High Quality Toroidal Isolation Power Transformer,Feature as below
A.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%.

B.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.

C.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.

D.This efficiency yields the most easily identifiable feature of the toroid, its size benefit. Toroidal transformers are about half the size and weight of standard transformers.

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.

Input Voltage Detection:Under Voltage Protection(UVP)、Over Voltage Protection(OVP).

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).

Clean balanced power for a modest audio/video set
The most important part is a huge custom made toroidal transformer, which provides a true balanced and isolated voltage, free of DC-offset, consisting of 2 voltages of 115 Volts, out of phase. The benefit of true balanced voltage is that it has a high degree of distortion rejection. Thus, all mains-related equipment are able to work better. Both shielded and unshielded power cords hardly emit any electrical fields, and all mains filters (serial or parallel) work much more efficient with balanced power!

A very large toroidal transformer is housed inside the unit. This type of transformers have several benefits over ordinary (block) transformers, for instance, the efficiency is better (typically less heat dissipating), size is smaller, and weight is only half that of an ordinary transformer having the same power. And, very important to us, the radiation field of toroidal transformers is just approximately 10 % of that of the block transformer.

To obtain a really good transformer, the quality of the core material is very important. This material greatly determines, how good the energy-storage and filtering is. Even the way, the wire is wound onto the core is decisive, as it determines the noise rejection and output symmetry. In the transformer, between the primary and secondary windings, there's a static shield, which prevents noise coming through to the output due to capacitive coupling.

The BP-1200 has an inrush current limiter incorporated, so your domestic fuse won't blow upon powering it up. The BP-Series power conditioner also incorporates a surge protection, it 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 2 V above peak line voltage, so ground is not affected. KECES further innovates by using their own custom toroidal isolation transformer. This ensures extremely low stray magnetic fields within the chassis. It completely replaces the series inductors (filters) typically used by other brands.

Since with balanced power the two voltages are of opposite polarity, 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 widely known as Common Mode Rejection (CMR).

The dynamic range of any A/V set will be limited by the amount of noise on the mains. All equipment in the chain is sensitive to this noise. The weakest link in your A/V chain determines the maximum performance of the entire A/V set. That's why we advise you to connect all your equipment to the BP-1200. This way, you'll have the maximum performance of your A/V set.

Sonically the most important benefit of the BP-1200 is a cleaner and more powerful sound and picture. In addition, sound will be more tranquil and the soundstage will be deeper.The transformer used, adds extra power to your sound due to the inductive energy storage and very low impedance. This causes kettledrums and bass guitars to sound more realistic than ever. Bass response goes down to very low fundamentals, is more taut and better defined, in addition, the harmonic range widens, the soundstage becomes less clogged, and sounds more dynamically.
