2. 3. 2 Operation Modes
Normal mode
The UPS rectifier is supplied with AC power by the mains, and the inverter is supplied with DC power by the
rectifier, which provides continuous and uninterrupted AC power for the load. Meanwhile, the rectifier supplies a
uniform charging current or floating charging voltage to the battery. The schematic diagram of normal mode is
shown in Fig. 2-2.
Fig. 2-2 Schematic diagram of normal mode

User Manual 200 kVA-1200 kVA UPS 2 Product Overview

Bypass mode
In the inverter power supply mode, if the inverter fails, after the overload time of the inverter or the bypass is
manually switched, the static switch will switch the power supply of the load from the inverter power supply to
the static bypass power supply without interruption of the power supply of the load. The operating principle of the
bypass mode is shown in Fig. 2-3.
Fig. 2-3 Schematic diagram of bypass mode
Battery mode
The battery mode refers to the operation mode where the battery provides backup power to the load through the
inverter. When the mains power fails, the system automatically operates in the battery mode, and the battery DC
voltage is converted into pure and stable sinusoidal AC power supply for the load by the inverter. After the mains
power supply is restored, the system will automatically switch back to the normal mode without any manual
intervention, and interruption of the power supply for the load. If the mains is not restored after the battery backup
time, the system will automatically switch to bypass mode without interruption.
The operating principle of the battery mode is shown in Fig. 2-4.
Fig. 2-4 Schematic diagram of battery mode
Maintenance bypass mode
The maintenance bypass mode refers to the mode in which the power is supplied to the load through the
maintenance switch. If it is required to maintain or repair UPS after disconnection of the power supply, the
maintenance mode may be used according to the operation steps. When UPS is working in the maintenance

bypass mode, the UPS can be completely powered down, and the PCBA board and dual-conversion power devices
are not live. The operating principle of maintenance bypass mode is shown in Fig. 2-5.
Fig. 2-5 Schematic diagram of maintenance bypass mode
ECO mode
ECO mode is the economic operation mode of UPS, which can be set through LCD interface. In ECO mode, when
the bypass range is within the working range of ECO, the power is supplied for the load by the bypass and the
inverter is in standby state. When the bypass range exceeds the ECO working range, the power supply will be
switched for the load from bypass power supply to inverter power supply. ECO mode has higher system efficiency.
The operating principle of ECO mode is shown in Fig. 2-6.
Fig. 2-6 Schematic diagram of ECO mode
Mains-battery combination mode
When UPS is in normal operation, the load power exceeds the supply capacity of the mains for a short time, and
the battery will invert with the mains to supply the load.
