2.Product Features
a. The high-efficiency iron core has no air gap, and the stacking
factor can be as high as 95%.
b. Less vibration noise:The iron core has no air gap, which can
reduce the noise of the induced vibration of the iron core. The
windings evenly and tightly wrap the annular iron core, which
effectively reduces the "hum" sound caused by magnetostriction.
c. Low operating temperature:Because the iron loss can reach
1.1W/kg, the iron loss is very small, the temperature rise of the
iron core is low, and the winding has a good heat dissipation on
the iron core with a lower temperature, so the temperature rise of
the transformer is low.
d. Easy to install :The toroidal transformer has only one mounting
screw in the center, which is especially easy to quickly install
and disassemble in electronic equipment.
3.Application
a. Audio equipment
Among the toroidal transformer products of this factory, there are
first and foremost products that are well-known in audio equipment.
Such as high-performance products that can be used as power
transformers in Class 3 high-power hi-fi amplifiers and power
transformers for medium and small power audio equipment.
High-quality toroidal transformers can be used for power ranges
from 6VA to 1000VA.
b. Electrical control
Such as for current and voltage transformers. High precision, high
stability transformer made by toroidal transformer process. New
high-performance magnetic materials such as permalloy soft magnetic
materials, amorphous materials or nanocrystalline alloys can be
used as magnetic cores, with precise intelligent instruments and
special testing methods. It can ensure accurate transformer
parameters and completely consistent performance.
