Description
The WCS1800 is a high-precision Hall-effect current sensor designed for detecting both AC and DC currents up to 35A. It offers dual output modes, an analog voltage signal for real-time continuous monitoring and a digital switch output that triggers when a preset current threshold is crossed. This makes it ideal for intelligent control systems, overcurrent protection, and energy-efficient designs.
Key Features
