Certain online UPS Systems have the ability to be connected in parallel in order to provide redundancy. Expressed as an “n+x” system, “n” is the number of UPS needed and “x” the number of UPS over and above the actual power requirement.

Redundancy can also be achieved if your load has dual inputs and providing power by two separate UPS Systems. In such circumstances you could remove the need to parallel the UPS together.

The issue arises with this situation in that if the output voltage waveform are not synchronised they could end up out of phase. For a single phase system operating at a nominal 230Vrms this could mean a potential between two “live” conductors in the same enclosure of 460V!

Usually a UPS output frequency is synchronised to the input power frequency. This allows the UPS to “bypass” without any loss of power in the event of a fault or overload. As a result, the AC power source feeding the UPS Systems must originate from the same supply.

When the UPS drop onto battery power during a power outage their outputs are then controlled by their own internal clocks. A full power waveform is generated in 20 milliseconds. In order for two waveforms to be antiphase there needs to be a time delay between them of 10 milliseconds. In a 5 minute power cut this means that two disparate UPS systems need only have a variance between their clocks of around 30ppm or 0.003% – a tiny amount – for an antiphase situation to occur.

The UPS Systems need to have synchronisation to prevent this from happening, and not all systems are capable of this. The E200 6KVA and 10KVA UPS Systems from Dale Power Solutions have this very important feature allowing the UPS to be independent but have a synchronized output.

When you build your own computer, one of the most important decisions you need to make is selecting the best motherboard for your computer system; the motherboard is a critical operating component. Building your own computer means saving money and it also means that you can build a custom-designed and custom-specified system; you’ll get exactly what you want and need.

The motherboard is a very key part of the overall system; a number of system components connect to the motherboard (mobo). In selecting the best motherboard for your computer build, you need to have a good understanding of your needs: what type of system you want; what kind of demand you will place on your computer (heavy use; heavy graphics; fast operating speed; etc.); and how what you choose affects the operation of your system.

When selecting the mobo, consider which CPU you will be using in your computer build. For example, AMD CPUs require a different motherboard than Intel CPUs because each uses a different socket type. Also understand the impact of processor speed: your motherboard needs to support the chosen CPU.

There are a wide variety of socket types in use; and with the frequency and rapidity of technological changes that will continue to change and evolve. With these changes, come improvements (aka changes) to the number of pins in processors – this results in motherboard sockets needing more pins to provide more power and support new features and benefits. New processor designs have started to put pins on the socket instead of the CPU, which does allow for an easier set-up. So make sure you do your homework and match the right CPU configuration and socket type to the right motherboard; the CPU needs the socket to communicate with motherboard components through the chipset. A number of suppliers offer motherboard and CPU bundles check into those carefully – they can be a good buy but you want to make sure that the bundle provides what you need and want.

Once you’ve decided on your motherboard and CPU package, you will need to decide on your BUS, RAM and chipset. Your chipset needs to be fast for efficient data transfers and power management. BUS size is important because the BUS circuit width or size determines how much, and how efficiently, data can be transmitted. BUS speed is measured in MHz and it determines communication speed; with a fast speed allowing faster running applications and data transfer. The need for speed is driven by new, upgraded applications that typically demand more speed; luckily technology has evolved along with the speed demands. Make sure that your BUS speed is not a constraint issue in your system; you don’t want it to become a bottleneck for your whole system.

You need to consider memory and the need for memory when you select your motherboard for building your own computer. 2 GB of RAM is enough unless you are a heavy user, such as a gamer, or someone who works a lot with graphics or videos. Motherboards today will come with at least two memory slots, and many come with four slots. Buy a motherboard with four slots to ensure you have enough expandable memory capacity for the future (even if you start with 2 GB of RAM). When selecting the motherboard for your system, don’t forget other considerations such as, webcam, digital camera, external drive, flash drive, printer, keyboard and mouse. If you plan on adding additional cards (such as a wireless network card, graphics card, or sound card), the peripherals will require enough PCI slots. Most motherboards have four USB slots and two more that connect to the USB ports on the case. About every four to five years, it is likely that you will need to change the battery in your motherboard and don’t forget the preloaded BIOS which boots up your computer.

