[Key Features & Advantages]

✅ Ultra-low loss, highly energy-efficient

The eddy‑current loss of amorphous magnetic cores is only one‑tenth that of conventional silicon steel and one‑fifth that of ferrite, resulting in reduced heat generation at high frequencies. This leads to a 3%–8% improvement in overall equipment efficiency and greater energy savings over long‑term operation.

✅ Ultra-high precision, stable measurement

Its permeability far exceeds that of conventional materials, with excellent linearity; current‑sampling errors can be kept within ±0.5%, and it remains robust against temperature and load variations, ensuring the accuracy of metering and monitoring data.

✅ Wideband compatibility, suitable for various scenarios

The operating frequency range spans from DC to 1 MHz, offering both low-frequency high-current filtering and high-frequency EMI suppression. No additional component changes are required, enabling seamless adaptation to a wide variety of circuit applications.

✅ Compact design, easy to install

The toroidal closed magnetic circuit design eliminates magnetic leakage, while its compact winding minimizes space requirements. Compared with silicon steel components of equivalent performance, it reduces volume by more than 40%, making it well suited for PCB‑mounting in miniaturized devices.

✅ Highly durable and long-lasting reliability

The insulating protective layer is resistant to high temperatures and humidity, and the magnetic core and windings exhibit excellent stability. Its performance remains undiminished across a wide temperature range of –40°C to 125°C, enabling long-term, stable operation in demanding industrial and outdoor environments.

 

[Typical Application Areas]

  1. Smart meters / electrical energy metering devices: As precision current transformers, they provide high‑accuracy current sampling for single‑phase and three‑phase meters and serve as core components of smart grid metering systems.
  2. New energy charging piles / On-board power supplies: Used for current monitoring at the input and output terminals, overcurrent protection, and common-mode interference suppression, ensuring the safe and stable operation of charging equipment.
  3. Switching power supplies / adapters: Used as filter inductors or energy‑storage inductors to reduce ripple noise and improve power conversion efficiency, suitable for both industrial and consumer electronics power supplies.
  4. Industrial Control / Power Protection Equipment: In variable-frequency drives, inverters, and relay protection devices, it enables current signal acquisition and electromagnetic interference filtering, ensuring reliable equipment operation.
