Rated voltage, the default operating voltage is the pulse width modulation (PWM) drive waveforms that frequency is f, pulsewidth is W, wherein 0
< W < 1/f, the f, the W value automatically adjusted by control unit according to the parameter and supply voltage of the solenoid valve,
The parameter of the solenoid valve is electromagnetic force, the power of the solenoid valve or the coil turn of the solenoid valve of the solenoid valve
Number；
After the solenoid valve is activated, the input voltage of the solenoid valve is adjusted to the default operating voltage.
