Product Description

The YDBH0.66 CT series integrates the 800/5A Current Sensor with the 40I-A CT Meter, designed for precise AC current measurement in power distribution systems. It features a single input (0.66kV rated voltage) and scalable output compatible with up to 10 external modules via RS-485 Modbus interface. Operating within 85-265V AC/DC, it supports industrial environments (-25°C to +70°C) such as manufacturing, energy management, and smart grids. The device offers ±0.5% accuracy, a compact DIN-rail design, and a 2.4-inch LCD for real-time monitoring. While optimized for non-contact detection up to 1m distance, it lacks internal battery backup. Its robust construction ensures reliability in high-electromagnetic interference conditions, making it ideal for load profiling and power quality analysis.
