As you know,COVID-19 is still affecting mostly people in China with some outbreaks in other countries. Most people who become infected experience mild illness and recover, but it can be more severe for others.So how should we protect ourselves and do not affect others in our daily life? We suggest doing as below:
1. Wash your hands frequently, Avoid touching nose, eyes and mouth
Recently,DASION released two new type brushes for Chimney and Dryer Vent Cleaning usage.And they become Hot sale within one month.I would like to introduce them to you as below lists:
In order to prevent the thunder stroke surge to disturb the LED lighting normal work, a lightning surge protection of a constant current power supply / constant voltage power supply power is designed, which is composed of GDT, MOV and TVS, according to the characteristics of lightning surges. And the lightning surge generator is used to test the protection performance of the circuit.

May I know if you and your company representatives will be there this time?
Swin Technology Co., Ltd. expects to talk more details about our UL ETL FCC CE Rohs listed led driver/switching power supply and establish long-term business relations with your company in future. Come to visit us and we believe we will have a lot of fun here.
In DC circuit, capacitors are equivalent to circuit breakers. Capacitor is a component that can store charge, and it is also one of the most commonly used electronic components.
Recently Vishay Intertechnology, Inc, we announce the launch of a new series of thin film encapsulated SMD resistance, PFRR, which is approved by ESCC-4001/023 and achieves the failure rate of R level. PFRR resistance is the first TCR device with a tolerance of 0.05%, which is low to 10ppm/ degrees.
One, explanation
The varistor is a noun in the mainland of China which means that the resistance value varies with the voltage within a certain current and voltage range, or the resistance value of the resistance value to the voltage. The English name is "Voltage Dependent Resistor", which is abbreviated as "VDR" or "Varistor".
The resistance material of varistor is semiconductor, so it is a variety of semiconductor resistor. Now, a large number of Zinc Oxide varistors (ZnO) are mainly composed of two valence elements (Zn) and six valence element oxygen (O). Therefore, from the material point of view, Zinc Oxide varistor is a type of "II - VI oxide semiconductor". In Taiwan, China, varistors are called "surge absorber", sometimes called "electric shock (surge) suppressor (absorber)".
The self recovery fuse is a kind of over current electronic protection element. The polymer organic polymer is mixed with conductive particle material under the condition of high pressure, high temperature and vulcanization, and it is processed by special process. It's customary to call PPTC (PolyerPositiveTemperature Coefficent) self recovery fuse. Strictly speaking, PPTC is not self restoring fuse, ResettableFuse is self restoring fuse.
This year is 2018, dog year. And LHWYLED has been set up over 5 years. We are being manufacturing led cob or smd downlight always. So what is a qualified wholesale downlights factory ?
BLOOMINGTON, Ind. – US semi trailer tank orders are down 35% month-to-month and 39% year-to-year for the month of March, according to an FTR report, which is the lowest order activity since July 2013.
Beiben water trucks, also called as beiben water browser, beiben water wagons and beiben water carrier truck and beiben water transportation truck. . In many africa country, also called as north benz water truck, north benz water tanker truck.
Normally beiben water trucks can devided into catedegoies as follows:
High performance general electrolytic capacitor is to team them up with inductors to create oscillators. For something to oscillate, energy needs to move back and forth between two forms. For example, in a pendulum, energy moves between potential energy and kinetic energy. When the pendulum is at one end of its travel, its energy is all potential energy and it is ready to fall. When the pendulum is in the middle of its cycle, all of its potential energy turns into kinetic energy and the pendulum is moving as fast as it can. As the pendulum moves toward the other end of its swing, all the kinetic energy turns back into potential energy. This movement of energy between the two forms is what causes the oscillation.
Let's say you hook up a capacitor like this:
Radlal aluminum electrolytic capacitors is a device that stores an electrical charge or energy on it’s plate.These plates, a positive and a negative plate, are placed very close together with a insulator in between to prevent the plates from touching each other.In a way, a capacitor is a little like a battery. Although they work in completely different ways, metallized polypropylene film capacitor and batteries both store electrical energy. You should know that a battery has two terminals. Inside the battery, chemical reactions produce electrons on one terminal and absorb electrons at the other terminal.
A capacitor is a much simpler device, and it cannot produce new electrons -- it only stores them. You'll learn exactly what a capacitor is and how it's used in electronics.

Speaking of VGA Splitter, we may feel familiar but also strange .What familiar is, we may all know what the device is .when strange is, most of us seldom available to it .
A 20 megawatt (MW) solar photovoltaic PV project developed by the Chinese Company BXC was recently connected to the grid in Ghana. It represents the largest yet connected to the Ghanian grid, and also the largest PV installation in the African nation to date.
In the midst of a power crisis and a commitment to grow its renewable energy industry, the connection of a 20 MW solar PV plant must be music to the ears of Ghanaian energy officials. The plant is the largest PV installation in Ghana and is a signal of intent for a country that is making great efforts to increase its reliance on clean energy.
In daily life, we do recognize each other not by fingerprints, palm prints, iris, etc., but by human face . Thus, face recognition technology is the most attractive one among biometric technology , it is the most intuitive and natural , it has the following advantages:
Tesla has a goal of producing 500,000 cars per year by 2020. To that end, it will need to make a lot of batteries, which is why the company is working to complete its deep cycle power supply batteries plant called the Gigafactory.
The Gigafactory, which is located in Sparks, Nevada, is scheduled to be finished by 2020 and will produce more lithium ion batteries than all other lithium battery factories in the world combined. But its size isn't the only thing that impressive. Here's a look at some of the Gigafactory's coolest features.
