WCS1700 60A Hall Effect Sensor, Overcurrent Protection

Description

The WCS1700 60A Hall Effect Sensor is a non-invasive AC/DC current detection module built around the Winson WCS1700 linear Hall-effect sensor IC, designed for mid-range 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 33 mV/A . The overcurrent protection variant adds a comparator circuit with an adjustable potentiometer, allowing users to set a trip threshold across a usable range of roughly 1A to 60A . 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. With its balanced combination of range and resolution, the WCS1700 is well-suited for individual makers building motor stall protection or short-circuit detection 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 .

• Balanced Current Range: Measures DC current from 0 to ±60A and AC current up to 40A RMS, offering better resolution than higher-current WCS variants for mid-power applications .

• Adjustable Overcurrent Protection: An onboard potentiometer sets the overcurrent trip point across a usable range of roughly 1A to 60A .

• 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 power indicator LED and a separate overcurrent indicator LED that illuminates when the threshold is exceeded.

• Wide Supply Voltage Range: The WCS1700 IC operates from 3.0V to 12V, though module boards are typically configured for 5V DC operation .