The most important aspect of selecting components for your computer system build is to ensure that you build not just a system for today’s needs, but for your future needs. It is very rare for you to be satisfied with a basic, minimal system for more than a short (six months to one year) period of time. Specify and select your components to build your computer system to last you for a minimum three to five years (my last system worked very effectively and efficiently for seven years because I over-built for my needs at the time); in other words, buy as much speed, power, memory, and features and benefits as you can afford – even if you don’t think you’ll need it. As technology progresses and changes, you will find you need the advanced system to sustain your needs.

You can’t be wrong by saying that they are the biggest headphones &earphone company with the largest market share.

What does they manufacture? Well, their product line ranges from ear buds that replace the standard issue Apple earphones, to sports headphones for jogging and cycling, right through to high end full size Hi-Fi models. You can see, they have it all covered. They always refer to itself as the term ‘electroacoustics’ to explain what they really do.

So it is okay for us to draw the conclusion that Sennheiser is indeed the market leader. But people will start to wonder:are Their headphones and earphones any good? Well, I will say yes from my own personal experience.I personally own several pieces from them.Their headphones and earphones are always well made and the sound quality if often excellent. Even the cheap model’s perform is very satisfactory.

Rumor has it in the IT industry that you can’t be fired for using computer and hardware from IBM.And it is the same case with Sennheiser when it comes to headphones and earphones in my opinion.Sure thing is that you just can’t go wrong with them.

But, I warned you,you should always beware of those fake cheap ones in the market. They are definitely no good.You may see very very cheap Sennheiser headphones being offered somewhere. But you should be warned, they are fake. It is often the case that these rip-off headphones are of the lower end , for example CX300 ear bud headphones and are offered at very insane bargain prices.

No doubt these are definitely not genuine ones and you can be sure that the quality is very poor. They might look almost identical to the real ones, but you should always remember that you don’t get something for nothing!

If you are interested in buy sennheiser headphones, you might want to take a look at our online store. We have a wide selection, not just the wireless ones.

When it comes to buying a desktop PC, the size of your budget may be one of the biggest considerations you may have. Depending on how much you are willing to spend, there are plenty of desktop PCs that can easily accommodate your budget. Without a solid budget in mind, it’s easy to become lost in the many different choices and options that come with desktop PCs, whether you are building a system from scratch or buying a pre-built system package.

If you are a light PC user whose main activities include surfing the web and checking emails, a budget desktop PC may be just what you are looking for. For about $300, you can purchase an affordable system from vendors such as eMachines and Acer. Granted that these desktop PCs won’t have the latest features or the most powerful hardware, but for a shopper on a tight budget, these desktop PCs are an excellent choice.

Mainstream desktop PCs start out at around the $500-$600 mark, and they generally have more options than budget computers, although they do not have as much content as their upper level counterparts. These computers often have larger hard drives, more memory and also come with a monitor. Mainstream computers are perfect for those who more than just surf the web and read email – tasks such as CD and DVD burning, plus other light multimedia functions can be done with ease on these machines.

The $1000 mark opens up even more options for consumers, especially for those who are a far cry away from being a professional user yet still wants a decent punch in their desktop PC. These more advanced desktop PCs normally include dedicated video graphics cards that are upgradeable, as well as better and faster processors. Other options include Blu-Ray video drives and larger hard drives and more memory.

At the $1500 and above mark, one can find powerful desktop PCs that are built for power users in mind. These computers can handle large-scale multimedia editing and 3D graphics programs such as 3D Studio Max and AutoCAD. These machines often have a lot in common with gaming desktop PCs, but they are geared more towards business applications than they are towards gaming.

For those who want to have a machine that can play the latest games without missing a beat, gaming desktop PCs are the perfect answer. These machines have the fastest processors, the best video graphics cards and the largest and fastest hard drives available on the market, all dressed up in a special desktop tower case designed for maximum airflow. Of course, these machines often cost a pretty penny, with prices soaring beyond the $3000 mark. If you’re comfortable with building your own desktop PC, it’s possible to build your own machine to the same specs as a $3000 for half the cost.

The vast majority of desktop PCs will come with Microsoft’s Windows Vista preinstalled, although newer systems are appearing with the latest operating system, Windows 7. Only a few manufacturers offer PCs with the Linux operating system installed, usually upon the customer’s request. Nearly all desktop PCs come available with recovery CDs and other rescue tools for fixing most operating system-related problems.
