Hall Effect Current Sensor HKC-KB Series Wide Temp -40 to +105°C for SMPS and Welding Power Supplies

The HKC-KB series closed-loop Hall effect current sensor uses a closed-loop (compensation) principle, providing electrical isolation between the primary and secondary circuits. It accurately measures DC, AC, or pulse currents with a measuring range of 0-4000A. The product has a supply voltage of ±12 to ±15V (±5%) and a rated output voltage of 4.0V±1%. It offers high accuracy and easy installation. Operating temperature is -20 to +85°C, and storage temperature is -40 to +105°C. It is widely used in high-current monitoring, inverters, UPS, DC motor drives, switching power supplies, and welding power supplies.
