UPS power is an important uninterruptible power supply in the world today, providing a stable, uninterrupted power supply to computer network systems or other power electronics. Reliability is the most important indicator for all UPS power supplies, because it can protect other power equipment, and the entire power system will not work because of UPS power problems. Each UPS power user chooses priority when considering product reliability. UPS power supply reliability is usually affected by the following factors: First, Elect...

Wind power is forming a boom in the world, and wind power does not require fuel. There is also no radiation or air pollution. Wind power converts the kinetic energy of wind into electric energy. Wind energy is a clean and pollution-free renewable energy source. It has been used very early, mainly through windmills to pump water, grind surface, etc. Now, people are interested in how to use wind to generate electricity, and what role does wind power resistor play in this process? The wind is very complicated. Wind power uses th...

The resistors have their own certain power. In many circuits, the power of the resistor must be determined and applied. Braking resistors are a very important resistor in the inverter circuit, and its power usage is also critical. If the braking resistor power is not used accurately, it will affect the efficiency of the entire inverter. Engineers often use the derating principle when using braking resistors, that is, the nominal power of the resistor will be less than the power consumed during power-on. The braking resistor w...

Alloy resistance is a resistor made of a metal alloy material, which has a strong electrical conductivity and is often used for sampling current in a circuit. Due to the particularity of the materials produced, the alloy resistance has the advantages of low resistance, high precision, low temperature coefficient, withstand current and high power. Many projects use alloy resistance when they are tested for pressure resistance. Then the resistance of alloy resistance is felt by those aspects. The withstand voltage of the alloy ...

The materials used to produce the resistors vary in performance. People looking for resistance products often confuse metal film resistance with metal oxide film resistance. Although they differ by only two words in the text, they are quite different. Today we will analyze the difference between the metal film resistance and the metal oxide film resistance. We know that the metal film resistor is made of special metal or alloy as the resistance material. It has excellent pulse overload characteristics and mechanical propertie...

The resistor has four functions, namely voltage divider, shunt, impedance matching and filtering. There are many types of resistors. We usually have fixed resistors, variable resistors, special resistors, RT-type carbon film resistors, RJ-type metal film resistors, RX-type wirewound resistors, chip resistors, high-power resistors, and low-power resistors. So how many types of resistors are used in our production? First, the resistor has a shunt function and is often used in a variety of circuits for the distribution of curren...

The smart meter industry is one of the most widely used industries for shunts, with different types of shunts on each smart meter. The shunt is usually installed in a smart meter with a screw hole design. It is precisely because of this design that the shunt has many problems to be solved in the meter. The shunt usually samples the current of the smart meter circuit. The connection between the relay shunt and the terminal is based on a screw hole with a diameter of 4 to 5 mm at the splitter and the terminal block, and then th...

Copiers are an office equipment commonly used in our lives. In many cases, copiers have problems. In fact, the thermistors have failed and cannot work properly. How to distinguish whether the copiers thermistor is burnt out, the maintenance personnel need to master some skills to identify the copiers thermistor fault and can repaire quickly. What are the identification methods and solutions for these copiers? First we have to identify if the copier thermistor is burnt out. At normal temperature, we use a multimeter to measur...
