WCS1600 100A Hall Effect Sensor, Overcurrent Protection

Description

The WCS1600 100A Hall Effect Sensor is a non-invasive AC/DC current detection module built around the Winson WCS1600 linear Hall-effect sensor IC, designed for high-current monitoring and overcurrent protection in power supplies, motor drives, battery systems, and industrial equipment. The module features a 9.0mm through-hole conductor that allows the measured wire to pass directly through without cutting or modifying the existing circuit, preserving circuit integrity and providing galvanic isolation up to 4000V . The sensor outputs an analog voltage proportional to the measured current, centered at VCC/2 when no current flows, with a sensitivity of approximately 20 mV/A . The overcurrent protection variant adds a comparator circuit with an adjustable potentiometer, allowing users to set a trip threshold between approximately 1.5A and 100A, with a resolution of roughly 3–5A . When the measured current exceeds the set threshold, a digital TTL output changes state and an indicator LED illuminates, enabling direct connection to a microcontroller, relay, or shutdown circuit. This module is suitable for individual makers building high-power protection systems and for business purchasers seeking a cost-effective, isolated current monitoring solution for equipment diagnostics and fault protection.

Features

• Non-Invasive Through-Hole Sensing: The 9.0mm conductor hole allows the measured wire to pass through without electrical connection, preserving circuit integrity and providing galvanic isolation up to 4000V .

• High Current Range: Measures DC current from 0 to ±100A and AC current up to 70A RMS, suitable for high-power motor and power supply applications .

• Adjustable Overcurrent Protection: An onboard potentiometer sets the overcurrent trip point between approximately 1.5A and 100A, with about 3–5A resolution .

• Dual Output Signals: Provides both an analog voltage output proportional to current for ADC measurement and a digital TTL-level output that changes state on overcurrent detection .

• Visual Status Indicators: Includes a signal output indicator LED and a separate overcurrent indicator LED that illuminates when the threshold is exceeded .

• Wide Supply Voltage Range: The WCS1600 IC operates from 3.0V to 12V, though module boards are typically configured for 5V DC operation .
