2. 3 Operating Principle
1.
Input filter
: it filters the input and provides clean AC power to the UPS.
2.
AC/DC converter
: In Normal mode, it converts the AC input power to regulated DC power, and raises
the regulated DC voltage for DC/AC converter.
3.
DC/DC converter
: Raises the DC Voltage from the battery system to the optimum operating voltage for the
inverter when the UPS operates in Battery mode.
4.
DC/AC inverter
: In Normal mode, it utilizes the DC output of the AC/DC converter and inverts it into
precise, regulated sine wave AC power. In Battery mode, it receives energy from the battery through the
DC/DC converter.
5.
Bypass
: It is very important in the UPS system. In the event of a UPS fault that will not lead to UPS
shutdown, the load will be automatically transferred to the bypass. Meanwhile, the LED indicators will
indicate the fault type, and the fault information will be reported through the communication ports.
6.
Charger
: The charger of standard UPS provides 1A charging current; and long backup time provided 1K is
6.5A and 2K/3K is 5.5A charging current.
7.
Battery
: Sealed maintenance-free lead –acid battery can be used as the DC source of the UPS.
8.
Output filter
: It filters the output and provides clean AC power to the load.
