Application Interface: DC motor debugging, testing, aging and linear regulated power supply different class of stable power supply is switched-mode DC power supply, it's a circuit pattern mainly single-ended flyback, single-ended forward, half-bridge, push-pull and full bridge. It linear power transformer fundamental difference is that it does not work at the power frequency but in tens of kHz to several MHz. Function tube is not in saturation and cutoff switch that state; switching power supply, hence the name. DX Series DC stabilized power supply, DX series DC stabilized power supply price, DX series DC stabilized power supply manufacturers, DX analog cell characteristics power supply manufacturers, DX analog cell characteristics power prices, Shanghai JJW AC clean power Price, JJW exchange purification power producers, Yangzhou AC power supply manufacturer, AC power supply production factory, DX magnetic pole pairs detector price, DX magnetic pole pairs detector manufacturers, DX magnetic pole pairs detector manufacturers, electrical test equipment manufacturers, electrical test equipment manufacturers, electrical test equipment manufacturers price, Yangzhou DX series DC electronic load, Yangzhou DX-8 AC electronic load box, DX Series DC Electronic Load manufacturers, automobile generator test instrument manufacturers, automobile generator tester price advantage magnetic switch tester manufacturer of switching power supply is small, light weight, stable and reliable; shortcomings with respect to the linear power supply ripple is large (typically ≤1% VO ( PP), can be a good dozen mV (PP) or less). It's a few watts of power can be self - are the product of several kilowatts. The price of 3 yuan - more than ten million / watt, here are some general habit of switching power supply on classification: 1) AC / DC power supply, also known as a kind of power, it has made since the energy grid, after getting a DC high voltage rectifier filter high pressure, for DC / DC converter at the output to obtain one or more stable DC voltage, from a few watts of power - are the product of several kilowatts, for different applications. Is such a product specification model range, according to user needs in one communication power supply (AC220 input, DC48V or 24V output) also fall into this category. 2) DC / DC power supply in the communication system, also known as a secondary power source, It is supplied by a DC power source or a DC input voltage of the battery pack, the subsequent DC / DC converter at the output terminal is eligible for one or more DC voltage. 3) communication power communication power it is essentially DC / DC converter power supply, but it is generally DC -48V or -24V power, and for DC-powered backup battery backup, the DC supply voltage converting circuit voltage generally it divided the central power, hierarchical power supply and three kinds of boards, the latter for maximum reliability. 4) radio station Power supply input AC220V / 110V, output DC13.8V, power from the power supply units may be several hundreds of security products are safe. In order to prevent power outages AC radio work, and the need for a battery pack as backup, so this type of power supply in addition to a 13.8V DC output voltage, but also has a battery charging automatic conversion. 5) module power as the rapid development of science and technology, the reliability of the power supply, capacity / volume ratio increasing requirements, power supply module has increasingly shown its superiority, its high operating frequency, small size, high reliability, ease of installation and a combination of expansion, so more and more widely used. At present, although the current domestic production of the corresponding module, but failed to catch up with international standards of production processes, high failure rate. DC / DC power modules, although currently high cost, but the overall cost of a long period of application of the product, in particular the high maintenance costs and loss of goodwill due to system failures of view, the choice of the power supply module or cost-effective cost-effective, this is also worth mentioning that Roche converter circuit, its advantage is a simple circuit structure, high efficiency and output voltage ripple current value close to zero. 6) Special high-voltage low-current power supply, high-current power supply, 400Hz input AC / DC power supply, etc., can be attributed to such, can be selected according to specific needs. Switching power supply is generally priced at 2-8 yuan / watt special low power and high-power power prices higher, up to 11-13 yuan / watt.
