MARK 22-12 Charge Controller

Specialty Concepts
MARK/22 Photovoltaic Charge Controller

The MARK/22 is similar to the MARK/15™ (see below) but it 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).

The Specialty Concepts, Inc. MARK 15 is a cost effective, flush mount, battery charge controller with digital system monitoring. The MARK 15 is available for 12 or 24-volt systems with charging current up to 15 amps, and provides efficient charging while protecting the batteries from damage due to overcharging. This controller is designed for use in mobile or stationary photovoltaic energy systems, with complete system monitoring of battery voltage, solar charging current, and charge set-point calibration. Chargemode status lights, battery condition LED bar-graph, a blocking diode, battery fuse and array fuse are standard.
