DC Output Bus Bars
The DC output bus bars are solid copper bars mounted inside the
charger on the internal chassis frame. The bus bars provide DC
connectivity from the backplane to the output connector(s) at the
front of the charger.
Mounted on the bars are several key components of the charger
self-protection features. In all models, a crowbar diode and high
current fuses provide protection for the charger modules in the
event that a reverse polarity battery is connected to the charger.
Fuse status is monitored by the MPC controller using voltage sense
looms attached to the bus bars either side of the fuses.

FS5, FS9
Calibrated current shunts fitted to the output circuit allow
accurate current measurement at high amperages. These
shunts are fitted with voltage sense looms monitored by the
MPC controller.
