±300A Current Measurement
The HC-SN300V4B15 has a nominal current rating of ±300A. Kohshin specifies a linearity range extending from zero to approximately ±450A and a saturation-current rating of ±700A.
±4V Analog Output
The V4 designation indicates a voltage-output version. At rated current, the sensor provides a nominal ±4V output with a specified load resistance of 10kΩ.
±15V Dual Power Supply
The B15 suffix identifies the dual-supply version designed for a ±15V control power supply. Kohshin specifies a ±5% supply tolerance for this configuration.
Fast Current Monitoring
With a specified response time of 10µs or less under the manufacturer's test conditions, the sensor is suitable for current feedback and monitoring in industrial power-conversion equipment.
