Hall voltage transducer

Hall voltage transmitters are key interfaces for safe voltage monitoring in power systems and substations. They provide high isolation while accurately converting kilovolt-level AC or DC voltages into standard low-voltage analog signals.

These standardized outputs can be directly fed into SCADA or Distributed Control Systems (DCS) for real-time remote monitoring, data acquisition, and fault diagnosis of power buses, high-voltage DC transmission systems, and renewable energy plants.

In EV fast chargers and large Energy Storage Systems (ESS), Hall voltage transmitters safely and reliably monitor high-voltage DC bus voltages. Operating typically between 500V and 1500V, these transmitters provide strong electrical isolation to protect low-voltage control circuits and personnel.

They deliver accurate voltage data to control units for efficient power management, fault protection, and precise energy metering.

In industrial applications, Hall voltage transmitters are essential protection and feedback components in high-power inverters, converters, and DC/DC systems. They continuously monitor the DC-Link voltage on the inverter’s DC side and quickly provide isolated, accurate voltage feedback to the main controller or PLC.

This fast, isolated signal is critical for precise voltage closed-loop control and serves as the basis for overvoltage and undervoltage protection, safeguarding expensive power devices from damage.
