DC 5V WCS1500 Hall Current Sensor

Galvanic Isolation Hall-Effect Architecture: Uses non-contact Hall-effect magnetic sensing to sample high-current DC/AC paths while isolating sensitive downstream microcontrollers.

Wide Current Sensing Bandwidth: Capable of measuring currents up to ± 200A DC or 140A AC RMS, providing broad diagnostic coverage for high-power circuits.

Dual Signal Output System: Delivers a proportional linear analog voltage output (A_O) for continuous telemetry alongside an adjustable digital over-current threshold output (D_O).

Onboard Hardware Over-Current Trigger: Equipped with an onboard LM393 comparator and multi-turn precision potentiometer to set instant hardware safety shutdown thresholds.

Low Thermal Conductor Loss: Designed with a low-resistance primary current path to reduce power dissipation and prevent thermal buildup under heavy load conditions.

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

Technical Specifications:

Operating Supply Voltage: 5.0V DC (±5%).

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

Analog Sensitivity: 11 mV/A (nominal).

Color: Black PCB with White Hall Sensor Enclosure and Blue Potentiometer.

Usage Advice: Supply 5V DC to VCC/GND; pass the target load line through the central sensing channel, and connect A_O to an analog ADC pin for current logging or D_O to a GPIO pin for over-current protection.

Maintenance: Keep the central sensing aperture free of metallic dust or conductive debris; wipe PCB surfaces gently using a soft, dry microfiber cloth.

Essential High-Current Safeguard Module: Position as a heavy-duty current sensor for electric vehicle motor controllers, solar inverter battery banks, industrial power supplies, and automated power monitoring.

Highlight Dual Telemetry and Instant Hardware Trip: Emphasize how combined linear analog current sensing (11 mV/A) and hardware-level digital over-current switching deliver both detailed analytics and immediate equipment safety.

Recommended Cross-Sell Add-ons: Pair with WCS1500 Hall Effect Base Linear Current Sensor, DC 5V WCS1700 Hall Current Sensor, INA226 IIC Bidirectional current sensor, and ESD antistatic mat 50x40CM PCB Welding Mat.
