GENERAL DESCRIPTION
The Specialty Concepts Mark III/10 (SC3/10) is a battery charge controller and system
monitoring unit designed for use in mobile or stationary photovoltaic (PV) energy systems.
Lights are included to indicate system status and a front panel fuse provides over-current
protection. The SC3/10 is available for 12 volt systems with charging current up to 10 amps.
This unit uses a solid state pulse type charge controller to safely reach and maintain a full
state of charge for the battery. A blocking diode is provided to eliminate losses through the
solar panels (array) at night. LED lights indicate "Solar Charging", "Battery Up", and "Low
Battery". The fuse provides over-current and reverse polarity protection. This model is
available for 12 volt systems with charging currents up to 10 amps. The SC3/10 can be
mounted flush in the wall or on a standard, double gang electrical switch box.
