2.1. Functions
Trinergy™ Cube incorporates the three existing standard topologies into one transformer-free UPS:
Maximum Power Control mode (IEC 62040-3 VFI):
This is the double conversion mode which provides the highest level of power conditioning. It protects
the load from all types of electrical network disturbances that would use a greater amount of energy.
Efficiency at full load with the latest transformer-free technology is over 96.5% (see Fig. 1 - on page 7).

Maximum Energy Saving mode ( IEC 62040-3 VFD):
This mode detects when there is no need for conditioning and allows energy flow to pass through the
bypass line. In this case, efficiency reaches 99.5% (see Fig. 2 - on page 7).
