How to choose a DC power supply for automated test systems

Each automated test systems for testing circuit boards, modules or devices require one or more DC power supply is used to provide power to the device under test and provide test stimulus. In some cases, the power supply provides power not only to the device under test, but also to provide the test excitation source via a simulated work environment. For example, although most automotive electronic equipment in nominal 12VDC, but the maximum input voltage may be as high as 27VDC. Because of this, some car standard requires 12VDC up to 27VDC devices limit testing. Determines the necessity like power requirements. Let us look at the common power supply specifications when selecting the power of automated test systems need to consider what?

Linear power supply or switching power supply?
Decisions when buying a DC power supply is the first to make a choice of linear or switching power supply. Linear power supply with low ripple and noise, and has a fast transient behavior. However, their low efficiency, will produce a lot of heat, and heavy. So most of the engineers found only at lower output power levels (usually 500W or less) when comparing desirable. Most linear DC power supply desktop power supply.

Linear power for the desktop, the application is a very suitable test communications device such as a mobile phone or radio or radar system demodulation module. These devices have a very sensitive discriminator or demodulator circuit, these circuits at low noise figure to play the desired performance. To test the true performance of these units, we need to ensure that the DC power to the test device does not add any spurious noise. Since the linear power with lower than the switching power supply output ripple and noise, so they are a better choice for such applications.

When the power requirements low, linear power supply is also a good choice. The main benefit of switching power supply can only manifested in higher output power level talent. Therefore, the DC output power per channel does not exceed the application requirements of 100W to 200W linear DC power supply used in more cost effective.

From this point of view, considering the total DC power output of all channels of the system is very important. If there are four or four of the following channels, and power requirements are relatively low, then the more sensible choice is to form 19-inch rack mount kit provides four linear power.

If your system requires more output channels, or higher output power, then use the switching power supply is a better choice. Switching power supply can provide a higher power than the linear power density. By using a switching power supply, you can have 12VDC output, and can be installed in the same rack configuration provides up to 4000W of power. Switching power supply is easier to control than the linear, while the cost per channel almost.

Even in requiring low output ripple and noise applications, not just more efficient switching power supply. Recent developments in the field of power electronics (such as zero switch), which greatly improved the ripple and noise performance switching power supply. When you also consider switching power supply is more flexible than linear power supply, and can provide higher power density, then they will become the first choice for almost all applications except for a few applications outside.

Upstream Suppliers of Electronic Products Launch New Customization Service

As far as the upstream suppliers of mobilephone business as well as flexible printed circuit board industry are concerned, the competitive market at the moment is equally a brand new opportunity to both. In order to survive the market, and make achievement, FPC cable manufacturers must improve their own enterprise core competitiveness, and make full preparation, to win marketing shares among so many competitors. Besides, they can sieze this opportunity to enlarge their business scale and promote enterprise comprehensive strength.

At present, 4G product manufacturers are all well-known domestic large-scale enterprises, such as Coolpad, Huawei, ZTE, etc. Some FPC cable manufacturing factories that used to supply cables for such large enterprises are expecting a double production value this year.

With so rapid development and promotion, the current FPC cables are reliable and durable. Because of its small volume and flexiblity, FPC cable saves a lot of time for its large quantity production installation. FPC cable also turns more suitable for electronic products due to its waterproof, quakeproof, soldering and heat resisting. Besides, the FPC is also characteristic for its easy bending, winding and folding.

There is a sharp increase on the growth of FPC cable customization project in manufacturing factories. More and more cable manufacturers customize cables' design and other specification of cables when they come to an agreement with their customers on the requirements on the cables to be customized.

The most frequently-seen daily issues businessmen meet with are commonly meetings, and social exchanges in this society today. These activities are usually labeled as tedious and meaningless, and formalistic. Personally, I prefer simplification and performing orientation.

However, annual exhibits are still crucial to new products promotion. Different from those tedious and meaningless lectures and business experiences exchanges, electronic product exhibits are obviously more practical.

It's definitely reasonable and necessary to those who are desired to launch their new products and promote their brand. In a way, products released in exhibits will attract many potential customers and create large-scale sales possibilities.

Along with promotion of the comprehensive technological level, many manufacturers start to lay emphasis on cables from their suppliers. Like the flexible printed circuit cable some manufacturing factories supply, is of high flexibility, good for assembly, foldable and bendable. Moreover, the FPC cable can easily adjust its shape to attach to a certain space for precise electronic products.

Further more, the FPC cable has high temperature resistance, stable chemical change and high safety and reliability. The convenience in assembly is good for the design and installation of the products the cable used in.

Therefore, thanks to their upstream cable suppliers, large enterprises have reliable cables and other accessories.
