8720MC-RPS Regenerative Power Supply Overview Chapter 1
In this full-line regeneration example, the 8720MC-RPS065 unit provides
motoring and regenerative power. The harmonic filter and varistor are available
separately, but are included with the 8720MC-RPS065BM-HV2 RPS unit. In
full-line regenerative mode the 8720MC-RPS065BM-HV2 unit provides
motoring power and regenerative power.
