4.0 Limitations of Throughput

The ME-SBC can allow charge currents from either battery to fl ow through
TM
to the other battery (i.e. Main Battery to Auxiliary Battery or Auxiliary
Battery to the Main Battery). When the MOSFET turns on inside the ME-
SBC and the batteries are combined and a signifi cant inrush of current
TM
occurs. This inrush may cause the ME-SBC
reduce how much current it actually lets through to the other battery. If the
ME-SBC shutsdown to protect itself, it will restart in 10 Seconds and at-
TM
tempt to recombine. If the ME-SBC
a stable output, it will return to full output as soon as the average amperage
through the MOSFET lowers to a safe sustainable level.
note 1: When the ME-SBC
about 1/2 of the available amperage. It will continue to operate like this until
the total available Amps safely drops to a level the ME-SBC
tinuously. With a current probe, it may look like 50% of the rated output.
