SMD Drive Transformer, Broadband PLC transformer

‌Broadband Power Line Communication (PLC) Transformer Characteristics‌

1. ‌Low Insertion Loss‌
   Optimized for narrowband (NB) applications, featuring specially designed magnetic core materials and winding configurations to minimize signal attenuation, ensuring efficient high-frequency transmission (e.g., 150kHz–20MHz) over power lines.

2. ‌EMI Suppression & Isolation‌
   Electrically isolated design reduces electromagnetic interference (EMI) while effectively filtering power line noise (e.g., switching noise, impulse noise), improving signal-to-noise ratio (SNR).

3. ‌Wideband Compatibility‌
   Supports high-frequency carriers (e.g., >2MHz) with impedance-matched circuitry to mitigate multipath transmission and reflections, adapting to diverse line conditions (e.g., high-voltage grids or 400V residential lines).

4. ‌Integrated Protection‌
   Some models incorporate overvoltage protection (e.g., with GMOV devices) to safeguard against lightning surges or transient voltage spikes, enhancing system reliability.

5. ‌Standardized Compliance‌
   Aligns with international standards (e.g., IEEE 1901.2), enabling seamless integration into smart grid systems, smart meters, and other applications with narrowband data rates up to 500 Kbps.

‌Key Applications:‌

• Smart metering
• Home energy management
• Industrial IoT over power lines
• Grid monitoring and automation

‌Note:‌

• Core materials typically include ferrite or nanocrystalline alloys for high-frequency performance.
• Winding techniques (e.g., bifilar or Litz wire) minimize skin effect losses.
