Solar Mounting Advantages
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.

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)".
