Pump Controllers

SunPumps PC series Pump Controllers, Sunpumps PCA and PCB series pump controllers are high quality, micro-processor based DC power converters designed as the interface between a DC powered pump and the power source. The DC source may be solar modules batteries or systems using wind generators. The main purpose of a PC series controller is to maximize the total daily water delivery while providing protection for the pump as well as the power source.

The primary function of the PC series controller is to boost the current of solar modules in low sunlight conditions while holding the voltage of the solar modules\at the maxmimum power point. This allows a pump to start earlier in the morning and stay running longer in the evening.

Another function of the PC Controller when used with the ECO pumps is that of voltage limiting. With a piston diaphragm pump it is necessary to limit the voltage in order to limit the speed of the motor. In a brushed DC motor the relationship between volts and motor revolutions is linear - if the volts a doubled then the revs are dubled also. The PC Controller will limit the voltage in the ECO systems to 30 volts.

SunPumps PC series controllers have many unique features designed specifically for water pumping. All PC series controllers include a pump speed control circuit, a remote switch circuit, a sensor-less low water cut-off circuit, an electronic circuit breaker and indicator lights. The PCB series controllers have specific models for Brushless DC as well as Brush-type DC motors..
