This electromagnetic valve energy-saving drive circuit is applicable to 12V～24V VDC as the power supply of its work, is applicable to the driving of single solenoid valve.For the solenoid valve of different model, its D.C. resistance is slightly variant, and the operating voltage needing is also different.The object maintaining in order to reach large current start, little electric current, as long as adjust the resistance of two current-limiting resistances according to the magnification factor that drives triode, circuit form is constant.That is to say, as long as drive triode model to determine, this device is applicable to all solenoid valves of voltage rating 12V～24V.
For example, two different models but voltage rating are all the solenoid valve of 12V and two different models but voltage rating is all the solenoid valve of 24V, and the D.C. resistance of their coils is respectively 8 Ω, 9 Ω and 17.5 Ω, 150 Ω.Its firing current of the solenoid valve of these four kinds of models is respectively 1.5A, 1.33A and 1.37A, 0.16A.Under the so large function of current, the power of four solenoid valves is respectively 18W, 12.7W and 32.9W, 3.8W.These four solenoid valves are connected respectively to four electromagnetic valve energy-saving drive units, then receive respectively in 12V and 24V DC electrical source.After completing startup, electromagnetic valve work is maintaining state, and now the electric current of each electromagnetic valve coil is below 50mA.Only with 50mA, calculate, now the total output of each electromagnetic valve energy-saving drive circuit is only relevant with the voltage of DC electrical source used, voltage rating is that the total output of the whole circuit of solenoid valve of 12V is 0.6W, voltage rating is that the power of the whole circuit of solenoid valve of 24V is 1.2W, and above-mentioned total output is component and solenoid valve power sum.And the actual power of four solenoid valves is respectively 0.02W, 0.023W and 0.04W, 0.38W.Therefore, carry out the driving of solenoid valve with this device, its actual power obviously reduces.If long-play, its power savings highly significant.
