The Hall Effect Sensor Module can be used to detect the presence of an magnetic field. If there is an magnetic field present, it will report a high level signal.
The YX850 Power Failure Automatic Switching Standby Battery Lithium Battery Module DC5V-48V Emergency Converter. It is an automatic switching module. When the battery is dead or there is a problem with the battery, it is powered by the power supply.
The IRFB9N60A is a 600V 9.2A Third Generation HEXFETs from International Rectifier provide the designer with the best combination of fast switching, ruggedized device design, low on-resistance and cost-effectiveness.
The IRFB4110PBF is a 100V single N-channel HEXFET® Power MOSFET with extremely low on-resistance per silicon area and fast switching performance using Trench MOSFET technology.
The CD4049BM and CD4050BM devices are inverting and noninverting hex buffers, and feature logic-level conversion using only one supply voltage (VCC) Inverting Hex Buffer IC SOP-16 Pins Package.
The HW586 is maximum battery capacity range: 9999Ah (1Ah = 1000mAh) greater value by shifting the decimal point to switch, when the display is less than 10Ah X.XXX, as shown above to achieve 10Ah XX.XX, and so on.
