- Prevents circulating currents in parallel bridges -

The Bonitron M3345CBM is designed to offer system integrators a low cost solution for providing either line regeneration or dynamic braking for multiple drives.
Traditionally, integrators have provided a common DC bus for the drives and regenerated energy. This required the drives to be connected to a common bus power supply. The M3345CBM provides blocking diodes that isolate the drives from each other while still establishing a shared common DC bus which eliminates the problems encountered with older approaches.

Two applications ideal for regen sharing:

  1. Several drives, each producing a small amount of regenerated energy and sharing a line regen module large enough to handle the sum total amount of regenerated energy.
  2. Multiple drive applications which have regeneration occurring on only one drive at a time.
    Applications involving more than 200 Amps of regen should be reviewed with Bonitron engineering.
 

Common Bus Sharing Diodes
M3345CBM

Common Bus Sharing Diodes create a two-way flow of power . This allows for shared power between drives as well as shared components on the DC bus while preventing potentially damaging circulating currents between drives.

 

Features

  • One module can be configured for a wide range of ratings and VFD configurations
  • 3 - 100 Horsepower, 10 - 200 Amps DC
  • Branch fusing is included
  • Parallel modules for additional branches
  • Isolation of multiple connected drives through diodes

Advantages

  • Allows the use of one RideThru, Braking, or Regen module with multiple drives
  • Eliminates the need for common bus configuration
  • Low installation costs
  • Compatible with most variable frequency drives
  • Simple connectivity
  • Drives are individually isolated and protected

Benefits

  • Saves space and cost by using one Bonitron module with multiple drives
  • Easy retrofits for non-common bused applications with multiple drives
  • Diode isolation protects individual drives
  • Easy retrofits and initial installations
  • Allows for quick, uncomplicated installation to maximize production uptime
