Selection of the Power-manufacture,factory,supplier from China

Selection and use of semiconductor laser power supplyFirst, the basic requirements of semiconductor laser power supply1. Constant current output: short-circuit constant current output, load changes or short-circuit automatic adaptation.2. Output current ripple: ripple, noise and rated output current cannot exceed the maximum current that the laser tube can bear.3. Output voltage ripple: Ripple voltage noise will not damage the laser immediately, but if serious, it will affect the life of the laser.4. Soft start: Slow start current curve, no overshoot.5.

What is the principle of pulsed strong light sterilizationPulsed strong light is the synergistic action of visible light, infrared light and ultraviolet light on microorganisms, which can destroy the cell wall and nucleic acid structure of microorganisms, thus killing microorganisms. Pulsed strong light has obvious bactericidal effect on mold, gram-positive pathogenic bacteria, Gram-negative pathogenic bacteria, aerobic bacterial spores and fungal conidia, Staphylococcus aureus, Bacillus subtilis, yeast and so on.

The basic principle of PWM switching power supplyAlthough pulse-width-modulated (PWM) switching power supplies have been around for a long time, they were not widely accepted and used until the mid-1970s. Switching power supplies have many advantages over linear power supplies.For the same power capacity, switching power supplies are more efficient and smaller than linear power supplies, but the design is more complex and electromagnetic interference (EMI) is more severe.There are two approaches to the current design of switching power supplies.

On August 26, 2022, Mr. Hiroyuki Niuda, general manager of Denso, Mr. Liu Zhiqian, Director of quality Assurance Department, Ms. Yang Xiaozhi, director of Purchasing Department, visited our company on the spot and negotiated business. Mr.

Along with the continuous development of economy in our country, most areas begin to produce electric power equipment, which makes the national grid electric power output insufficient, coupled with the aging of the power output facilities, eventually causes the voltage at the end of the circuit to be too low, which brings great influence on the stability of laser output. The stable output of laser energy is a necessary condition for laser production.

The principle of laser generationLASER is written as "Light Amplification by Stimulated Emission of Radiation", which means that by the principle of "excitation emission", the amplification of light waves is generated, which is called "laser". The motion state of electrons can be divided into different energy levels. When electrons transition from high energy level to low energy level, they will release electromagnetic waves of corresponding energy (the so-called spontaneous radiation).

Pulsed bright light sterilization, what is the status of this field?Pulsed strong light has been successfully used in air disinfection, food and beverage sterilization. Because of its sterilization speed, has a unique advantage, and will not change any ingredients of the material, does not affect the color and taste of the material.

Classification of switching power suppliesSwitching power supplies can be divided into AC/DC and DC/DC. As a secondary power supply, DC/DC converter has realized modularization, and the design technology and production process have been mature and standardized at home and abroad, and has been recognized by users. However, due to its own characteristics, the primary power AC/DC has encountered more complex technical problems and manufacturing problems in the process of modularization.

Laser engraving machine in the process of the use of skillsBefore starting work, you should carefully check the spelling of the text portion of the engraving project, and if conditions permit, print the contents and confirm with the customer. If you want to avoid the dislocation of the sculpture in the process of engraving, you need to do a good job of prevention, and implement the corresponding solution when the dislocation problem occurs.Error checking:a. Check whether the pliers or clamp used for engraving are wrongb. Whether the pliers or clips are wornc.

Laser power supply technicians are important members of the operation of laser equipment, but in the operation of laser power supply, will also encounter all kinds of difficulties, today we summarized some of the first-line manufacturers of technical personnel to provide common problems to discuss with you:▲ Power failure:Problems occur: Because the laser power supply system, especially the high-power laser power supply system requires a large amount of voltage, if the voltage is not stable, it will produce inconsistent output power, resulting in catastrophic damage.Solution: If you do not hav
