Maintenance Bypass loop
c)
UPS Utility Input Breaker:
To protect the UPS Rectifier circuit from over-current
d)
UPS Bypass Input Breaker:
To protect the UPS Bypass circuit from over-current
e)
EMI Filter on UPS Utility Input:
To eliminate the magnetic interference from AC Source or UPS
Utility Input
f)
EMI Filter on UPS Bypass Input:
To eliminate the magnetic interference from AC Source or UPS
Bypass Input
g)
Fuse for UPS Utility Input:
To provide over-current protection for UPS Rectifier Circuit
h)
Rectifier and Booster:
When utility is normal, batteries will convert the AC to DC and correct input power
factor. When utility is abnormal, they will be boosted to provide the DC voltage to the Inverter
i)
Input fuse for Battery:
To protect batteries when DC-Booster is out of order
j)
Charger:
The battery charging device
k)
OVCD Relay for UPS Utility input:
To provide over-voltage protection for UPS Rectifier Circuit
l)
External Battery Bank:
To provide longer backup time by adding additional Battery bank
m)
Inverter Generator:
To convert the DC voltage to AC voltage
n)
UPS Inverter Output Fuse:
When the UPS is overloaded, the fuse will be opened
o)
Inverter Output Switch:
When the UPS is overloaded or abnormal, or the UPS is working on ECO mode or
if EPO (Emergency Power Off) is activated, the Switch will be opened
p)
Auto Bypass Loop:
When the UPS is overloaded or abnormal, the UPS will switch the UPS to bypass
output automatically from inverter output
q)
UPS Output EMI Filter:
To eliminate the magnetic interference from the UPS Output and avoid the
interference caused by the output load and the UPS
