1 INTRODUCTION

1.1 Product Features

Wide Voltage Input Wide Voltage Detection

The power module supports wide voltage input from 7 to 100 volts and wide voltage detection from 7 to 100 volts, providing reliable protection for flight safety.

Hall-Sensor Ammeter Non-Contact Detection High-Precision Measurement

SIYI Technology’s innovative design applies Hall sensors to ammeters to achieve non-contact current detection, which not only improves safety but also avoids measurement errors caused by contact resistance or poor contact. Compared with traditional shunts, Hall sensors eliminate 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.

Compact & Lightweight Excellent Heat Dissipation Performance

Born for the smart robotic ecosystem, minimalist design, small as millimeters, light as millet. All-aluminum alloy structure, high heat transfer coefficient and uniform heat dissipation.
