3ZGR VERSATILE RT - 10 KVA OPERATION
Operation Modes
ZGR VERSATILE RT - 10 KVA is a double-conversion on-line UPS that may operate in the following alternative
modes：
3.1.1 Normal mode
The rectifier/charger derives power from the AC mains and supplies DC power to the inverter while floating and
boosting charge the battery simultaneously. Then, the inverter converts the DC power to AC and supplies to the
load (Fig. 3-1).
Fig. 3-1 Normal mode
3.1.2 Battery mode (Stored Energy Mode)
If the AC mains input power fails, the inverter, which obtains power from the battery, supplies the critical AC load.
There is no power interruption to the critical load. The UPS will automatically return to Normal Mode when AC
supply recovers (Fig. 3-2).
Fig. 3-2 Battery mode
3.1.3 Bypass mode
If the inverter is out of order, or if overload occurs, the static transfer switch will be activated to transfer the load
from the inverter supply to bypass supply without interruption to the critical load (Fig. 3-3).
In the event that the inverter output is not synchronized with the bypass AC source, the static switch will perform
a transfer of the load from the inverter to the bypass with power interruption to the critical AC load. This is to avoid
paralleling of unsynchronized AC sources. This interruption is programmable but typically set to be less than an
electrical cycle e.g. less than 15 ms (50 Hz) or less than 13,33 ms (60 Hz).
