KQ-130F Power Cable Carrier Module

Power Line Communication (PLC) Technology: Transmits and receives digital data directly across existing AC or DC power cables, eliminating the need for dedicated communication wiring.

High-Anti-Interference Carrier Modulation: Utilizes robust carrier modulation/demodulation circuitry designed to reliably penetrate power line noise and grid harmonics.

Standard UART Serial Interface: Features a simple TTL-level UART interface (TXD, RXD) that connects directly to microcontrollers, Arduino, ESP32, or industrial controllers.

Transparent Data Transmission: Operates as a transparent serial link, allowing data frames to pass seamlessly across power lines without requiring complex protocol wrapping.

Integrated Primary Isolation Transformer: Built with an onboard high-frequency coupling transformer that electrically isolates control signals from high-voltage AC power lines.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with onboard power carrier IC, coupling transformer, filtering inductors, capacitors, and gold/tin-plated SIP header pins.

Technical Specifications:

Carrier Frequency: 122 kHz.

Operating Supply Voltage (V_CC): 5.0V DC ( ± 5%).

Communication Interface: TTL UART Serial (9600 bps default).

Target Power Line Voltage: Up to 220V AC / 300V DC.

Color: Green PCB with Black Transformer/Components and Silver Pins.

Usage Advice: Connect 5V, GND, TXD, and RXD to your host microcontroller; route the AC/DC power line coupling pins (L/N) through appropriate safety fuse protection directly to the target power conductors.

Maintenance: Handle with proper ESD precautions; keep the PCB clean, dry, and free of moisture, dust, or flux residue.

Essential Power Line Communication Module: Position as an ideal solution for smart street lighting controls, solar panel telemetry, home automation over existing AC wiring, and long-range industrial data links.

Highlight Wire-Free Telemetry Advantage: Emphasize how PLC technology turns existing power infrastructure into a communication network, saving significant labor and cable deployment costs.

Recommended Cross-Sell Add-ons: Pair with PZEM-004T AC Electric Energy Metering Monitor, AC Single Phase Voltage Transformer Sensor, 5A Single-Phase AC Current Sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
