LED faces the opportunity of upgrading and upgrading, and the fuse industry will take another leap forward.air conditioner fuse block pull-out

　　　　At present, LED products face the problem of relatively high costs. In terms of low-power lighting equipment, they cannot compete with rare earth energy-saving lamps, fluorescent lamps, and high-power high-pressure sodium lamps and halogen lamps.　　LED electroluminescence has high efficiency, but at the same time, it generates a lot of heat, which leads to LED light decay and ultimately shortens its working life. Moreover, LED lighting equipment faces the ceiling in terms of technology. Due to its low power of individual light-emitting components, it is necessary to combine them into relatively high power for practical use, which is a challenge.　　In order to dissipate heat, the engineering community has adopted various current heat dissipation technologies, including the most common metal fin heat sink, forced exhaust, heat pump refrigeration, heat pipe, phase change, and other heat dissipation and cooling technologies. This has led to LED lighting products with large volume, weight

Application of Self Recovery Fuses in the Protection of Rolling Gate Motors.slow blow fuse vs fast blow fuse

　　　　Rolling gate is a widely used door in modern factories and shops, which can not only automatically lift and manually switch, but also be remotely operated. The core of this type of door is to control the forward and reverse rotation of the small motor to achieve its function.　　The rolling gate is driven by a small motor, which not only often gets stuck and cannot move, but also causes the small motor to stall, overload, and burn out due to unstable voltage, high temperature, high humidity, and other reasons. So small motors must be designed with protective circuits to ensure their reliability and stability.　　There are various methods for protecting small motors. Previously, bimetallic temperature controllers were often used for protection. When the coil temperature of the small motor increased, the circuit would be disconnected, and when the temperature decreased, the circuit would be reconnected. If the power supply was not cut off, the motor would continue to be powered on and wo

Specifications and parameters of 2.5A 6V plug-in fuse.blade knife fuse fuse

　　　　Insert type fuses can be divided into A6, A16, A30, A60, A72, A240, A250, and A600 according to voltage. Their maximum voltages are 6V, 16V, 30V, 60V, 72V, 240V, 250V, and 600V, respectively. The corresponding model of the 2.5A 6V plug-in fuse is A6-250. This model is a fast fusing recoverable fuse. The maximum current of this part number is 40A, the maintenance current is 2.5A, the operating current is 5.0A, and the power generated during operation is 1.2W. The minimum internal resistance is 0.022 Ω, and the maximum internal resistance is 0.08 Ω. The operating range of plug-in fuses in this series is -40 ℃~+85 ℃. The A6-250 plug-in fuse has a square curved foot shape, with a maximum width of 11.4mm, a maximum height of 18.3mm, a foot pitch of 5.1 ± 0.5mm, a minimum foot length of 7.6mm, and a maximum thickness of 3.0mm. There are two packaging methods for A6-250 plug-in fuses: one is ribbon packaging, with a quantity of 3000 pieces per ribbon, and the other is bag packaging, with

supercheap auto blade fuse holder.How does a fuse work?

　　　　We all know that when current flows through a conductor, it will generate heat due to the presence of a certain resistance in the conductor. And the calorific value follows this formula: Q=0.24I2RT; Where Q is the heat generated, 0.24 is a constant, I is the current flowing through the conductor, R is the resistance of the conductor, and T is the time for the current to flow through the conductor; Based on this formula, we can easily see the simple working principle of a fuse.　　When the material and shape of the fuse are determined, its resistance R is relatively determined (without considering its resistance temperature coefficient). When an electric current flows through it, it generates heat, and as time increases, its heat also increases. The magnitude of current and resistance determines the rate of heat generation, while the construction and installation of a fuse determine the rate of heat dissipation. If the rate of heat generation is less than the rate of heat dissipation,

What is the function of patch self recovery fuses.battery distribution fuse block

　　　　For some industry newcomers, they may not know the definition and function of patch fuses. Patch self recovery fuses are used to protect electronic devices from damage in the event of circuit abnormalities, greatly reducing damage. A common fuse is a fusible fuse inside a light bulb, so what is a patch self recovery fuse? According to the literal meaning, it can automatically restore to a normal state. What is the function of a patch self recovery fuse? SMD self recovery fuse is a type of overcurrent electronic protection component, which is made of polymer organic polymers under high pressure, high temperature, and vulcanization reaction conditions, and is processed by a special process after adding conductive particle materials. SMD self recovery fuse is a positive temperature coefficient polymer thermistor that can replace current fuses.　　The temperature during normal operation of the patch self recovery fuse is relatively low, achieving balance. When in a low resistance state,
