TECHNICAL SPECIFICATION
1. BP-Series Product 3. Warranty card
2. AC Power cable 4. User manual
Here is a typical AC circuit connected to an impedance load: (Please see below Structure)
Note the components. There is a "hot" conductor (120 V.), a neutral wire (0 V.) and a ground
wire. Along with the load, these are the essential components of an AC circuit. Also indicated
in the diagram are reactive currents that are typically present in the power circuitry with every
non-linear load application. Reactive current is basically capacitively discharged energy that
is keyed to a modulating AC source -- a "backwash" of non-active power. This is wasted
energy that is not being actively processed by the load. The important thing to understand
here is that reactive currents are natural phenomena. Unfortunately, the thrust of modern
power quality engineering has been to methodically "undo" what nature has done without
examining structure which is at the root of the problem.
Notice that reactive currents have invaded our (assumed) zero reference potential
(the ground.) This is called the common mode noise circuit. Because there was no
voltage present on the neutral, only active current, there is also reactive current present.
And, as reactive current from the load is applied across the source transformer's
impedance, reactive voltage is also quantified. In tandem, reactive current times
reactive voltage equals reactive power or "KVAR" (kilovolt-amperes reactive.) There is
how a reactive voltage potential presents itself in the grounding system of an AC circuit
-- via the neutral-to-ground connection at the AC mains. Here we are relying heavily on
the power supply's transformer for common modenoise rejection. This is essentially the
boundary where modern methods of noise suppressionend.
Well, if all of the above seems confusing, don't worry about it. The important thing
to understand is that ground wires are dirty because non-linear loads create a condition
where zero (ground) is not truly zero. But as originally stated, these are the
consequences of a chosen architecture.

Let’s back to basics and examine a restructured AC circuit where we have tossed out
the conventional hot-neutral-ground architecture and have instead adopted a balanced
circuit configuration. (Please see below Structure) Reactive currents which are the
primary source of electrical interference are now balanced at the grounding point.
6
BPSeriesUserManual
With balanced power, reactive currents null (cancel) at the center tap of the AC
transformer thereby eliminating reactive current in the ground as a source of
interference in signal circuits. Basically, hot vs. ground, and neutral vs. ground will both
read 60 volts. In other words, the hot and neutral conductors are both at 60 volts. Since
these voltages are of opposite polarity though, and given that most interference in a
typical AC line is common between the two lines, the noise in the lines is eliminated
when the two lines are added together. This is effectively known as Common Mode
Rejection (CMR).
It sounds almost too simple, but numerous testimonials bare the validity of the
balanced power theory. Balanced power has been applied in numerous audio
application environments with great success. Commonly, an additional 16dB to 20dB of
dynamic range is realized on a system-wide basis where multiple inputs and channels
are mixed. In much the same way that balanced audio lines can eliminate hum,
electromagnetic interference (EMI), and noise, the use of balanced AC power lines in
sensitive audio, video, or computer installations can make an enormous difference in
system noise and signal integrity.
So complicated production practices and relatively expensive costs, is to provide
audiophiles with a separate power supply environment, so that all equipment through
the KECES Balanced Isolation Power Conditioner to achieve its best level.

1.High Quality Toroidal Isolation Power Transformer，Feature as below：
(1)
The key to all toroidal transformer advantages is its efficiency. And the key to its
efficiency is the core. The core is a continuous strip of grain oriented silicon steel,
wound like a clock spring, under tension. It is annealed to relax the molecular
structure which ensures that all grains are in the magnetic direction (unlike the old
standard EI, with about 40% in the wrong direction). There is no air gap, resulting in
a stacking factor of 95% of its weight. Since all the windings are symmetrically
spread over the entire round, gapless core, a higher flux density is possible. The
magnetic flux is in the same direction as the grain oriented silicon steel core, thus
achieving very high electrical efficiencies. Typical efficiency figures for toroidal
transformers are 90%
(2)
Toroidal transformers radiate about 1/10 the magnetic field of EI transformers; this is,
again, because of the inherent efficiency and unique construction. The windings
which cover the core act as a shield. The magnetic field is contained doing what it
should, transforming energy from primary to secondary. This may eliminate the need
for special shielding. Likes HIFI equipment and medical equipment.

(3)
Toroidal transformers are also acoustically quieter than EI transformers. In addition the
windings tightly envelope the entire core, effectively reducing magnetostriction –the
main source of the familiar mechanical hum found in standard vertically laminated EI
transformers. Compared to EI transformers, toroidal are silent. That is why the toroidal
transformer is suitable use in sensitive equipment.
(4)
This efficiency yields the most easily identifiable feature of the toroid, its sizebenefit.
Toroidal transformers are about half the size and weight of standard transformers.

