Narrowband PLC Transformer

Introduction
Narrowband PLC Transformers (also known as PLC Coupling Transformer) enable data transmission over existing power lines, eliminating dedicated wiring. These specialized Communication Transformers provide galvanic isolation (up to 1.5kVrms), noise filtering, and impedance matching for low-frequency PLC systems operating in harsh electrical environments. Designed for smart grid infrastructure, our Power Line Communication Transformers ensure reliable signal coupling across meters, sensors, and control units—even amidst voltage surges or electromagnetic interference.

Key Specifications

• Frequency Range: 9-150kHz (CENELEC A/B bands) & FCC-compliant sub-bands.

• Isolation Voltage: 1.5kVrms (60s) for human/equipment safety.

• Temperature Resilience: -40°C to +125°C operation (industrial-grade).

• Impedance Matching: Optimized for 50Ω/100Ω PLC modems.

• Insertion Loss: <0.5dB (minimizes signal attenuation).

• Common-Mode Rejection: >80dB (suppresses grid-borne noise).

Applications
Deploy these Narrowband PLC Transformers in:

• Smart Grids: AMI (smart meters), grid monitoring sensors, and fault detectors.

• Building Automation: HVAC controls, lighting systems, and security panels communicating via power lines.

• Industrial IoT: Motor drives, conveyor controllers, and remote Sensor networks in factories.

• Renewable Energy: Solar/wind inverters transmitting data through DC/AC lines.

Design Advantages

1. Superior Noise Immunity
   Triple-shielded windings and ferrite cores reject EMI from motors/relays. Pair with EMC Filter - EMI/RFI modules for full-spectrum grid noise suppression.

2. High-Voltage Safety
   Reinforced insulation withstands grid transients (IEC 61000-4-5), protecting sensitive PLC modems. Integrates seamlessly with RF Microwave Components for hybrid wireless/wired networks.

3. Compact Power Integration
   SMD designs (e.g., 12.7mm × 10.5mm) save PCB space versus discrete solutions. Co-locate with Power Inductors for stable DC/DC conversion in metering devices.

4. Long-Distance Reliability
   Low insertion loss (<0.3dB @ 100kHz) extends signal range to 1km+ on LV/MV power lines. Compatible with G3-PLC, PRIME, and IEEE 1901.2 standards.
