5A AC Overcurrent Protection Sensor Module 5V Relay

The 5A AC Overcurrent Protection Sensor Module is a highly reliable and precise solution designed to monitor AC current and protect your electrical systems from overload conditions. Featuring an onboard precision current transformer and an LM358 operational amplifier configured as a comparator, this module accurately detects AC currents up to 5A. The overcurrent threshold is easily adjustable using the onboard multi-turn potentiometer, allowing you to set custom trip points for your specific application.

Equipped with a robust 5V SRD-05VDC-SL-C relay, this module provides a direct switch output (Normally Open, Common, and Normally Closed) capable of handling loads up to 10A at 250VAC or 30VDC. This makes it ideal for standalone protection circuits, smart home automation, industrial motor protection, and DIY electronics projects. It can operate independently or interface seamlessly with microcontrollers like Arduino, ESP32, and Raspberry Pi to trigger alarms or log system events.

Features:

• Adjustable Overcurrent Threshold: Easily set the current trip point from 0.3A to 5A using the onboard multi-turn potentiometer.
• Onboard 5V Relay: Features a high-quality SRD-05VDC-SL-C relay to directly control high-power AC or DC loads.
• Precision Current Transformer: Onboard current transformer ensures safe, isolated, and highly accurate AC current sensing.
• LED Indicators: Integrated status LEDs provide clear visual feedback for power and relay actuation.
• Robust Screw Terminals: Heavy-duty screw terminals ensure secure connections for the relay switch contacts.
• Compact and Easy to Mount: Designed with pre-drilled mounting holes for quick installation in project enclosures.
