Figure 6.46 – Standard PowerFlex 7000L Control Power Distribution (with UPS option)
To reduce the size of UPS needed, the loads on the AC/DC converters
are separated into two distinct loads: the IGDPS boards and the
DC/DC power supply. The IGDPS load is only needed when the
drive is in the normal operating mode and running the motor. During
interruption of control and medium voltage, the IGDPS load demand
on the AC/DC will be not be required. Only the DC/DC will remain
energized for an extended period of time after loss of control power.
The DC/DC converter will power the main control boards and keeps
them fully functional.
