IsoPlug 是一個多用途的旁通濾波器系統,聯結主電源的 L 和 N。使用簡單,只需將其插入產生電源訊噪的電子裝置旁邊空閒插座,例如電腦、冰箱冷凍櫃、電話充電器等。當電子元件提取電力時,它們會產生差動模式主電源噪音(differential mains noise),而 IsoPlug 有助於減少這種電源污染所產生訊噪。IsoPlug 還可以用於升級簡單的電源排插; 將 IsoPlug 插入輸入供電的第一個插座,然後可以使用第二個插座來分隔類比和數位設備。


IsoPlug is a versatile shunt filter system that goes across the live and neutral of the mains supply. It is easy to use, simply plug into free wall sockets next to noise generating electronics, for example computers, fridge freezers, telephone chargers, etc. When electrical components draw power, they produce Differential Mode mains noise. IsoPlug helps reduce this. IsoPlug can also be used to upgrade a simple power distribution strip; by plugging IsoPlug into the first socket of the incoming supply, a second one can then be used to separate analogue and digital components.

共模噪訊通常被稱為射頻干擾(RFI) – 這是我們周圍有但看不見的傳輸頻率。例如,行動電話、基地台、Wi-Fi 和藍牙系統等等無線頻率讓 “共模噪訊” 不斷增加,想像一下智能手機和平板電腦傳輸的數據量有多大;而廉價的電源線就像天線一樣,接收這些不需要的頻率。

Differential Mode mains noise is created by all electrical appliances – everything with a power supply, in fact. This includes your microwave oven, your television and your computer, as well as every hi-fi component you own.

Common Mode mains noise is often referred to as RFI – transmitted frequencies that surround us but we cannot see. For example, imagine how much data is transmitted by smartphones and tablets; cheap power cables act as aerials (antennas) for these unwanted frequencies.

從高品質聲音的需求來看,電源需要兩個重要條件:1. 必須有穩定的 50 或 60Hz 正弦波,來源要是低阻抗的。2. 沒有無線射頻噪訊干擾。
低阻抗確保無論周圍區域使用多少電力,電壓都能維持相對穩定。然而,實際上我們可能會有約5%的電壓波動。主電力在 50 或 60Hz 時的極低阻抗(低於 1 歐姆)在接近無線電頻率(> 50 歐姆 > 100 千赫)時無法保持,反而充當天線,吸引無線射頻噪訊。

IsoTek 的電力淨化電路的設計目標是在保持安全性的同時,降低阻抗,並在音訊頻率範圍內進行有效校正。這不僅僅是基於良好的電力工程判斷,同時也符合電氣安全規範,經過獨立評估。

From a high quality audio point of view, mains electricity needs two factors; a nice 50 or 60Hz sine wave supplied from a very low impedance source, without radio frequency noise. The low impedance makes for a near constant voltage regardless of how much power is used in the surrounding area. In reality we can typically expect around 5% fluctuation. The very low impedance of the mains, which is way below 1 ohm at 50 or 60Hz is not maintained when approaching radio frequencies (> 50 ohms > 100 kHz) and acts as an aerial (antenna) inviting RF noise.

IsoTek’s power cleaning circuits are designed to reduce impedance whilst remaining safe as well as correcting well into the audio frequency bands. This is not only a judgment from sound electrical engineering, but it also follows the codes of electrical safety, which are independently assessed.

IsoTek 每項產品用的都是頂級電子元件,許多都是特製的,並使用高品質金屬材料。品質的追求不僅止於零件,更延伸至印刷電路板(PCB),該設計能維持高電流輸出和超低電阻,使用的銅量高達一般標準的八倍,再加上純銀鍍層。

內部配線則選用高純度銅結合鍍銀工藝,絕緣材料是航太級的氟化乙烯丙烯(FEP)或 IsoTek 獨有的虛擬空氣 介電(VDA)技術,纏繞 FEP 管再加上 FEP 絕緣層,確保了卓越的傳輸表現,打造出低阻抗、高功率的內部供電系統。

Every IsoTek product uses the finest grade electrical components, many custom made, using the highest quality metals and materials which are specifically designed for purpose. Quality doesn’t stop at parts but also extends into the PCB designs, which maintain high levels of amperage and extraordinarily low levels of resistance, using up to eight times the general standard of copper prior to pure silver plating.

Internal wiring also uses high purity coppers combined with silver plating, with either Fluorinated Ethylene Propylene (FEP) dielectric or IsoTek’s Virtual Dielectric of Air (VDA), where a FEP tube is wound around the conductor before an extruded FEP dielectric protects this construction giving unrivalled performance and the ultimate low resistance, high performance internal power delivery system.

