8720MC-RPS Regenerative Power Supply Overview
About the 8720MC-RPS
Power Supply
The 8720MC-RPS power supplies and the following accessories provide
DC-bus power to servo drive systems. 8720MC-RPS power supplies can be
configured to provide full-line regeneration, regenerative braking, DC
common-bus power, and leader/follower modes for multiple units operating in
parallel.

Description
Regenerative Power
Supply
8720MC-RPS
xxx
Sinusoidal PWM converter that can control the increase of DC-bus voltage and perform continuous power generation for
one or more servo drives in multi-axis DC common-bus configurations.
Line Reactors
8720MC-LR

Bulletin 8720MC line reactors help keep equipment running longer by absorbing many of the power line disturbances that
can shut down your power supply.
EMC Line Filters
8720MC-RFI80
This EMC line filter (required for CE) is used in full-line regeneration configurations with 8720MC-RPS065 units. The
harmonic filter and varistor can be purchased separately, but are included with 8720MC-RPS065BM-HV2 units.
8720MC-EF190-VB
This EMC line filter is used in full-line regeneration configurations with 8720MC-RPS190 units and includes an AC line filter
(required for CE), magnetic contactor, harmonic filter, and varistor.
Harmonic Filter
8720MC-HF-B2
This harmonic filter can be purchased separately, but is included with 8720MC-RPS065BM-HV2 units.
Varistor
8720MC-VA-B
This varistor can be purchased separately, but is included with 8720MC-RPS065BM-HV2 units.
