Hall Effect Current Sensor HBC-X Series 50A Galvanic Isolation for SMPS and Variable Frequency Drives
The HBC-X 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 0-50A. The product has a supply voltage of DC ±15V±5%. The epoxy potted housing provides excellent moisture-proof, dust-proof, and insulation protection. It offers high accuracy, excellent linearity, low temperature drift, and high external interference rejection. It features optimised response time, no insertion loss, low power consumption, easy installation, and customisation support. It is widely used in inverters, UPS, photovoltaic current sensing, switching power supplies, variable frequency drives, and various new energy applications.
