Specialty Concepts ASC-12/16A Charge Controller

ASC-12/16A Charge Controller

The ASC photovoltaic battery charge controller is ideal for 1-4 panel systems. This rugged unit holds the record for high reliability since 1981. The ASC has a simple, low component count design that is 100% solid state and is completely sealed against harsh environments. Lightning protection and a blocking diode are
included. The ASC is UL listed and is FM approved for hazardous locations. The ASC is a negative ground, switching shunt controller available in 12 and 24 volt units up to 16 amps, and 6 volt units for 4 amps. The terminal block accepts up to 12 gauge wire.
