|
A |
Input filter and suppressers
|
Attenuate any transient disturbance pre sent in the
mains, protecting the load powered.
|
|
B |
AC-DC converter (Boost)
|
Converts the mains AC voltage to a constant DC voltage |
|
C |
Inverter |
Transforms the DC voltage provided by the Boost or the
batteries into a perfectly sinusoidal AC voltage for the load.
|
|
D |
By-pass |
Automatically switches the load to the mains in case of
an overload or UPS failure.
|
|
E |
EPO disconnecting switch
|
Completely disconnects the load from the UPS.
|
|
F |
Output filter and suppressers
|
Attenuate the transient noise generated by the UPS itself or coming from the outside, thus protecting the load being powered.
|
|
G |
Microprocessor (DSP) |
The digital heart of the machine. Decides what to do in
each situation; constantly monitors and verifies each part of the UPS.
|
|
H |
DC/DC converter and battery-charger
|
Raises the DC voltage of the batteries to a suitable value for
the inverter stage.
Recharges the batteries and maintains their charge.
|
|
I |
Battery |
The store of energy used when the mains power is down. |
