The SBS MARS is a reference design, which enables developers to find an easy and fast solution to
provide an application with mobile energy or to impelement an uninterruptible power supply. Also
the SBS MARS could be used as finished solution, with no further changes.
If there is no possibility to connect the SBS MARS to the SM-bus then the system is able to run in a
stand alone mode with reduced functionality, too.
The SBS MARS was designed for the purpose to cover the widest spectrum of possible applications
of mobile systems. Therefore it has a wide input voltage range of 5V to 28V. The input voltage can
be supplied with an ATX power supply as well as any other power supply. The necessary connectors
are available on the SBS Mars.
Additionally different kinds of Smart Batteries can be used. That means different battery chemistry
and cell configurations up to 10S1P (= 10 cells in series and 1 parallel) at NiMH/NiCd or up to 4S3P
at LiIon/LiPo are possible. But it must be ensured to use standard Smart Batteries, which meet the
SM-Bus standard. Because of the mechanical placement of the Smart Battery connectors it is not
possible to use Smart Batteries with a greater width than 90 mm. The usage of those would be
possible, if either the connectors are placed in another way or a Smart Battery lead is used (e. g.
