Common Bus Diodes are used to tie multiple drives to a common DC bus. Bonitron offers two styles.
If drives on the AC line are connected by a DC bus, circulating currents can be created that might cause drive faults.
Sharing diodes allow a two way flow of power to and from drives, enabling them to share power between their DC
busses, while preventing circulating currents. The two-way flow allows the drives to share power with each other or
use a common braking, regen, or UPD (Uninterruptible Power for Drives) unit.
Unlike sharing diodes, isolation diodes allow only a one-way flow of power and do not allow drives to share power
with each other, completely isolating the drives and preventing circulating currents. The isolation diodes allow multiple
drives to be connected on the DC bus so that they can share one UPD. The M3460D allows
inward flow of power so that one UPD can power all of the drives connected to the DC bus.
