Choosing the Right DC power for your application
The power supply CC is a rather fundamental electronic device, but there are hundreds of DC power products on the market from dozens of manufacturers. Limiting the best product for your application and budget can be a daunting task. This article addresses DC Power Supply differentiators, functions and applications they are best suited. focus of the article is DC power supply used by engineers, manufacturers, quality professionals and amateurs electronics for R & D, manufacturing and testing.
Power can range in price from $ 50 to $ 20,000 and the cost is often directly proportional to the energy release of the device. The main function of a power supply to regulate the output voltage and current. It requires a power input and regulates the output power to apply a constant voltage and current. In the case of DC Power Supplies, the input power is converted into alternating current (AC) to direct current (DC). There are two basic types of regulated DC power supplies: linear and switching.
Linear power supplies can never output a higher voltage than the input source. In theory, a linear power supply which is driven by a typical 110V outlet 110V outlet could not, assuming that the device was 100% effective. Realistically, no power supply is 100% because power conversion always results in energy loss, usually in the form of heat dissipation. Therefore, the linear power usually provides output voltage which is well below the entrance.
SMPS can step-up step-down or reverse the input voltage. SMPS are generally larger, noisier and more expensive than their linear, however, SMPS are generally more effective.
Choice of DC right for your application requires the definition of certain basic design specifications: voltage range, current range, the number of exits, clean power (known as "drive") and programmability. In general, the higher the output voltage and low ripple, the most expensive food in DC. Multiple output and programmability features will also add cost.
The cheapest DC Power Supplies are ideal for electronics hobbyists and basic applications electro-mechanics, where only power is required. It is likely that the devices being supplied in these applications have characteristics power conditioning that eliminates the need for an input power of precision. Low power, single output, DC power supplies the Prices range from $ 50 to $ 200.
mid-range power supplies are suited for non-critical laboratory projects involving more applications advanced electro-mechanical or base board level test. Midrange power can have multiple outputs, more power, lower training and precision digital measurement (+ / - 0.001 V, + / - 0.01 A). Mid-range DC power supplies can be linear or switching and could range in price from $ 200 to $ 1000.
high-end applications requiring high output voltage, programmability Extended (PC GPIB interfaces), many outputs and very low ripple should budget of over $ 1000 for their current supply. Many laboratory Applications R & D and testing could easily spend $ 5,000 to $ 10,000 per feeding.
This article has presented some characteristics base and applications of DC Power Supplies. Before making your final purchase, be sure to check with the manufacturer and understand all the specifications of a particular product. Choose the best and most economical DC Power for your application should not be a complex and lengthy task. By identifying your design parameters, you will quickly refine the selection of niche products in a category of products from only a few manufacturers.
