A supply chain is a network of retailers (retailer), distributors (dealer), and suppliers (supplier)--everyone involved in moving a produ CT from supplier to customer.Starting from one root supplier, everyone on the chain buys products from one's supplier in a price P and sell or Distribu Te them in a price, is r% higher than P. It is assumed this member in the supply chain have exactly one supplier except

are used to filter out low-frequency signals in the current. However, even low-frequency signals have frequencies of several orders of magnitude. Therefore, in order to be suitable for use at different frequencies, electrolytic capacitors are also divided into high-frequency capacitors and low-frequency capacitors (the High Frequency here is relative). The low-frequency filter capacitor is mainly used for filtering mains filtering or transformer rectification. Its working frequency is the same

(1) twists and turns Transformer Phase Shifting technology, inverter rectification side through twists and turns Transformer Phase Shifting and achieve 30 pulse rectification, from the theory of less than 29 harmonic current can be eliminated, the harmonic suppression capability of the variable frequency power supply is greatly enhanced. Because the rectifier bridge uses a two-level Tube for uncontrolled rectification, the input voltage under any load

YK-JJW (JSW) Series Product OverviewYK-JJW Series single-phase precision AC power supply, using the International Advanced Sine Energy Distribution program Power Regulation technology, represents the latest development level of AC voltage regulator technology. The circuit consists of sinusoidal energy distribution and high-power filter. It has the advantages of high overload capacity, good reliability, strong anti-jamming ability, high efficiency, lon

Some external factors can cause the switch to not work properly, such as external power supply instability, power line problems and so on. It will also cause damage to the internal parts of the switch due to power problems. If the power led on the switch is green, everything is OK and if the LEDs are off, the switch is not powered properly. In order to avoid the switch power problem, first of all to ensure the power

. A tentative strategic interpretation of the success of Ctrip: 　　first, "Supply chain" system capacity is the key to success Ctrip station like Sina, Sohu and other network portals integrated traditional media news products and resources, through the intermediary market (marketplace) to connect suppliers and consumers. As a unique resource integrator, Ctrip one palm control the country nearly hundreds of thousands of member customers, the other hand,

Wind energy, solar energy, and other alternative energy sources receive a good return on investment. If the data center manager has a golden rule, it is: Do not toss your power supply.For almost all data centers, their power supply is AC. AC is not only suitable for a single PC in the study, but also for data centers with a large number of servers. The US Environment Protection Agency predicts that the energy demand for data centers will double in t
