Sunpumps PCA series pump controllers are high quality, micro-processor contolled DC power converters designed as the interface between a DC powered pump and the power source. 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.
One of the features of a pump controller is to boost the current of solar modules in low sunlight conditions while holding the voltage of the solar modules around the maxmimum power point. This allows a pump to start earlier in the morning and stay running longer in the evening.
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.
