AC/DC power supply COMBIVERT R6

unregulatedthree-phasecompact

Overview
The COMBIVERT R6 is a mains-driven power supply and regeneration unit designed for industrial applications. It provides an unregulated, mains-dependent DC voltage for centralized DC supply and enables energy-optimised compensation within a system or direct regeneration of excess energy back to the mains. The R6 family reduces or replaces braking resistors by returning generated energy to the grid and can feed several drives from a shared DC bus.

Highlights (COMBIVERT R6)

• Compact, cost-effective solution for centralised supply and recovery of generated energy
• Mains-driven power supply and regeneration unit
• Suitable for DC supply of multiple drives
• High continuous overload and regeneration capability
• Compatible with harmonic filters to improve network quality and reduce reactive power
• Replaces braking resistors, lowering dissipation and fire risk
• Parallel operation of several units possible
• Can be used with inverters from third-party manufacturers