IsoTek 的保護系統配置了一系列壓敏電阻(VDR)串聯防護技術,可提供多達超過 100,000A 的保護等級。根據電源突波或電湧的嚴重程度,快速且順序地介入而當情況需要時,保護電路設計得能立即大範圍反應。

保護電路有兩大主要功能:其一是保護自身,其二是隨著問題的加劇循序介入,對於極端情況則能做出快速反應同時也確保了濾波器的安全,而濾波器在首波保護中也扮演了輔助角色不同於其他保護裝置僅提供保護作用,這些設置還有助於音質提升。研究指出,這樣的問題不僅明顯而且發生頻繁,特別是在 1,000 至 6,000 伏的高壓範圍下更是一大挑戰。許多保護系統未能即時提供足夠的保護,且可能還會影響音質。

Power surges or spikes on the mains supply are generally very bad for any electrical device especially a high quality audio replay system. Power surges occur when there is a boost to the electrical charge at some point in the power lines. This causes an increase in the electrical potential energy, which can increase the current flowing to your wall outlet. This in turn can damage your sensitive audio system.

The IsoTek protection system uses an array of VDRs which offer a cascading level of protection, in some cases over 100,000A. These step in fast and sequentially dependent upon the severity of the encountered power surge or spike. The architecture of the protection circuit extends dramatically and almost instantly when required.

The protection circuit has two primary functions, one to preserve itself and the second to step in gradually as any problem increases, with the ability to act very fast should an extreme condition occur. The protection circuits also protect the filters and the filters assist the protection in the initial stage. Unlike many protection devices these assist sound quality as well as providing protection. Studies suggest this problem is not subtle and is frequent. The disturbing challenge is the 1,000 to 6,000V range. It is likely most protection systems do very little good and probably cause sound degradation.

克希何夫 等效電阻電路 K.E.R.P.

根據克希荷夫的技術論文所示,電路定律是處理電路中電流和電位差(通常稱為電壓)的兩個相等性原則,特別適用於集總電路。這些法則於 1845 年由德國物理學家古斯塔夫·克希荷夫 (Gustav Robert Kirchhoff)首次描述,擴展了喬治·歐姆的研究,並先於詹姆斯·克拉克·馬克士韋的工作。被稱為克希荷夫電路定律(Kirchhoff Circuit Laws)簡稱為克希荷夫定律,它們在電氣工程中得到廣泛應用,形成了電力網路分析的基礎。

IsoTek 對電路的設計受到 克希荷夫的兩個電流定律的引導。簡單的比喻是,如同自來水廠得到一公升水,希望能無損失的輸送出一公升的水!

換句話說,克希荷夫和高斯描述了透過城鎮的概念解決看似不可能的問題。如果交通在城鎮周圍的圓形軌道上流動,對城鎮沒有影響。然而,一旦交通進入城鎮,就會對城鎮產生影響,而進入的車輛最終都必須離開。城鎮的結構將對這種遷移產生正面或負面的影響。在電子學中,這也是一個重要的觀念,我們必須全面尊重 信號路徑,因為無論是否願意,最終一切都將以不同程度存在於訊號路徑中。

Technical papers state that Kirchhoff’s circuit laws are two equalities that deal with the current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff. This generalized the work of Georg Ohm and preceded the work of James Clerk Maxwell. Widely used in electrical engineering, they are also called Kirchhoff’s rules or simply Kirchhoff’s laws. These laws can be applied in time and frequency domains and form the basis for network analysis.

The guiding principles for IsoTek circuits are driven by Kirchhoff’s two current laws, a simple analogy would be that for every litre of water placed into a water distribution system we would expect to get the same out.

To put it another way, Kirchhoff and Gauss described how seemingly impossible problems could be resolved by the concept of a town. If traffic flows on a circular orbital road around the town there is no effect on the town. However, if traffic enters the town, then there will be an effect on the town, and however many cars that enter eventually have to leave. The structure of that town will have either a positive or negative effect on that migration. In electronics this is also true. We must totally respect the signal path as, whether one wishes it or not, ultimately everything will be in the signal path to a greater or lesser degree.

IsoTek 的內部佈線與 IsoTek 電源線系列ㄧ起使用可確保持設計和材料特性的共通性。

As one would expect, the internal wiring of any IsoTek product is of the highest standard, pure 6n OFC (Oxygen Free Copper – 99.9999%) conductor strands with silver-plating offer low resistance and high amperage. An FEP dielectric is used to protect the conductors as well as giving the ultimate internal power delivery system.

IsoTek’s internal wiring synergizes with the range of IsoTek power cables. One critical but overlooked area is maintaining commonality of design and material properties though an audio wiring loom, be it signal carrying cables or your power cable network.

