CHARGE CONTROLLERS



The Automatic Sequencing Charger™ (ASC) is a very compact, efficient 100% solid-state battery charger regulator for use in PV systems. The ASC is a negative-ground switching shunt regulator, housed in an anodized aluminum chassis and encapsulated in a hard epoxy resin. The terminal block accepts up to 10-gauge wire or a space connector, providing simple installation. The ASC is FM approved for hazardous locations, UL listed, and provides lightning and reverse leakage protection.
