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0 Ω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.
