1.2 Product description
This instruction manual describes the power supply and recovery unit KEB COMBIVERT R6-S. The COMBIVERT
R6-S has the following technical features.
As a supply unit
• converts a three-phase input voltage into DC voltage.
• supplies a single KEB frequency inverter or multiple units via DC interconnection.
• can be connected in parallel, if higher supply power is required.
• increases the stability of the DC Bus voltage in shared DC Bus applications.
As a regeneration unit
• returns the excess energy from generating operation (i.e. overhauling load) to the utility supply system.
• reduces the net energy demand.
• reduces the heat dissipation.
• is environmentally friendly.
• replaces braking resistor and braking transistor.
• is cost saving and space saving.
The COMBIVERT R6-S is generally protected against over current, ground fault and high temperature. Appropriately
dimensioned DC fuses protect the DC Bus circuit against short-circuit. The following accessories are necessary
for operation with the COMBIVERT R6-S:
• Commutation choke
• HF filter (for observance of European EMC standard)
