VESA Standards For Panel PC Mount
Whether one is considering the traditional closed frame or industrial open frame display to be their optimal solution for their application; one must also take into account on how they will manage to mount their display. Most closed and open frame industrial panels provide a panel mount. However, there may be instances in which the panel display needs to be mounted from the rear. This type of mounting interface for a panel PC is usually not some arbitrary design. If that is the case, then mounting the panel display could very well be the most difficult part in designing your application. The Video Electronics Standards Association, better known as VESA, provides technical standards for panel mounts which is usually referred to as a VESA mount. This standard is defined by 7 sizes each with more than one variant. By having such standard, it allows the integrator to design their enclosure to adhere to a particular VESA mount to help simplify the process.
For many of today’s demand on digital signage applications, a closed frame industrial panel PC might just be the answer. However, it is important that the touch panel is reliable and durable even in high touch operating environments, as well as rugged enough to endure harsh conditions. For other integrators, the option of having an open frame solution can minimize workload and eliminate unnecessary disassembly, plus it can also ease the process of designing their enclosure to integrate with the panel. Furthermore, the panel mount minimizes the frustration of having to design the enclosure, knowing there is a set of VESA standard mount to take into consideration. By taking advantage of any of these 3 possibilities, you can customize an optimal design and solution for your touch panel application.
A power adapter that generates the 5 volt DC standard required by USB. The amperage varies, typically from .07A to 2.4A. The charger plugs into an AC outlet, and a USB cable plugs into the charger. USB ports on computers have an upper limit of 500 milliamps; however, USB chargers that come with cellphones and other devices handle one or more amps. The devices sense when they are connected to a computer versus the charger and regulate their current draw.
USB chargers connect to the cable via a Type A USB socket. Geared to the device, the cable has a smaller plug at the other end
Open up a typical charger and you find a couple of chips and several discrete components.
Chargers Are Everywhere
Passengers can charge their devices by plugging them into this USB port on the back of the seat in front of them.
DO Choose the Right Type of Extension Cord for Your Needs
Extension cords fall into three broad categories: occasional use, frequent use, and rugged use. To make sure you find the right types of extension cords for your needs, check the packaging or the cord itself for these designation letters:
indicates general-use cord goods for indoor applications.
indicates a cord designed for outdoor use. The biggest difference between indoor and outdoor extension cords is the insulation. Outdoor versions have bright orange rubber, plastic, or vinyl covers, while indoor cords are much less heavy-duty.
means the cord has standard 300-volt insulation. If you see no J designation, the cord is designed for heavier use with 600-volt insulation.
indicates a household extension cord with parallel wire construction.
means the cord jacket is made of vinyl thermoplastic.
means the cord jacket is made of thermoplastic elastomer rubber (TPE).
indicates an oil-resistant cord.
DO Buy Three-Prong Plug Extension Cords
Standard extension cords are available with either two or three prongs. One prong is “hot,” the second is “neutral,” and the third serves as a path to the ground wire. This third prong drastically reduces the risk of shock and electrical fires by giving power surges a safe place to dissipate.
Of course, you can only use three-prong extension cords with three-prong outlets. If your home has outdated electrical wiring, you may need to upgrade it before converting your outlets to newer three-prong versions designed for enhanced electrical safety.
DON’T Overload Your Extension Cords
Extension wire has a maximum amperage rating, or a limit of electrical current it can safely conduct. Check the device you plan to connect and choose an extension cord with an amp rating higher than the device. If you plan to connect multiple devices, add up all amp requirements to ensure you don’t overload the extension cord.
