The electronic measuring instrument is widely used. Take the dc electronic load as an example Wholesale NFL Jerseys From China , it’s widely applied in the field of LED driver, power module testing, chargers and UPS production. It has become the essential test equipment in these areas.


Electronic load enjoys the load function achieved by electronic devices, and the output port is in line with Ohm law. Specifically, the hipot tester is a device, which makes the power tube have the power dissipation and power consumption by the way of controlling the internal power device MOSFET or the transistor conductor flux. Electronic load generally include the constant current Wholesale NFL Jerseys China , constant voltage, constant resistance, constant power, short circuit, dynamic load and other variety of modes, and it can simulate various load conditions.


Electronic load as a professional equipment to test power Wholesale NFL Jerseys , is flexible to operate. It’s convenient for users to analyze the various date by the full graphical interface of software. In addition, its integrated application not only can form the automatic test system with the high-speed data acquisition, but also can protect the tested equipment fully.


The application examples of electronic load are as follows.


First the manufacturers like LCD computer component can use the electronic load to achieve its internal power supply module testing and aging.


Second the manufacturers of switching power and led can use the electronic load to achieve the test of power supply stability, load stability, the output voltage regulation and the transient characteristics parameters. (Multi-output power supply can be used to the combined attaching test.


Third, the application of the manufacturers of adapter and charger are as follows. It’s very important to test the regulation capability of output voltage and current Wholesale Jerseys Cheap , because it can guarantee the correct supply and battery charge of equipment. You can do the routine performance test in CC and CR modes. Also you can use the OCP and SHORT functions to test the protection movements of products. The adjustment time, charging time etc of charger can be set by loading time of electronic load.


The electronic load is a more widely used in the electronics manufacturing and application area test equipment. Now we can illustrate the examples. In the hot spot test of solar energy panel, the electronic load is often used. in the cell temperature test of outdoor hot spot panel, put the nonopaque panel in the open air, and expose it under the radiation source at 700W•m-2 at least. Test its I-V performance and the current Imp at the maximum power point. Or make the panel have short circuit, put the panel under the stable 700W•m-2 at least. Use the infrared photography to measure the hottest cells Wholesale Jerseys Free Shipping , and record the temperatures. Under the same radiation source, the change of radiation is less than 5% in the period. Connect the positive and negative poles of electronic load with the one of panels.


DC electrical safety tester includes the constant current, constant voltage, constant resistance and constant power the four test modes. In general, we’ll select the constant current test mode, because it facilitates to input different components of operating current. The goal is to test the hot spot cell working under different current Wholesale Jerseys From China , record the hot situation. Such way facilitates to set the temperature requirements of solar energy pane to hot spot. At the same time, it also facilitates the measurements of a variety of hot spots under the continuous irradiations in the room.

Getting the right bicycle tools to purchase might be a little harder than you think. Newcomers to serious cycling often just go out and get a multi-tool that has as many tools on it as they can get, just so they'll be covered in any situation.

But the thing is, they won't know how to use half the tools, and they'll probably never use two-thirds of them. So they spend more money than they need to, and then they carry extra weight all the time on their bike.

Your choice of tools depends a lot upon how handy you are with tools and how much you want to learn about repairing and maintaining your bike. If you're a novice but you really want to learn Wholesale Jerseys China , then obtaining a multi-tool and a few other tools is probably a good idea, in particular if you plan to tour on your bike.

Multi-tools can be awkward to use. Oftentimes, the multi-tools that are designed to perform the most tasks are also the worst at any one particular task. Some cyclists like using specialized tools that are more effective and are simpler to use, even though it means they have to carry extra weight and bulk.

The amount of maintenance you perform at home on your bike also matters.. If you perform regular maintenance on it, you more than likely won't have to do major repairs on the road, so you won't have to carry as many tools. Of course you'll have to carry stuff like tire levers and screwdrivers Wholesale Jerseys , but nothing fancy will be needed.

But if you plan on taking long trips regularly, you'll almost have to get a multi-tool and start learning how to use it. If you're going to tour with other non-mechanics, you can each learn a separate aspect of bicycle maintenance and repair and help each other out.

The best way to learn to become a bike mechanic is to tour with someone who is one, and watch everything he or she does, asking questions when necessary.

Whether you get a multi-tool or individual tools, you'll need Cheap Football Jerseys , at the bare minimum, the following:

• A variety of Allen wrenches; the sizes depend upon your bike.
• A crescent (adjustable) wrench or assorted open or hex wrenches (normally 8, 10 and 15mm, depending upon the bike)
• A flat screwdriver
• A Phillips screwdriver
• A bottle opener
• Tire levers
• A mini-pump or CO2
• A Spare tube and a patch. Cheap Jerseys From China Cheap Jerseys China Cheap Jerseys China Cheap NBA Jerseys China Cheap NFL Jerseys From China Cheap Authentic NFL Jerseys Cheap NFL Sports Jerseys Cheap NFL Sports Jerseys Wholesale Jerseys China Wholesale NFL Jerseys
