Interconnect Cradle
The cradle has a built-in interconnection function. The maximum number of interconnected cradles is limited, depending on the output voltage of the power supply.
Maximum 4 cradles at 100 V AC (Japan)
Maximum 5 cradles at 110-120 V AC
Maximum 10 cradles at 240 V AC
This includes the master cradle, that is connected to the alternating current (AC) grid.
