BL1Y2-200IOV2L

The BL1Y2-200IOV2L is a BYD Semiconductor current sensor module that uses a magnetic, Hall-effect principle to measure AC or DC current without a shunt, aimed at electric-vehicle and industrial power systems. Because the measurement is contactless, the sensor isolates the high-power path from the measurement circuit, removes the insertion loss of a shunt and stays accurate over temperature, and there is no wear part, so the sensor is stable over a long service life. The 200 class current range suits the measurement of a motor phase current or a battery current in a traction or a power system, and the automotive grade covers the temperature and the vibration of an under-hood environment. It provides an analog output proportional to the current for an ADC to read, in a robust module that pairs naturally with a BYD power module and MCU. Typical applications include the phase current of a motor drive, the charge and discharge current of a battery, the output current of a converter and the current monitoring of a charging system. Every sensor BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the current range, the isolation and the mounting and plan the accuracy over temperature.
