• Common mode choke cores

    Characteristics:

    Common-mode inductor is also called common-mode choke coil, is essentially a two-way filter: on one hand, to filter electromagnetic interference in signal lines; on the other hand, to restrain itself from sending out electromagnetic interference and to avoid affecting the normal work of the other electronic equipment under the same electromagnetic environment. Common-mode inductor also plays a role as EMI filter to suppress electromagnetic waves outward radiation which produced by high speed signal lines.

  • Linear transformer magnetic cores

    Characteristics:

    In modern measurement filed, linear transformer are widely used especially known as Hall sensor. The advantages of Hall sensor are as follows: the output signal is good, a large range of testing. The drawbacks are high degree of distortion and low test frequency (usually less than 20khz). The error of nanocrystalline linear transformer is smaller than Hall current sensor. The usage frequency of linear transformer can be 100KHz which is 5 times than Hall sensor. Linear transformer has a considerable advantage in precision measurement system.

  • DC resistance current transformer cores

    Characteristics:

    When using current transformers, the accuracy of measurement determined by the primary current amplitude error (contrast) and phase error (difference). In medium accuracy without the requirement of DC component of electric meter, the absolute value of these two is very low, but it can be compensated through the relevant correction circuit. DC component of current transformer is different, because the difference of its  phase difference is large and stable. The special characteristic of amplitude error is relatively small. There is an energy measurement error. The error changes with the primary current. If the phase difference don't compensate, it cannot be applied in high perceptual load.

  • High-frequency transformer nanocrystalline cores

    Characteristics:

    Transformer is irreplaceable in the power supply system. It has the following main functions: Electrical isolation;To realize the voltage rise or fall by different variety; High power rectifier vice edge phase shift is different, beneficial ripple coefficient decreased; Magnetic coupling transmit energy; Measure the voltage and electricity. Selection of nanocrystalline materials makes the transformer smaller volume, lower temperature and higher efficiency at the same time. Under 50 KHZ high-power switching power supply, nanocrystalline is the optimal choice of material of transformer.

  • Precision transformer magnetic cores

    Characteristics:

    The Bs of Nanocrystalline alloy is between Silicon steel and permalloy. The lower the Bs value, the more beneficial to reduce instrument security factor. When the system fails and generates a large current through the current transformer,a cores more easily saturated, the secondary current does not increase proportionally, therefore protecting the instruments. The permeability of nanocrystalline alloy is near to permalloy but higher than silicon steel,so it’s suitable for producing high-precision transformer magnetic cores. Because of the density and lamination factor of nanocrystalline alloy are lower than permalloy. With the same size and similar performance of these two cores, nanocrystalline cores is lighter 1/4 or more than permalloy and a lower manufacturing cost can be about 1/3. Furthermore, nanocrystalline alloy has a wider linear range than permalloy.

  • ELE RCD and ELM RCD cores

    Characteristics:

    The main differences between Type A leakage protector and AC type leakage protector are as follows: AC type leakage protector can only effect on AC leakage but not for pulsating DC leakage while the A type leakage protector can effect on both AC leakage and pulsating DC leakage. In addition, AC type protector can only detect leakage situation of a standard sine wave of the grid, it is suitable for using in some areas with better conditions; but in some areas where the grid condition is not good enough, we use the AC sine wave mixed into some odd wave. A type leakage protector can detect hybrid waves, particularly in the use of DC harmonic spaces, but AC type leakage protector saturate easily and no output performance.Thus, A type leakage protector is more comprehensive protection against leakage than AC type.

  • Coating cores

    Characteristics:

    Electrostatic powder coating called "electrostatic spray".Electrostatic powder coating is coated by particles. It produced by coating machine . Then on the charge, electric field formed between the electrode and the coated objects. Using the electrostatic adsorption to coat the objects.Main features: spray material is 100% solid powder, high degree of automation, less microporous coating, good corrosion resistance, and a thick film coating can be performed. Coating technology can be applied to various types of cores which wraps fine lines. For the thick line and large external application areas, the core had better to be covered by shell.

  • PFC Inductance cores

    Characteristics:

    When switching power supply using a large capacitor filter, the input power factor is between 0.5~0.7. However, domestic and international standards ask that the input power factor of switching power supply has to achieve more than 0.9, which means the power factor correction circuit must be used to improve the power factor. Compared with 0.1mm thick silicon steel cores, the Fe-based amorphous alloy core for PFC inductor in 20KHz 2.5KVA power factor correction circuit, making the iron loss from 28.8 W down to 4.4W and the weight reduces from 4.75kg to 4.2kg .Nanocrystalline’s flexible production size and lower lost make it the ideal material for PFC inductor, especially for high - frequency switching power supply.
