FAST Technologies Best Battery Diodes for Electrical Switchgear and Engine
Starting have been developed in partnership with industry leaders. Designed
to deliver power from two different batteries to one or two loads.
Two FAST BBD models are available offering 1800 amp and
4900 amp inrush current ratings, suitable for a wide range
of loads such as Engine Cranking, Switchgear Tripping
and Communications and suitable for Voltages from 12 to
150VDC nominal.

batteries to one or multiple loads.
If one battery has failed, or has a lower SOC, power will
automatically flow to the starters or loads from the other

FAST Technologies BBDS use the Solid-State technology in
high power diodes mounted on large heat sinks to reduce any
maintenance, as no forced is required.

they will operate without the need for human intervention.
As standard - FAST BBD’s include thermostatic over
temperature switches, incorporated into the heat sinks to
allow remote monitoring and indication of the heat sinks
reaching 50DegC and 110DegC.