2.Surge Protection: BP-Series power conditioner protects connected equipment through
innovative series mode surge suppression that also pays attention to keeping the power
clean. Most surge suppression circuits are shunt-mode. Excessive voltage surges are
“shunted” to ground, which raises ground voltage and may contaminate audio and video
signals. KECES design absorbs surges more than 2V above peak line voltage, so
ground is not affected. KECES further innovates by using the Toroidal Isolation
transformer to replace the series inductor typically used by other brands. This ensures
extremely low stray magnetic fields within the chassis
3.Input Voltage Detection：Under Voltage Protection(UVP) / Over Voltage Protection
(OVP).
4. Isolation Ground：Since balanced power these voltages are of opposite polarity though,
and given that most interference in a typical AC line is common between the two lines,
the noise in the lines is eliminated when the two lines are added together. This is
effectively known as Common Mode Rejection (CMR).

使用說明書
一般市面上所販售的電源濾波排插，是使用電容並聯來達到雜訊濾波的功能，而對地線
的處理也只是利用外殼來做連接，其實對音響視聽設備來說，抑制雜訊的能力有限。而
牆上的壁插或傳統的電源供應器都是屬於非平衡式輸出，以下圖 AC 120V 為例，輸出電
壓一端為 120V，另一端為 OV，雖然對負載來說的確是供應 120V 的電壓，但我們知道
負載內部必定存在電容或電感，這些儲能元件所釋放出的能量(感應電流) 必須尋找自由
路徑藉以放電，倘若使用非平衡式的電源，勢必會回灌至負載端，而導線上亦有極小的
電阻，當感應電流經導線上的電阻必定會產生極小的感應電壓並透過接地線回饋到負載
端，此感應電壓即為不必要的雜訊。

為了防止非平衡式電源供應電時，負載內部的儲能元件所產生的感應電流回饋至負載端，
所以平衡設計最重要特點就是利用變壓器作為一個接地的中心，跨在負載的兩端點相差了
180 度的零電位接地，提供給負載端的所有電器設備建立在同一個零電位基準點上， 以
達到訊號最佳化。以下圖AC 120V 為例，從變壓器二次側來看，可分為+60V，ground，
-60V 三個端點。對負載來看，同樣是提供 120V AC 的電壓至負載，但是因為變壓器以平
衡式輸出為基礎，並以變壓器做為接地，因此當負載內部儲能元件所產生的感應電流開
始放電時，藉由 ground 的路徑將感應電流予以釋放，避免感應電流流入負載，因此
可
避免感應電流所產生的雜訊電壓回饋至負載。
KECES 的平衡式隔離電源處理器可有效的去除電源各種雜訊並且透過變壓器將 AC
電源重新整流後再次輸出給影音設備使用。如此繁雜的製作工法以及相對昂貴的成本，
為的就是提供給消費者獨立的的供電環境，以利所有設備透過 KECES 的平衡式隔離電源
處理器達到其該有的最佳水準。

BP 系列平衡式電源處理器特徵：
1.
使用環型隔離變壓器，特點如下：
(1).
環形變壓器的最大優點在於它的高效率。其效率的關鍵核心就是因為環形變壓器
的磁芯是透過連續性的矽鋼片捲製繞組在整
個圓周上對稱的擴展而成，所以形成了一個
沒有縫隙的磁芯能夠創造較高的磁通密 度。
有別於傳統 EI 變壓器，因為磁芯的構造導致
效率較低。（環形變壓器的效率大約
90%，
EI
變壓器的效率大約 70%）。
(2).
環形變壓器輻射出來的磁場大約是 EI 變壓器的 1/10。這是因為環新變壓器的獨
特構造和銅線繞組的方式，以利磁場的方向
能夠一至環繞在磁蕊內部，不像EI 變壓器因
矽鋼片在最外層造成嚴重的磁場干擾。這也
是為什麼環形變壓器是特別適用於敏感和精
密的電子設備，列如 HIFI 音響設備、醫療設
備…等。
(3).
環形變壓器因磁蕊是由連續性的矽鋼片繞組而成並且銅線緊密的繞組在整個磁蕊
上，有別於 EI 變壓器是由一片一片的矽鋼
片組合而成，所以環形變壓器能夠有效
的仰制電流聲也就是我們俗稱的哼聲。

(4).
因為環形變壓器有較高的效率所以在相同的規格下，體積比 EI 變壓器來得小。
