Selecting the most appropriate DC Power Supply for your Application

The DC Power Supply is a rather essential electronic device, however there are hundreds of DC Power Supply products on the market from dozen of manufacturers. Narrowing down the greatest product for your application and budget can be a daunting task. This article addresses DC Power Supply differentiators, functions as well as the applications they are best suited for. The article’s focus is DC Power Supplies used by engineers, manufacturers, quality professionals and electronic hobbyists for your purposes of R&D, manufacturing and testing.

Power Supplies can range in price through $50 to $20, 000 and the cost is often directly proportional towards the amount of power the device outputs. The main function of a power supply is to regulate output voltage and current. It takes an input power and manages the output power as to enforce a constant voltage and current. In the case of DC Power Supplies, the input power is converted from alternating current (AC) to direct current (DC). There are two basic types of regulated DC Power Supplies: Linear and Changing.

Linear power supplies can never output a higher voltage than the input supply. In theory, a linear power supply that is driven by typical 110V wall outlet could only output 110V, assuming the device were 100% efficient. Realistically, no power supply is 100% efficient because power conversion constantly results in energy loss, usually by means of heat dissipation. Therefore , linear power supplies usually output voltage that is significantly less than the input.

Switching power supplies can step-up, step-down or even invert the input voltage. Changing power supplies are usually larger, more noisy and more expensive than their linear counterparts, however , switching power supplies are typically more efficient.

Choosing the right DC power supply for your application requires definition of some basic design specifications: voltage variety, current range, number of outputs, energy cleanliness (known as “ripple”) plus programmability. In general, the higher the output voltage and the lower the ripple, the more expensive the DC Power Supply. Several outputs and programmability features will likely add to the cost.

The least expensive DC Strength Supplies are ideal for electronics hobbyists and basic electro-mechanical applications where only raw power is required. It is likely that the devices being powered in these apps already have power-conditioning features that get rid of the need for precision input power. Reduced power, single output, DC power supplies range in price from $50 to $200.

Mid-range power materials are best suited for non-critical, laboratory tasks involving more advanced electro-mechanical applications or basic board-level testing. Mid-range power supplies might have multiple outputs, increased power ratings, lower ripple and precision, digital metering (+/-. 001V, +/-. 01A). Mid-range DC energy supplies can be linear or switching and could range in price from one-hundred dollar to $1, 000.

High-end applications requiring high output voltage, superior programmability (GPIB PC Interfaces), numerous outputs and very low ripple ought to budget in excess of $1, 000 for DC power supply. Many laboratory, R&D and testing applications could quickly spend $5, 000 to $10, 000 per power supply.

This article features some basic features and programs of DC Power Supplies. Before making your final purchase, be sure to consult the manufacturer and thoroughly understand all the specifications of a particular product. Choosing the best and most economical DC Power Supply for the application does not have to be a complex plus time-consuming task. By identifying your own design parameters, you will quickly thin down product selection to a niche market class of products from just a few manufacturers Here’s more on roi look into our site.
