Specialty Concepts Mark 15 and 22 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. The ASC PLUS features a low voltage load disconnect, a waterproof battery fuse, and a linear LED display indicating battery status.

The MARK/15™ is a solid-state charge controller for use in PV systems with currents up to 15 amps. It includes a full-featured LCD meter to display battery voltage, array current and charge set-point. It is intended to flush-mount within a wall for a very distinctive appearance. General specifications include fuse protection on both battery and array and bar graph battery condition indicator. The Mark/15 is UL Recognized.

The MARK/22 is similar to the MARK/15 but is rated for 22 amps of PV current. It also has a low-power consumption LCD digital display, which can show two different system parameters -battery voltage and array current.
