70m Head 1.5m3/H Flow Solar Water Pumping System 3.8A Output Current

                                            70m Head 1.5m3/h Flow DC Solar Pump With Controller For Irrigation More Protection

 
Protection features

Electronic monitoring gives the controller the capability to monitor the system and automatically shut down in the event of:

1. Dry well conditions-- with low level switch

2. Bound pump-- with auto-reversing torque

3. High voltage surge

4. Low input voltage

5. Open motor circuit

6. Short circuit

7. Over heat

This controller provides motor overload protection by preventing motor current from exceeding rating current and by limiting the duty cycle in the event of low water level. This controller does not provide over temperature sensing of the motor.
