2x FK425 WATER PUMP LEVEL CONTROL,AUTOMATIC ON/OFF,FLOATING SWITCH, 2 LEVEL DETECT,12VDC 1000W Max 110-220VAC,UN-ASSEMBLED KIT UN-ASSEMBLED KIT (2 Pcs.) Detail: • An electronic circuit that will constantly monitor the water level in a container. • Both maximum and minimum levels are adjustable. • Power supply : 12V. • Recommended housing : FB03 • PCB dimensions : 2.5” X 1.6” We can use this board to control the level of water in tank. This board will automatic stop the water pump when water reach to level which is set by user. You can see how to apply below image. Introductory The FK4XX Series is a rich source of projects for classroom construction and are ideal demonstrations of applied sensors of several types. Most of the FK4XX series embody three of the basic elements of electronic control i.e. Input, Process and Output, in broad range of economical, easy-to-build circuits. An additional benefit of this series is that these proven, functional control units are easily adapted to industrial, security and domestic systems. Cut-connect water pump circuit, it automatically controls water pump by shutting off when the tank is full and start pump when the tank is empty. Pump can be set to start of predetermine level of water left in the tank. Technical information - Need 12VDC Power Supply. ( 100mA is enough ) - Maximum current consume 45mA - Maximum load 1000W at max 220VAC. - 2 Level detector Low and High - Comes with the schematic and diagram Circuit performances If there is no have water in the tank. TR1 and TR2 will not working at the beginning stage because the base of TR1 and TR2 have no voltage, the collector of TR1 will having high voltage. This high voltage will transfer through D1 to the base of TR3 and make TR3 and TR4 conduct current, LED displays, relay works and water pump is working. Water level will flow pass L level and cause TR1 conduct current, shorts the collector of TR1 to ground while TR3 and TR4 still work by having feedback voltage to R8 and preventing by diode D1. Water pump is continuously working till water reaches H level, TR2 conducts current to short at the base of TR2 to ground. TR3 and TR4 will stop conducting current, LED shuts down and relay does not work, so water pump is stop working too. When water in tank is reduced respectively from H to L level, TR1 will stop conducting current, the collector then has high voltage which will transfer to diode D1 to the base of TR3. All functions will be repeated as above. Circuit Assembly The assembly of components is shown in Fig. 2. For good looking and easy assembly, the shorter components should be first installed - starting with low resistant components and then the higher. An important thing is that diodes, electrolyte capacitors, and transistors shall be carefully assembled before mounting them onto their right anode/cathode of the IC board otherwise it might cause damage to the components or the circuit. Configuration of the anode and the cathode is shown in Fig 3. Use the soldering iron/gun not exceeding 40 watts and the solder of tin-lead 60:40 with flux within. Recheck the correctness of installation after soldering. In case of wrong position, just use lead absorber or lead extractor wire to avoid probable damage to the IC. Testing Giving connected 12VDC to the circuit. 1.At the beginning stage, LED displays and relay works. Connecting H pole with COM pole, LED will shut down and relay stop working. Taking H off from COM pole, LED displays and relay will work again. 2.Shorting L pole with COM, relay is working. Shorting H pole to COM again. Now, COM, L and H are connected, LED shuts down and relay stop working. Taking H pole off, relay does not work and LED does not display. Taking L pole off from COM, now LED displays while relay works. Free Shipping Handling WORLDWIDE.
