TRIPLE-SHIELDING
Technology
Thanks to its advanced triple shielding technology, it can effectively eliminate
any interference that might affect sound quality. Electrostatic shielding
prevents high-frequency noise, electromagnetic shielding blocks environmental
EMI.Magnetic shielding further isolates the transformer, reducing its
magnetic leakage by 80% and preventing any disturbance that could affect
delicate audio signals, eliminating noise or hum in high-end devices.
They deliver flawless power for circuits, aligning with stringent EMC standards
to eliminate any possible interference and contamination at the source.
PERFECT
Design Structure
Crafted for perfection, it features a high-permeability, low-core-loss quality
toroidal core, premium Oxygen-free copper coils, an epoxy potting and pin
design. This trio ensures power stability, working efficiency, and exceptional
voltage regulation capabilities, offering the ultimate audio fidelity
experience-pure, dynamic, and superior.
Boasting superior triple-shielding technology and a perfectly designed
structure pushed to the limits.
Characteristic 1
The fully enclosed printed circuit board is directly welded and installed with beautiful appearance
Characteristic 2
Small installation height, compact structure, solid, earthquake-resistant, moisture-proof, flame-retardant, and high electrical strength
Characteristic 3
It has the functions of magnetic shielding, electrostatic shielding and electromagnetic shielding, which can significantly suppress common mode interference, reduce electromagnetic interference and reduce magnetic flux leakage generated during work
Characteristic 4
Using high-quality silicon steel ring-shaped iron core, it has high efficiency, small magnetic leakage, low noise and small no-load current
Characteristic 5
Built-in temperature protector, low temperature rise, safer to use
Characteristic 6
Triple shielding, suitable for high-precision equipment power supply applications
