Figure2-11 Work principle diagram
The MY series UPS includes rectification/PFC, inverter, charger, bypass static switch etc function
module, the input power includes mains input, bypass input, battery input, the output mode includes
inverter output, bypass output and maintenance bypass output (if equipped).
When mains normal, the rectifier starts and the charger charges the battery at the same time. When
UPS off, if bypass normal, the system turns to bypass output; when UPS on, the mains boosts by
rectification/PFC and output DC bus voltage, and then go through inverter and output pure sine-wave
AC power, the output turns to inverter output to load from bypass output (if equipped).
When mains abnormal, the battery voltage boosts by rectification/PFC and output DC bus voltage,
and then go through inverter and output pure sine-wave AC power to load. When mains recover
normal, the UPS turns to mains mode from battery mode automatically.
2.2.2 Work Mode
There are 5 work modes of the UPS: normal mains power supply mode, battery inverter mode,
bypass power supply mode, ECO power supply mode and maintenance bypass power supply mode.
The maintenance bypass power supply mode can only suitable for install the UPS series fitting with
distribution module.
Normal mains power supply mode
When mains power normal, the UPS works in mains inverter status and charge the battery at the same
time. The work mode is as shown in Figure2-12.
