Precision Isolation for AC/DC/Pulse Signals

This advanced?Closed Loop Hall Effect Voltage Sensor?delivers uncompromising accuracy for high-voltage measurement. Utilizing Hall magnetic compensation, it electrically isolates primary voltage from secondary output, eliminating insertion loss in?DC Voltage Transducer?and?AC Voltage Transducer?applications. With 20μs response time and 0–20kHz bandwidth, it outperforms traditional?Hall Effect Sensors?in dynamic signal capture.

FEATURES:

??Frequency Response?: 0–20kHz (captures 3rd-order harmonics)
??Step Response Time?: 20–200μs (enables overvoltage protection in inverters)
??Linearity Error?: <0.1% FS (5× better than basic?DC Voltage Transducers)
??Zero Insertion Loss?: Passive measurement preserves signal integrity
? Isolation Rating : Reinforced insulation per IEC 61800-5-1

Applications

Power Conversion Systems
?Solar inverter DC-link voltage monitoring
?Motor drive bus voltage sensing
?UPS battery voltage detection

High-Noise Environments
?EV charging station input protection (replaces?AC Voltage Transducers)
?Welding equipment surge detection
?Rail traction converter diagnostics

Critical Infrastructure

?Data center PDU voltage feedback
?Medical imaging equipment power supplies
?Factory automation control cabinets

Core Engineering Principles

Closed-Loop Flux Balance
Primary voltage (V<sub>N</sub>) generates magnetic flux, neutralized in real-time by Hall-controlled compensation current (I<sub>M</sub>) – achieving 0.1% linearity across?Precision Measurement Sensors.
Reinforced Isolation Barrier
4kV dielectric strength between primary/secondary circuits, critical for?Isolated Voltage Transmitters?in EV drivetrains.
Multi-Signal Compatibility
Measures DC, AC, and pulsed voltages without saturation, replacing legacy open loop hall effect current sensor solutions.

FERRTX is dedicated to setting a high bar of excellence for industries that integrate or utilize magnetics technologies in our Closed Loop Hall Effect Voltage Sensor products.
