Item Type: Water Level Controller Module <br>Material: PCB <br>Power Supply Voltage: DC 12V <br>Control Motor Power: Recommended Within 1000W1、Professional Design: Automatic liquid level sensing control module is carefully developed according to the actual needs of water pumping in home factories and mines. <br>2、Control Relay: 12V DC water level controller module is based on the detection of water level in the pool (water tower) to control the high current relay to achieve control. <br>3、Superior Performance: Water level controller module has the characteristics of small size, easy wiring, small power consumption, large switching capacity, strong anti?interference, and high functional stability. <br>4、Automatic Control: Level controller module can steadily realize the pool (water tower) is short of water automatically turn on the pump to pump water, pump to full automatically stop the pump. <br>5、Working Principle: The upper s in z under x probe leave the water relay suction closed, the upper s in z under x probe soak to the water when the relay is disconnected.1 x <br> <br>Water&nbsp;Level&nbsp;Controller&nbsp;Module Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
