错误的接线可能导致传感器损坏.传感器通电后,当被测电流从传感器箭头方向穿过,即可在输出端测得同相电流值. Incorrect wiring may cause damage to the sensor. After the sensor is powered on, when the measured current passes through the arrow direction of the sensor, the in-phase current value can be measured at the output end 当输入电流排完全充满原边穿孔时动态特性最佳(di/dt 和响应时间). the best dynamic characteristics (di/dt and response time) when the input current bar is completely full of the primary side perforation. 测量电阻是指工作电源在±15V,测量直流电流时.若测量交流电流时,测量电阻降低到 70%. the measurement resistance refers to the working power supply at ±15V, measuring DC current. If the AC current is measured, the measurement resistance is reduced to 70%. 工作电源在±12V,测量直流电流时,测量电阻降低到 75%.若测量交流电流时,测量电阻再降低到 70%. the working power supply is ±12V, the measurement resistance is reduced to 75% when the DC current is measured. If the AC current is measured, the measurement resistance is reduced to 70%. |
