The toggle switching power supply utilizes modern power electronics technology to control the ratio of the time that the switching transistor is turned on and off to maintain a stable output voltage.
A power supply, switching power supply is generally composed of pulse width modulation (PWM control IC and MOSFET. Switching power supply and linear power supply,
Both interest rates increase with increasing output power, but the growth rates vary. The linear power supply cost is higher than the switching power supply at a certain output power point, which is called the cost reversal point. With the development and innovation of power electronics technology, switching power supply technology is also innovating from time to time. This interest reversal point is increasingly moving to the low output power end, which provides a broad space for development of switching power supplies.
The toggle switch adopts integrated circuit technology and SMT external device technology to manufacture a new generation of photoelectric switching devices with intelligent functions such as delay, broadening, external synchronization, mutual interference resistance, high reliability, stable working area and self-diagnosis. This novel photoelectric switch is an active photoelectric detection system type electronic switch using pulse modulation. The cold light source used has infrared light, red light, green light and blue light, etc., which can be contactless and quickly and without damage. Controls the state and action of various solids, liquids, transparents, black bodies, soft bodies and smoke. The waterproof and explosion-proof switch contact type travel switch has the disadvantages of low response speed, poor precision, easy detection of damage to the object to be detected and short life, and the proximity of the transistor proximity switch is short, and the non-metallic material cannot be directly detected. However, the new photoelectric switch overcomes the above shortcomings, and has small size, multiple functions, long life, high precision, fast response, long detection distance and resistance to light.
Strong electrical and magnetic interference.
Toggle switch series, photoelectric switch can be used in various applications to prevent strong light source, photoelectric switch can generally work stably when the ambient illumination is high. However, the optical axis of the sensor should be avoided against strong light sources such as sunlight and incandescent lamps. When the angle between the optical axis of the sensor (receiver) and the strong light source cannot be changed, a visor or a light-shielded long tube can be attached around the sensor. To prevent mutual interference, the MGK series of new photoelectric switches usually have the function of automatically preventing mutual interference, so there is no need to worry about mutual interference. However, when the HGK series of on-beam infrared photoelectric switches are installed close to each other in several groups, they should prevent adjacent groups and mutual interference. The most effective way to prevent this interference is to cross the emitter and receiver, and to open the group distance when you exceed the 2 groups. Of course, it is also a good idea to use a different frequency model.
