Hall voltage sensor

Hall voltage sensors are essential safety and control components in New Energy Vehicles (NEVs) and large Energy Storage Systems (ESS). They provide precise, isolated monitoring of high-voltage DC (HVDC) bus voltages, safely converting kilovolt-level signals into low-voltage outputs for control units.

These sensors are critical for overvoltage protection in Battery Management Systems (BMS) and for accurate system power calculation, ensuring safe and stable operation of high-voltage systems.

In rail transit (high-speed rail, metro) and large industrial DC power systems, Hall voltage sensors are a primary solution for power measurement. On traction substations and locomotives, they provide isolated and precise monitoring of overhead line voltages or DC intermediate circuit voltages.

With wide bandwidth capabilities, they can measure stable DC voltages and accurately capture voltage fluctuations, transient spikes, and harmonic distortion, delivering reliable data to ensure the safety and efficiency of traction systems.

Hall voltage sensors excel in dynamic response and wide measurement bandwidth, making them ideal for power quality analysis and high-frequency power applications. They monitor complex AC waveforms, transient voltages, and higher-order harmonics, serving as critical components in high-end power analyzers and inverter/rectifier control circuits.

By providing real-time, high-fidelity voltage feedback, these sensors enable precise system control and fault diagnosis, effectively improving power output quality and stability.
