APPLICATIONDK-25VA-10000VABK(JBK) "Control transformer" is our
company after many years to further absorb the advantages of
similar products at home and abroad, the use of advanced technology
and rigorous design for manufacturing, power can do 25VA-100KVA.
Preferably foreign advanced method of terminal terminals, with
excellent performance, reliable work, low energy consumption, small
size, wiring safety, high protection level, wide application and
other characteristics, can work for a long time under rated load,
is an ideal voltage power supply. The "single-phase isolation
transformer" in the BEK series not only has the function of voltage
change in the power grid, but also can isolate the third harmonics
of the power grid to the equipment, and the establishment of a new
neutral line point can remove the interference of the power grid
Chinese mode and other neutral lines, because the output end of the
single-phase isolation transformer is completely "disconnected"
from the input end. This effectively plays a good filtering role on
the input end of the transformer (power supply voltage supplied by
the grid), thus providing a pure power supply voltage to the
electrical equipment. (If additional shielding can be further
exempted from the high-frequency pulse interference and noise
caused by the transformer internal karma, the company can design
and produce high-quality isolation transformers for customers)
Materials: 1. Iron core The use of high-quality new cold to
oriented high silicon silicon steel sheet stacked, adding silicon
to the steel sheet can reduce the conductivity of the steel sheet,
increase the positive rate, it can reduce eddy current, reduce its
loss, the quality of the transformer used in the quality of the
silicon steel sheet has a great relationship; 2. Wire Using PEW,
UEW, BIW, SEIW, FEAI light covered wire and glass wire, the
transformer for the wire requirements are good conductivity, the
coating layer has enough heat resistance, and to have a certain
corrosion resistance, the most commonly used temperature grade F
enameled wire. 3, insulation materials The high temperature
resistant insulating paper is used as the insulating material, with
high temperature insulation, flame retardant and moisture
resistance. 4. Terminal block Small power using terminal block,
beautiful appearance, excellent pressure, temperature resistance,
flame retardant performance. High power adopts high quality copper
bar. 5. Iron feet Using CNC bending cold binding plate, there are
colorful plating (golden), blue zinc (silver), zinc (ivory),
surface anodized "black" and other environmental protection plating
options.SPECIFICATIONS 1, Product name: Control
