Venom Defender .. A POCKET POWER CONDITIONER

จากผลงานของ Shunyata USA. บริษัทที่บอกกับตัวเองว่าจะยึดถือความเป็น Passive ไม่อั้นไม่รั้ง ไม่หน่วงกระเเสไฟฟ้า

เสียบ Venom Defender ในชุดเครื่องเสียงของท่านเพื่อสนามเสียงที่เงียบเเละสะอาดกว่าที่เคย

The Venom Defender is small and compact; has no chassis, no outlets and no power cord. You simply plug it into the wall outlet and it provides noise reduction and transient protection to your system.

ราคาตั้ง ชิ้นละ 13900.-

There is no "voodoo" related to any of our products. Their operation, technologies, parts and the POV of design are explained in detail on our web. We also have a complete document that explains theory of operation and the distributed power conditioning approach, of which he Defender is a part. The Defenders are now used in Hospitals and have a measurable effect in reducing line-noise -with no ill-effects. It's safe to say that they perform as they are designed to. That said, what effect they may have in your system should be experienced before purchase or with a return-privilege. They are not intended to be a panacea and their overall effect may vary depending on your system and electrical conditions. As for your questions, hopefully the following answers some of them.

Generally speaking, a typical power line circuit has three conductors. There is the voltage supply wire (HOT or L1) and there is a return line which is called NEUTRAL or L2. The last wire is the GROUND wire or Safety Ground.

The power grid acts as a "constant voltage source". This means that the current is determined by the demand from the load (component 's power supply). The power circuit in the wall can be expressed (described) in a schematic diagram as a distributed series, parallel circuit. Specifically there is a series resistance and series inductance with an associated parallel capacitance. Because the circuit has this distributed impedance there are limits to the power grids ability to maintain a constant voltage level when the load presents a near zero ohm impedance. If the impedance of the load drops to a very low level the voltage of the power circuit will drop.

So to answer your questions you need to understand that all components that you plug into the power circuit are electrically in parallel to one another. If any of the components on the power circuit presents a low impedance then the voltage on the entire power circuit will be lowered. The Defender's noise reduction is achieved with a parallel filter array. This lowers the noise level on the entire power circuit not just at the electrical outlet.

The Defender also includes an advanced type of thermally protected metal oxide varistor called a NEXTGEN TMOV. These devices react to transient voltage surges by shorting the HOT and NEUTRAL together which presents a temporary zero impedance load. This effectively limits the voltage surge to a reasonable level. Since the power line is a distributed series, parallel circuit the TMOV is quite effective at limiting a voltage surge at the wall outlet. However, we do not recommend relying on a Defender as a total surge protection solution. We always recommend that you install whole house surge protection which is installed at the service entrance. This will protect ALL of the electronics in the home. We consider the Venom Defender to be primarily a noise reduction device with a supplemental surge solution for handling local surges that are generated within the home by heating, air conditioning systems, refrigerators, power tools and other electronics that may malfunction.

Of all the Defenders sold (well over 2000), I am aware of fewer than 5 that have self-destructed in the interests of system protection--and no reports of failure to protect components plugged into he same line. Just make sure the Defender is upstream, electrically and on the same outlet (line) as the electronics you wish to protect.
