introduction：HUROQuick fuse action HUROA quick fuse is a kind of fuse，Fast fuses are mainly used for short-circuit protection of semiconductor rectifier elements or rectifier devices。The overload capacity of semiconductor components is very low。It can only withstand a large overload current for a very short time，Therefore, the short-circuit protection is required to have the ability to fuse quickly。

introduction：Dc motor governor。Pulse width modulation：Pulse WidthModulator、For shortPWM、The DC motor governor is the device that regulates the speed of the DC motor， Because the DC motor has the characteristics of low speed and high torque，It can not be replaced by AC motor， Thus regulating the speed of the DC motor equipment—Dc governor，Because of its special properties、It is often used in DC load circuits、Lighting dimming or DC motor speed regulation、HW-1020v-governor、Using pulse width modulation(PWM)Principle of the production of motor governor、PWMThe governor is already here：Industrial DC motor speed regulation、Industrial conveyor belt speed regulation、Lighting mediation、Computer power cooling、Dc fan, etc、Be widely used。 Working principle： HW-A-1020type(DC12v24vVoltage universal)governor、Working principle:By changing the duty cycle of the outgoing square wave, the average current power on the load is changed from0-100%change、Thereby changing the load、Light intensity/Motor speed。Using pulse width modulation(PWM)wa

introduction：Bonner switching power supply is used to control the switch tube through the circuit for high-speed channel pass and cut-off．The direct current is converted into high frequency alternating current which is supplied to the transformer for voltage change，Thus, one or more sets of voltages are generated as required！The reason for switching to Huawei high frequency AC is that the efficiency of high frequency AC in transformer transformer circuit is higher50HzMuch taller．So switching transformers can be made very small，And its not very hot at work！Very low cost．If not50HzTheres no point in switching power to high frequencies。

introduction：Photoelectric sensorIt is a sensor using a photoelectric element as a detection element。It first converts the measured change into a change in the light signal，The light signal is then further converted into an electrical signal with the help of a photoelectric element。Photoelectric sensors generally consist of light sources、The optical path and the photoelectric element are composed of three parts。 Photoelectric sensor generally consists of processing path and processing element2 Partial composition。Its basic principle is based on the photoelectric effect，The measured change is converted into a change in the optical signal，The non-electrical signal is then further converted into an electrical signal with the help of a photoelectric element。The photoelectric effect is when light shines on an object，You can think of it as a stream of photons with a certain energy bombarding this object，The photon energy is then transferred to the electron，And all the energy of a photon is absorbed by an electron at once，W
