Toroid cores for switching power supply made of nanocrystalline are featured by its high magnetic permeability and low loss. It's the ideal material for many components in single-ended, push-pull or bridge type high frequency switching power supply, such as main transformer, magnetic amplifier, choking coil, stored inductance, filtering inductance, common mode choke and spike blocker.
Application:
Main transformer, pulse transformer, control transformer, etc in medium and small power switching power supply modules. Applicable in different kinds of work mode, like single-ended, bridge type, push-pull, etc.
Properties:
High magnetic permeability and low coercivity
Low loss, low temperature rise
A flexible selection of cores with different magnetic performances according to the work mode of switching power supply.
The initial magnetic permeability and temperature stability between nanocrystalline soft magnet alloy and permalloy are similar. Under the same conditions of core sizes and characteristics, the weight of the former is much lighter
(about 1/3 lighter), cost much lower.
Applications:
Electronic kwh meter
Precise power meter
Overcurrent protection in mechanical control apparatus
Current control in industrial automation
Amorphous Metal transformer core Performance Advantages & Feature
miniaturizing and lightening of the transformers, decreasing the direct cost, assemble easily and quickly, greatly improved the production capacity and reduce the noise at the same time.
R Raw material: Zhongyue Amorphous J1K101 iron based amorphous ribbon(width:120 mm, 140 mm,170 mm,213mmï¼?
R Flux density: 1.25~1.35 Tesla
R Material density: 7.18 g/cm³
R Low excitation--decrease no-load current, and noise
Application
Current transformers can convert large currents into small currents in a certain proportion, thereby providing current for various instruments and relay protection, and isolating the secondary system from high voltage. This way can protect workers and equipment, can also simplifies and standardizes the manufacture of meters and relays.
Advantagesï¼?
In order to improve the current transformer precision, has to improve the magnetic permeability of current transformer cores. Compared with silicon steel core, nanocrystalline core has better magnetic permeability. Compared with permalloy core, the cost of nano core is lower. So nano core is the ideal material of current transformer. It is widely used in precision current transformer, zero sequence current transformer, medium and high frequency transformer.

The EP/LP core range was specially
designed for wideband transformer
applications where low build height is a
must. The board area occupied by the
assembly is almost a square, allowing
high packing densities on the PCB.
The bobbins have two rows of pins
allowing easy design of multiple output
transformers.
Cores are available in high permeability
materials, including the new low
THD material 3E55, for wide band
transformers and in power materials for
small power transformers.
The Iron Based Amorphous Ribbon is made by the composition of 80%Fe, 20%Sic and B-metal elements materials and formed by strip-casting technology.
With high permeability, low loss and ideal stability, it can meet modern electronic product's requirements in high frequency, large current, small size and energy saving, and can also replace silicon steel, perm alloy and ferrite in electricity utility and electronic products.
Performance Advantages & Feature
R High saturation flux density-- to reduce winding turns, minimize product size
R High resistivity, low coercivity--to improve production performance
R Low loss(1/3 to 1/5 of silicon sheet)--to cool temperature, improve efficiency
R Low excitation--decrease no-load current, and noise
R Adjustable permeability--adopt different heat treatment process according to different requirement
R High temperature stability--long-term operation under 130° C
PM cores are a variation on classic P cores, suitable for large high power transformers and energy storage chokes. They have larger wire slots facilitating easy assembly, but still the good shielding of a closed core shape.
PM cores can be found in transmission and radar equipment and in various high power industrial installations.
