5.1 SPS-Charger board (Power Stage Board)
The PSDR board consists of SPS. It gives the whole UPS system power supply.
You can set the current from 1A to 4A by changing the jumper. And you also can choose a different
voltage corresponding to different battery pieces by changing the jumper on the CNTL board and the
Charger-Charger board. The charge voltage is controlled by CNTL board.
5.2 CNTL board (Control Board)
The CNTL board is the core of the UPS system. It controls the actions of the semiconductors and other
mechanical switches, the display of the LED/LCD, the sound of the buzzer, the communication with the
computer, and other important tasks.
5.3 Communication board
The Communication board provides RS232/USB interface to the users, and it also provide one EPO port
to cut off the output immediately.
5.4 EMI board
The EMI board can prevent the UPS from external electronic/magnetic noise generated by other
electronic systems, and also prevent other systems from the noise generated inside of the UPS system.
And the MOV is also on the EMI board which can absorb the surge to protect the UPS system.
5.5 Main Power board
The Main Power board is the most expensive and biggest PCB in the UPS. It converts the AC/DC power
to a pure sine waveform. And then it converts the DC/AC power. There are many semiconductors and
easy-failure components on the board, so it
’s required to pay more attention when UPS is abnormal.
5.6 Para(A) and Para(B) board
The Para(A) board and Para(B) board is used for parallel communication when the UPS system is
