3 Commercial devices: Office equipment (printers, copiers), telecom base station auxiliary modules, server power monitoring

4 Measurement tools: Low-power current testing instruments, circuit debugging and diagnostic setups

5 Information technology equipment: Data center power module monitoring, network device power supply management

注意事项 PRECAUTIONS

1 Power supply: Do not reverse the power supply polarity (Vcc and GND) to avoid sensor damage

2 ESD protection: Handle with anti-static measures to prevent electrostatic discharge damage

3 Installation: Ensure the primary conductor fully fills the through-hole for accurate measurement; use twisted cables to reduce noise interference

4 Environment: Avoid using in high radiation areas, direct sunlight, corrosive gas environments (e.g., H2S, NH3, SO2), or places with strong static electricity

5 Cleaning: Do not use water or water-soluble detergents for flux cleaning; do not seal with resin or coat with water

6 Application restrictions: Not suitable for high-safety or life-critical applications, including systems where failure could result in personal injury or loss of life.

7 Storage: Avoid long-term storage in high-temperature (over 40°C) and high-humidity (over 85%) environments

8 Open-loop usage: For high-frequency applications, ensure the magnetic core does not overheat; exceeding rated current may lead to non-proportional output
