Chapter 1 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.

Regenerative Power
Supply
8720MC-RPSxxx
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-LRxx
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.
24V DC Power Supply 1606-XLxxx Bulletin 1606 24V DC power supply for control circuitry, digital inputs, safety, and motor brake.
