External Power Source
For the charging cycle, each Agilent MCCD mainframe requires an external dc power source to power
the cells. The external power source connects to the power bus terminals on the back of the mainframe. It
must be rated at 24 volts and be able to source 125% of the required cell charging power. For example, to
provide the cell charging power for a 256-channel system at 5 volts, 2 amperes per channel (or 2.56 kW),
the dc power source must deliver approximately 3.2 kW to each Agilent MCCD mainframe (24 V @ 133
A).
The current rating of the power source may be reduced if the charging current is reduced accordingly. For
example, to provide a maximum output current of 1 ampere per cell in the previously described system, a
source rated at least 63 amperes may be used.
