8720MC-RPS Power Supply Input Power 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.
• The 8720MC-RPS065 provides 65 A of DC-bus current. The 2198-CAPMOD-2240 capacitor module and 2198-DCBUSCOND-RP312 DC-bus
conditioner are required to reduce voltage stress on the system components.
• If the 8720MC-RPS190 is used, the capacitor module and DC-bus conditioner module provide up to 208 A of DC input current. DC-bus
full-regeneration is possible with this configuration.
• The DC-bus conditioner module is required when the combined motor cable length for each cluster exceeds 400 m (1312 ft). See the
Kinetix 5700 Servo Drives User Manual, publication 2198-UM002
, for more information on the when accessory modules are required.
(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.
