Figure 2-2 Power Module variants
A number of Power Module variants are available for different supply voltages in an output
range of between 0.37 kW and 132 kW. Depending on the Power Module used, the energy
released in regenerative mode is either
● fed back to the supply system (Efficient Infeed Technology) or
● stored in the DC link and/or fed to an external braking resistor.
