The "LCB - G" pump controller is a high quality DC power converter designed as an interface between a DC (Solar)-Pump (e.g. SHURflo 9300) and a DC power source, like solar panels, wind generators, batteries etc.. The main function of this controller is to maximize the daily water output while providing protection for the pump. The controller can be used in 12V and 24V systems. The solid state controller will protect the pump system and give trouble free service for many years. When used in a solar pumping system, directly connected to the solar power, it will protect the pump from over.
