Main Advantages

  • Compact & High-Density Integration
    Featuring direct insertion pins with 2.54–5.08 mm spacing for seamless PCB soldering. Dimensions are only 15 × 10 × 8 mm, weighing under 5 g, making it ideal for space-constrained, high-density circuit layouts.
  • High Precision & Low Phase Error
    Combines a silicon steel/nanocrystalline composite core with precision winding technology, achieving an accuracy class of 0.5 and secondary-side phase error below 0.5°, suitable for high-precision applications such as energy metering.
  • Wide Bandwidth & Fast Dynamic Response
    Supports a frequency range of 50 Hz–20 kHz with a response time under 5 ms, capable of accurately tracking rapid current transients in inverter and converter outputs.
  • High Reliability & Excellent Noise Immunity
    Fully encapsulated in epoxy resin with isolation voltage ≥ 3 kV, operating temperature range of –40 ℃ to +105 ℃, and EMC immunity meeting Class A/B industrial standards.