IsoTek 致力於 提供充沛且穩定的電源供應,即在電力公司 法規允許的供應範圍內無限制的輸出電流。 IsoTek 設計的電源對於功率擴大機或高功率電子設備來說,能夠提供低阻抗和低直流電阻(DCR)的輸出,這樣可以避免電流受限並提升器材的動態表現。當電源 受到污染時 時,器材的動態範圍也會變差而且到電站之間 的迴路阻抗遠高於此。

從交流電源供應中獲得超過 100% 的輸出是不可能的。依交流電的基本原理是輸送電能而不是存儲能量,而且根據交流電運作原則,是不可能存儲能量。所以「電源儲備」在交流電路中本質上是不存在的,也不可能存在。

電源儲備所需的電壓會隨著歐姆定律增加,並不是說電壓不下降就是電能儲備。交流電(AC)波形在 50Hz 時,每 10 毫秒就在最大值和最小值之間變動,20 毫秒完成一整個週期。因此,實際上交流電(AC)波形的平均值為零。只有轉化為功率波時,由於負數平方變正的原則,而成為正值。以波形來看就像一個膨脹的正弦波,此時 45 度的值為 0.5,而不是三角形函數表中的 0.7071。如果只談電壓波,它長期來看是沒有值的,也就是零!所以談到能量儲存,實際上儲存的能量是零。

直流電阻(DCR)會電壓下降。換句話說,需要開發一個不限制發電站電力儲備的系統,這意味著電路需要在高感抗的同時,並具有極低的阻抗。如果方式正確並保持平衡,那麼在 50/60 Hz 時感抗幾乎為零,直流電阻(DCR)也非常接近零。因此,理想的過濾電路必須保持直流 0Ω 阻抗(或非常接近),並對高於 50/60 Hz 的噪訊具有相當的的交流阻抗。這正是選對材料規格最重要的地方。即便有時
候可能需要用到一些極其特殊的材料,但在重要的關鍵部分,是非常適合使用的。值得註意的是,IsoTek 的濾波設計可以在 50/60 Hz 保持極低的阻抗,但在該頻率上卻有極高的噪訊消除能力。

大多數交流電路不僅僅含有電阻元件,還會表現出電阻結合電容或電感的特性。在理想狀況下,電路中唯一允許存在的阻礙應當是電阻,且電阻值要極低,這就帶來了一個難題,是否追求高的暫態功率,還是要強大的淨化濾波能力來消除雜訊。驚人的是,確實可以兩者兼顧,但要實現這一目標,就得依靠那些極高品質、專為此特定目標設計和結構完全正確的元件,這些高度複雜並專業的元件,僅在特殊領域中才能找到,而 IsoTek 的優勢在於其有能力設計出這些獨特的電子元件。

IsoTek delivers absolute power, unrestricted current delivery within what the power company can supply, and regulations allow. Generally, for power amplifiers or high wattage electronics IsoTek provides output which offers extremely low impedance and low DCR, this completely eliminates (within the concepts of power filtering) any possibility of current restriction and enhances dynamic range, the impedance of the chain back to the power station being far larger. When power is contaminated, dynamic range is reduced.

It is impossible to get more than 100% out of the mains supply. The very principle of AC power is that it doesn’t store energy in the transmission system. It is therefore impossible to store energy in an AC system by the very principles by which it works. There can be no so-called power reserve, thus a power reserve within an AC circuit in the truest sense of the word does not and cannot exist.

Power reserve would require the voltage to increase as ohms law insists it must, saying a circuit doesn’t sag isn’t a reserve of power. The AC waveform goes between maximum and minimum points at 50 Hz in 10 mS, it then swings to the maximum negative value. At 20 mS a full cycle is achieved. Therefore, in fact the average values of an AC waveform is zero. Only as a power wave can it be positive, this is due to the law of squared negatives. It looks like a ballooned sine wave where the value of 45 degrees is 0.5 not 0.7071 from a trigonometric table. Were this only a voltage wave it would have a long-term value of zero! As far as energy storage is concerned zero is the value of stored energy.

Direct Current resistance (DCR) will cause sag. To put it in other words, a system has to be developed which does not limit the power reserve of the power station, meaning a circuit needs to have extremely low resistance whilst maintaining sufficiently high inductance. When done correctly and in perfect balance the inductance is virtually zero at 50/60 Hz and the Direct Current resistance (DCR) is also very close to zero. Therefore, an ideal filter circuit must maintain zero Ohms resistance DC (or very close) and considerable AC resistance to noise above 50/60 Hz. Despite statements to the contrary, this is precisely where correctly specified materials matter most. Whilst some might consider these ‘exotic’ they represent a critical and important part of the function and appropriate to use. Remarkably IsoTek filter designs can maintain very low resistance at 50/60Hz but have very high amounts of noise cancellation above that frequency.

Most AC circuits are reactive – produce a reaction either from the power drawn or the circuit itself, put simply they are not pure resistors and behave like a capacitance and resistance or an inductance and resistance. In an ideal world the only allowable impediment is resistance and ideally this needs to be extremely low. A dilemma, do you want high transient power, or do you want heavy filtration – amazingly you can have both, but one must have components of the very highest quality, which are designed specifically for purpose with totally correct architecture. This is extremely complex and has resulted in the design of specialist parts; these do not exist outside the world of specialist power engineering and are unique to IsoTek designs.
