Surge Suppressor
? The first line of defense
all home theater equipment must be equipped with at least one form of protection. Surge Suppressor are the most basic protection of power? The first line of defense for all sensitive electronic equipment. Please note that the increase in tension alternating current, or lightning, it can lead to disaster - the turning expensive equipment smoking in a variety of plastic and metal. Investing in a well protect the value is certainly much cheaper than having to replace expensive electronic home entertainment. The wide range of suppressors available on the market for an even wider range of price levels can make the process of selecting a protective device is far from simple. Many of these Surge is the same as a non-technical person - with almost nothing to distinguish the cheapest of the best. In its simplest form, often surge as an increase in low-cost multi-band protected outlet. More expensive units typically incorporate a further increase in protected connections to the telephone line and coaxial TV, some devices include an increase LAN connections, too. In other words, which interconnects with his team would first go through the protection circuits rise to power strip.
surge suppressors work
The basic principle behind the surge are high-voltage transient in nature, while absorbing this potentially destructive energy. This energy is dissipated as heat - and thereby protect the vulnerable circuit components and damage prevention system. In the case that increasing the duration of several milliseconds, may also cause enough current trip to the home circuit breakers or fuses blow the team, therefore, protect your computer. Suppressor surge are usually a mixture of components to suppress the increase of tension. But most of the components used in other protection circuits are Varistor metal oxide (or mov). The MOV is not the only component of greater protection? -- Pipeline surge arrest, avalanche diode (similar effect Zener diode), and type of circuits using the passive reaction inductor and capacitors, which have all the electrical properties that are necessary to cushion the behaviour of transition. Not
of these devices represent the perfect Suppressor. Some lack speed, while the others? as a diode slides? but extremely fast to act, have a limited capacity to absorb energy. For this reason, increased trade protection devices combine several of these technologies will take place in several stages, Suppressor to prolong life and improve response time.
Suppressor Poll
This discussion will not be complete without highlighting some key parameters that define the possibility of a Suppressor; their UL listing, voltage, current peak increase, and the power of manipulation.
IEEE 1449 Underwriters Laboratories See:
is known as UL 1449 or simply UL listing, represents a set of specifications that determine whether a Suppressor is safe to use. Make sure that the chosen Suppressor is described as UL-listed transient voltage Suppressor (TVSS) 2 edition. UL A-list as Power Play is not enough. UL-TVSS list does not imply protect your computer against surges, but rather that the shield is not likely to pose a danger to staff, for example, the use of electrocution, fire, etc.
operating voltage:
The decrease blood pressure of a Suppressor, the most effective protection of Suppressor provides, however, rated voltage must be in conformity with the application form. In particular, some tensions Suppressor should allow normally peak AC voltage present on the line? It is 1414 times greater than the value effective.
Peak Surge current:
, which represents the highest current transition Suppressor who can deal during a wave.
Joule Note:
, also known as energy qualification , it is a measure of the ability to absorb the energy of the wave protective device . Typical values range 500 - 3000, and more. Over the joule rating, the best Suppressor capacity to absorb the energy peaks in the line.
a warning
is well designed, remove the devices can work more and more, but ... Do not take
devices themselves. </ B> Be careful because cheap packaging line power, and other protective equipment. Suppressor Some components are used in these devices are usually one time only. This means that the system can eliminate completely unprotected for an increase.
Quality:
The quality of a Suppressor is reflected in the price of protection, but not only. Watch the classification of July, custody to get an indication of how much damage Suppressor energy can manage. Over the joule rating is better. It should be noted that, contrary to UL-1449 listing, there is no evidence standard method for determining the energy of an opinion Suppressor. Therefore, not based on the joule rating alone? see also in the nucleus of quality and in particular to ensure that the product.
Warranty:
In addition to the standard product warranty, some manufacturers also offer a computer command of the product. This is normal in the region of tens of thousands of dollars. In the longer term, greater security and equipment connected value reflects a higher level of confidence by the manufacturer who Suppressor can protect your expensive home theater art. Try to get to Suppressor devices that come with at least 5 years warranty period and a minimum of $ 10,000 ($ preference 25000), connected equipment warranty.
performance:
The increase in suppressor performance degrades with each increase is absorbed. The problem here is that the rate of degradation is completely unexpected given the unpredictable nature of the wave. Surge rise time, peak voltage, the energy level and duration, each with a varying effect on the further protection of electrical circuits. An increase in May have a higher level of energy that can manage Suppressor, resulting in the destruction of Suppressor zero and protection against possible future outbreaks. To minimize this risk, high-quality equipment, protection normally be able to make use of the most valuable elements of protection circuits - which allows multiple pushed to implement without damage to equipment. Surge Suppressor
rays are not protective devices:
surge suppressors can provide adequate protection of normal wave of AC power lines. Protection against lightning is a totally different story. Not Suppressor device can provide the necessary degree of protection in this area.
personnel security:
Make sure Suppressor is clear that the tension transitional UL (2 edition). This will reduce the risk of injury, fire or electric shock during a wave. At the same time noted that the list UL-device is not a guarantee that will protect your computer.
Conclusion:
In fact, surge is only a first line of defense? do not provide protection against fluctuations in voltage and noise on the line can seriously degrade the performance of AV equipment. Surge Suppressor should be a part of a total protection solution? the use of packaging line and AC-regenerators, with an appropriate assessment Suppressor undoubtedly lead to a more holistic approach to the protection of expensive electronic equipment. Obviously, there is a price to pay for power protection, but it is literally - an ounce of prevention can save you a big headache on the road!
