C40 Charge Controller, 40A, 12/24/48V
C Series- Small System Charge or Lighting or Load Controller
» The C Series offers three models, the C35, C40, and C60, that can handle 35,40, and 60 amps of DC current.
» Silent, pulse width modulated (PWM), high efficiency operation.
» Three-stage battery charging (bulk, absorption, and float).
» Automatic overload protection in both active and passive modes.
» PV array short circuit and reverse polarity protection.
» Durable construction.
» Backed by a two year warranty.
» Microprocessor controlled.
As a Solar Charge Controller
» When used as a solar charge controller, the C35 and C60 can control 12 or 24 array operation and the C40 can control 12 and 24 VDC array operation.
» All units offer selectable settings for NiCad, flooded lead acid, gel, or absorbed glass mat batteries.
As a DC Load Controller
» As a DC load controller, the C Series has a low voltage disconnect warning system and field adjustable set points that govern automatic low and high voltage disconnect.
» Manual reset switch for emergency low voltage operation.
As a Diversion Load Controller
» The C Series automatically directs extra power to a dedicated load such as an electric water heater and ensures batteries are never over-charged.
» Plug-in remote temperature sensor (BTS) for increased charging precision.
» Cumulative amp-hour meter (CM) that can be installed on the face of the controller, or remotely (CM/R), up to 100 feet (30 m) away.
