CD4069 is a six-inverter integrated circuit. The QM-10N is a gas sensing sensor that detects gas leaks. The resistor R2, the capacitor Cl and the Zener diode DW form a simple voltage regulator circuit to provide a stable 6V operating voltage for the gas sensor. The non-gates F5 and F6 together with the resistor R5 and the capacitor C3 form an audio oscillator, which controls the on/off of the switching transistor, thereby driving the piezoelectric ceramic sheet HTD to sound. Biogas leak alarm circuit composed of CD4069:
High-power electronic power devices are repotted into an integrated module according to a certain combination of functions.
A power semiconductor module is a combination of certain functions and modes, and a power semiconductor module is a high-power electronic power device that is re-potted into a whole according to a certain function combination. Power semiconductor modules can achieve different functions according to the different components in the package. Power semiconductor modules can be used as air-cooled modules with air-cooled heat dissipation, and water-cooled modules with water-cooled heat dissipation.
It is characterized by simple installation, convenient use and maintenance, small size and light weight.
Typical applications in AC/DC motor control, various rectifier power supplies, industrial heating control, dimming, non-contact switches, electric welding machines, motor soft start, reactive power compensation, frequency converters, UPS power supplies, battery charging and discharging, etc.
