电气连接图/Electrical connection diagram


FSD7304 使用说明/Instructions

1) 当原边电流（IP）方向沿产品打标处箭头方向流动时，VOUT为正向，反之则为负向；

When the primary current (IP) direction flows along the arrow direction of the product marking, VOUT is positive; otherwise, it is negative.

2) 错误接线可能导致传感器损坏；

Incorrect wiring may cause sensor damage.

3)当原边频率过高时，过大的容性负载可能导致传感器波形失真，具体请参考输出容性负载曲线；

When the primary side frequency is too high, excessive capacitive load may cause distortion of the sensor waveform. For details, refer to the output capacitive load curve.

4)波峰焊接最高温度 260 °C，持续时间 10 s；

The maximum temperature of wave crest welding is 260 °C, the duration is 10 s;

5) 可根据客户需求定制传感器。

Sensors can be customized according to customer needs.
