Detailed Product Description: | The company's main business: the main agent wholesale Schneider switch, circuit breaker Schneider, Foshan Lighting, Siemens switches, Emmett ceiling fan, Hyderabad Man doorbell, Merlin Gerin switch, Merlin Gerin circuit breakers, Zhengdan inserted, inserted fine arts laborers into place, new home switches, wire and cable Nanping Fu Bao, the company was founded in 2003, is a set of utilities, electrical, lighting and other home improvement, construction and decoration materials as one of the wholesale, distribution and delivery services for a professional sales company. Our company: 'customer first, forge ahead' business philosophy, the "customers first" principle, switches and sockets, to provide our clients with quality services. At this stage, the emitter current no longer flows, and the collector current becomes negative base current. Because the transmitter switch operation, long storage time is reduced to a few hundred nanoseconds (no storage effect). Once all the base charge have been evacuated, the power level to enter the off-state. Since the storage time is short, the power level can be higher than the standard bipolar transistors operating at frequencies (up to 500KHz), while maintaining a high standard power MOS can not achieve voltage capability (up to 1KV), and conduction losses pole low. Control level and power level are, Vcc pin through a resistor-capacitor (RC) network is connected to the DC bus powered by the Vcc pin. During the startup phase, capacitor through a high value resistor charging, so that only a few hundred microamps. Since the power bipolar transistor base current is stored on the connected Vcc pin through 'Vcc charging network' capacitance recovery, switch, and therefore, in the work phase, the device is a power supply for ourselves. The company's main business: the main agent wholesale Schneider switch, circuit breaker Schneider, Foshan Lighting, Siemens switches, Emmett ceiling fan, Hyderabad Man doorbell, Merlin Gerin switch, Merlin Gerin circuit breakers, Zhengdan inserted, inserted fine arts laborers into place, new home switches, wire and cable Nanping Fu Bao, the company was founded in 2003, is a set of utilities, electrical, lighting and other home improvement, construction and decoration materials as one of the wholesale, distribution and delivery services for a professional sales company. Our company: 'customer first, forge ahead' business philosophy, the "customers first" principle, to provide our clients with quality services. . Lamp: Lamp is an important part of energy-saving lamps, sensor switch, and the quality is good or bad lamp inside the powder mainly composed of the decision, there is usually a rare earth powder, that is, three-Toner (tri-phosphor), switch brands , 300-400 yuan / kg, the phosphor (a few ten-dollar / kg) and mixed powder three, three-Toner have good or bad, imports, domestic points, the mixed powder is mainly tri-phosphor and the phosphor by a certain percentage mix it up, the higher the proportion of three-Toner, the better the quality. A lamp will have a different cost, general phosphor lumen only 40lm / w around [2 switch brands _ switch _ What kind provided by Xiamen Switchgear Co., Ltd. Xing Lu Da Electric. Xiamen-Heron Electric Co. (xmxldsm.1688.com/) is Xiamen, Fujian Materials Stocks leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Xing Lu Da Electrical leadership with the staff warmly welcome all inquiries negotiations to create Xing Lu Da Electrical better future. |
