WCS1500 Hall Effect Base Linear Current Sensor

Galvanic Isolation Hall-Effect Design: Measures continuous AC or DC current streams via Hall-effect magnetic sensing, completely isolating high-power load lines from low-voltage microcontrollers.

Wide Current Sensing Range: Capable of precise current detection up to ±200A DC or 140A AC RMS, ideal for high-power monitoring applications.

Dual Signal Output Architecture: Delivers a proportional linear analog voltage output (A_O) for continuous current logging, alongside a adjustable digital comparator threshold output (D_O).

Onboard Over-Current Limit Adjustment: Outfitted with an integrated multi-turn potentiometer and LM393 comparator to set custom trip thresholds for instant hardware safety triggers.

Low Internal Conductor Resistance: Built with an ultra-low resistance primary conduction path to minimize power dissipation, heat generation, and voltage drop across the sensing element.

Housing & Board Material: High-grade FR-4 glass-epoxy PCB with a white insulated Hall sensor enclosure, blue trimmer potentiometer, terminal blocks, and gold/tin-plated header pins.

Technical Specifications:

Operating Voltage: 5.0V DC (± 5%).

Current Detection Range: ± 200A DC / 140A AC RMS.

Sensitivity: 11 mV/A (nominal).

Bandwidth: Up to 23 kHz.

Color: Red PCB with White Sensor Module and Blue Potentiometer.

Usage Advice: Supply 5V DC and GND to the board headers; pass the high-current conductor through the central sensing channel or primary terminal pads, and connect A_O to an ADC pin for current measurement or D_O to a GPIO pin for over-current protection.

Maintenance: Keep the central sensing aperture free of metal dust and conductive debris; clean PCB surfaces gently using a dry, static-safe microfiber cloth.

Essential High-Current Power Monitor: Position as a heavy-duty current sensor for electric vehicle motor controllers, solar battery inverter paths, industrial power supplies, and automated over-current protection circuits.

Highlight Dual Analog & Adjustable Digital Alarm Outputs: Emphasize how combined linear analog telemetry (11 mV/A) and hardware-level digital over-current threshold triggers deliver both analytics and immediate equipment safety.

Recommended Cross-Sell Add-ons: Pair with DC 5V WCS1700 Hall Current Sensor, Hall Current Sensor ACS758LCB-050B, INA226 IIC Bidirectional current sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
