The SPECIALTY CONCEPTS SYSTEM (SCS) is a versatile, industrial quality charge
controller for the efficient use of photovoltaic energy and the protection of expensive
batteries.
The SCS is a series-relay battery charge controller using mercury relays, remote
temperature compensation, adjustable charging set-points, low-voltage load
disconnect, circuit breakers, and digital metering. Lights indicate "CHARGING" and
"LOAD DISCONNECT" conditions and the meter displays battery voltage, charging and
load current, and current from an external shunt.
