Description
This 12V DC Overcurrent Protection Sensor Module is a precision safety device designed to monitor AC current and protect your equipment from electrical overloads. It utilizes an onboard current transformer to detect the magnetic field of an AC line, converting it into a measurable signal. When the current exceeds your user-defined threshold, the integrated relay triggers instantly, allowing you to cut power to the load, sound an alarm, or signal a PLC.
This module is an essential fail-safe for industrial motors, household appliances, and DIY automation projects. By providing a hardware-level cutoff, it prevents overheating, fire hazards, and expensive hardware damage caused by mechanical jams or electrical shorts.
Key Features
- Precision AC Detection: Monitors AC currents from 0A to 5A with high sensitivity and accuracy.
- Adjustable Threshold: Features a multi-turn potentiometer for fine-tuning the exact “trip point” where the relay activates.
- Isolated Protection: The current transformer provides physical isolation between the high-voltage AC line and your low-voltage DC control circuit, ensuring maximum safety.
- Switching Relay Output: Equipped with a high-quality relay (typically 10A capacity) that acts as a dry-contact switch for controlling external loads or sirens.
- Visual Status Indicators: Onboard LEDs provide immediate feedback on power status and relay activation.
- Compact Mounting: Industrial-grade PCB with pre-drilled holes for easy installation into control panels or project boxes
