Page 4: Principle Of Operation
3. Principle of Operation 3.1. The basic circuit of power supply Basic circuit of power supply This is a flyback converter topology. When the MOSFET is on, all rectifier diodes are reverse-based and all output capacitors supply currents to the load. The primary wire acts like a pure inductor and load current builds up linearly in it to a peak lp.
Page 5 Press the ON button to power up the optical coupler U1 and U2; powering up the U1 may have the power supply build and powering up the U2 may send a signal of SW-ON to the control board. After it receives the SWSTAUTS signal (high-level) the CPU will startup the UPS system.
Page 6: Inverter Circuit
PFC circuit The PFC is finished by the DSP and the process is shown in the above dashed frame. Firstly the hardware configuration sends signals that the DSP needs to the DSP to process it, and then the DSP sends a group of pulse signals to drive the IGBT on and off.
Page 7: Control Circuit
half-bridge topology is that leakage inductance spikes are easily clamped to the DC supply bus and any energy stored in the leakage inductance is returned to the input bus instead of having to be dissipated in some resistive element. The topology works as follows. Q1 and Q2 are switched on at alternate half cycles. The junction voltage of Q1 and Q2 is a high frequency rectangular waveform.

4. Function explanations for each PCB 4.1 PSDR board (POWER STAGE DRIVER) PSDR board configuration diagram 4.1.1. The power stage (PSDR) consists of DC power supply, power factor correction, booster, inverter, and output circuits. DC power supply: The input of PSDR is connected to line input and battery +/-.
Page 9: Control Board
4.2. Control board The Control Board (CNTL) consists of DSP,MR32、 sense circuit, control circuit and communication port. 4.3. PARL board The Parallel Board (PARL) is used for parallel communication when the UPS system is running in parallel mode. 4.4. Charger board（only for long backup time model） The input of the charger is connected to REC+/-.

Page 13 7.2 Notes： 1、Make sure that the UPS is disconnected from the utility power and the battery bank when repairs; 2、When the maintenance switch is in the UPS position, both the terminals on the terminal block and the internal UPS are electriferous; 3、When the maintenance switch is in the position of BPS, all of the terminals on the terminal blocks have voltages and all of the 3-phase live wires in the internal UPS have no voltages.
Page 14 Fig.1 2. After you finished the setting, you can see the following interface like Fig2. Fig.2 3. +BUS voltage regulation: Type “BUSP+(-)XX” command (XX is two digits from 00 to 19), then press the “ENTER” key, +BUS voltage will rise(drop) a little step. 4.

by using BUS tiny regulation command. (BUS voltage can be regulated about 0.5V every point by using BUS voltage tiny regulation command). 2. INV output voltage regulation: When the UPS run into the Inverter mode, measure the output voltage with the multimeter. then regulate the output voltage to 220± 0.5V by using output voltage regulation command.
Page 16 4. The difference between the ±Bus voltage absolute value keeps more than 40V for 2 minutes. Maybe the PSDR board is damaged; Mainly check that the IGBT and SCR etc power components for the PFC and the utility power SCR are well. Meanwhile check that the components on the drive circuit are well.
Page 17 When the battery voltage is more than 300V, the fault signal will be sent. It is probably the charger or PSDR board damaged. The Fault code is Firstly, check that the battery SCR（Q305）or the battery relay The battery “14”; (RY3、 RY4) on the PSDR board are well. Secondly, check that the The UPS beeps damaged components for the battery drive signals are normal.
Page 18 connected to the CN104/CN105 on the PSDR board via the power cord of the charger and then make sure that the other connections are correct; For the standard model, there is no power cord. Replace the charger board if the BUS voltage is normal.

Page 21 3. Turn off the UPS that are running. After all of the UPSs that are running transfer to the Bypass mode, disassemble the maintenance cover board of each UPS and set the maintenance switch from “UPS” to “BPS”, then cut off the input breaker on each UPS.
Page 22 Note: If the UPS is abnormal in the above regulation, please perform maintenance according to the steps of removing single UPS. Operating process of removing the Paralleled UPS: 1. If you need to remove the UPS on normal running, press the Power-off button of the UPS that is confirmed to be removed twice continuously and the UPS will cut off its output immediately;...
