The 902-200 controller comes in an outdoor enclosure with water level sensors and sensor wire. It can be operated from a 12V or 24V array. The 902-100 control must be mounted in a dry location and used with a 24V array. 1 year warranty.

The built-in "Linear Current Boosting" circuits optimize yoiur solar water pumping system by translating the current and voltage from your DC power source into a combination that is better matched to that needed by the pump. In addition to increasing your pumping system's efficiency, the 902-200 DC Pump Controller provides your pump with protection from excessive or insufficient voltage. The controller also has the ability to automate your pumping system, ensuring that the pump does not run when the well water is too low (level sensing probes are included) or the reservoir is full (float switch must be purchased separately). The optimization, protection, and automation this controller provides make it an important component in a well designed solar water pumping system.
