Bonitron M3345D Diode Sharing Modules

Bonitron > Products > Common Bus > Diodes > M3345D

Bonitron's M3345D Diode Sharing modules are 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 regen modules. This has required that the drives be connected to a common bus power supply or else the system has been directly powered through the drive input rectifiers resulting in drive fusing and rectifier problems. The M3345D modules provide blocking diodes that isolate the drives from each other while still establishing a shared, common regen bus. This eliminates the problems encountered with the older approaches.

The diode modules are available in standard, low cost versions that include fusing, heatsinks, and diodes mounted on a backplate. High speed semiconductor fuses are included for the protection of the drives and diode modules.

Common Bus Isolation Diodes
M3345D
Common Bus Isolation Diodes only allow a one-way flow of power, completely isolating the drives from each other and preventing circulating currents, while creating a common DC bus to share components. The M3345D allows power to flow from the drives to a shared brake.

Features

One module can be configured for a wide range of ratings and VFD configurations
1.5 - 100 Horsepower, 0 - 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 Ride-Thru, braking, or regen module with multiple drives to lower costs
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 by using one Bonitron module with multiple drives
Easy retrofits for non-common bused applications with multiple drives for braking, Regen, or Ride-Thru
Diode isolation protects individual drives
Easy retrofits and initial installations
Allows for quick, uncomplicated installation to minimize production downtime
