Introduction
The 8720MC-RPS Regenerative Power Supply Bidirectional
Converter is a sinusoidal PWM converter which can control
increase of DC bus voltage and perform continuous power
generation.
The 8720MC-RPS Regenerative Power Supply, therefore, can be
used as power supply unit for various drives and inverter units.
This instruction manual covers the 8720MC-RPS Regenerative
Power Supply for 380-460 VAC, and describes the hardware
and the start-up and programming procedure for the 8720MC-RPS
Regenerative Power Supply. Read and understand this manual
before proceeding.
All the following units are UL/C-UL listed:
8720MC-RPS027BM,
8720MC-RPS065BM and 8720MC-RPS065BS,
8720MC-RPS190BM and 8720MC-RPS190BS
Also, the Declaration of Conformity with the requirement for CE
Mark was already issued for all the units.
The 8720MC-RPS Regenerative Power Supply is a bidirectional
converter with the following features:
• Use of chopper type voltage increasing method with sinusoidal
pulse-width-modulated (PWM) waveform control.
• Programmable DC bus voltage.
• Continuous power regeneration.
• Attenuation of the higher order harmonics in the line current.
• Safety interlocks and protection.
This manual describes the details of the 8720MC-RPS Regenerative
Power Supply in order to provide the user with a complete
understanding of the installation, wiring, operation and adjustment
of the product. As an aid in finding information in this manual,
