Hall sensors can achieve non-contact measurement, with fast response, reliable and flexible, compact size and excellent heat dissipation performance. Applying Hall sensors to ammeters to achieve non-contact current detection not only improves safety, but also avoids measurement errors caused by contact resistance or poor contact. Compared with traditional shunts, Hall sensors insertion loss and electrical isolation, can more accurately reflect the actual value of the measured current, and have high measurement accuracy. Hall sensors are not affected by inductance, can truly transmit the waveform of the measured current, and are more accurate in measuring high-frequency and large currents. Greatly improve the stability and safety of flight control power supply, and provide high- data support for equipment operation. Wide voltage input and wide voltage detection, the power module supports 7 to 100 volt wide voltage input and 7 to 100 volt wide voltage detection, providing reliable protection for flight safety., Manufacturer: Ounfhtrttk
