Shurflo 9325 LCB-G0 Linear Current Booster

LCB controllers are high quality DC power converters designed to interface between a DC brush type motor (solar) pump and the DC power source - solar panels or batteries etc.

Their mainfunction is to maximise the daily output of water while providing protection for the pump.
The solid state controller will protect the pump systems and give trouble-free service for many years. It will protect the pump from over-voltage and over-current conditions and will also provide current boosting in low sunshine conditions.
The model G0 gives basic protection and can also be connected to a remote switch or a float switch at the reservoir to turn the pump on and off as required.
