Specialty Concepts offers MARK series photovoltaic regulators/monitors and ASC charge controllers. The MARK series photovoltaic regulators are available in two models, namely MARK/15 and MARK/22. The MARK/15 solid-state charge controller is suitable for photovoltaic systems that have current rates up to 22A. It is available in 12V and 24V models. This charge controller is equipped with a LCD meter that displays array current, charge set-point, and battery voltage.
The MARK/15 photovoltaic regulator has fuse protection on array and battery. It is capable of controlling array current up to 15A or 22A. This controller has an optional external or internal temperature compensation, 10A low-voltage load-disconnect and battery condition indicator. It features pulse charging, switching shunt, field adjustable set-points, over-current protection, reverse leakage protection, reverse polarity protection, lightning protection, low power consumption and input noise suppression.
This charger controller is a 100% solid-state charge controller. It can operate in low or high temperatures. The MARK/15 accurately monitors the battery voltage of the system, calibration of the charge set-point and solar charge current. It incorporates a shunt transistor to control the current flow through a blocking diode. It turns on the system for charging when the battery charge drops and turns off when the battery is fully charged. The MARK/15 photovoltaic charge controller is UL recognized. It can be used in stationary or mobile photovoltaic energy systems.
