In the "DB+DSB" configuration the battery is distributed, that is each power module is
provided with its own battery and battery static switch, which are independent from the others.
The isolators BCBx, located in the distribution colums at the sides of the I/O module, directly
connects the DC bus of each module to its battery.
The bypass static switch is distributed, therefore it is provided in each power module. The
pus-buttons SBCBx, which allows the operation of the back-feed contactor and the supply of the
power modules bypass line, are installed in the distribution columns.

DHE (Double High Efficiency)

VHE (Very High Efficiency), Line Interactive

ECO

UHE (Ultra High Efficiency)
3.3.1 DHE mode – Double High Efficiency
The DHE mode is basically the on-line double-conversion operation (VFI – Voltage
Frequency Independent), where the Green Conversion algorithm, which allows the losses
reduction and the consequent system efficiency increase, is active.
