8720MC-RPS Power Supply Configuration
In this example, three-phase AC input power is fed to the Bulletin 8720MC
regenerative power supply. The 8720MC-RPS DC-bus voltage supplies the
Kinetix 5700 DC-bus via the capacitor module. If the 8720MC-RPS190 is
used, the 2198-CAPMOD-DCBUS-IO extension module is required.
DC-bus full-regeneration is possible with this configuration.

(1) This M1 contactor is controlled by the 8720MC regenerative power supply.
IMPORTANT
The 8720MC-RPS power supply is not compatible with the iTRAK power
supply.
