Principle Feature

The principles of Hall Voltage Sensor is the same as the closed loop hall current sensor, but need to convert the voltage of the primary terminal to current through the resistor R1.So the hall voltage sensor is also used to test current signal, and the output compensation current/offset current can accurately reflect the changes of primary voltage signal. To select the right R1 value, please choose different sensors based on the test voltage and power.

Feature

● Closed- loop (compensated) voltage transducer
● Supply voltage: DC ±12–15V
● Capable measurement of DC and AC voltage with galvanic isolation between primary circuit and secondary circuit.

Advantages

● High accuracy
● Very good linearity
● Easy installation
● Low temperature drift
● High immunity to external interference
● Can be customized

Application

● Locomotive application

● AC/DC variable-speed drive

● Electric power grid

● Switched Mode Power Supplies (SMPS)

Application of Hall Effect Current Sensors in Rail Transit

In the traction system of a locomotive or EMU, high-precision voltage and current sensors are used to measure the voltage and current signals at the grid end and the traction motor end. High-precision sensors convert high-voltage signals or high-current signals into weak current analog signals to facilitate the identification of back-end acquisition equipment.

Application of Hall Effect Current Sensors in UPS power supply system

In the UPS power system, the closed-loop Hall effect current sensor is used to measure the output current, and the UPS controller performs feedback control based on this current to ensure the normal operation of the inverter power supply. Due to its fast response time, it is particularly suitable for uninterruptible power supplies in computers.

Application of Hall Effect Current Sensors in photovoltaic new energy system

Hall effect current sensors play an important role in monitoring and controlling photovoltaic power generation systems. In photovoltaic power generation systems, the magnitude and flow direction of current are important indicators for monitoring and control. Hall effect current sensors can measure and monitor the output current of photovoltaic panels with high precision, and transmit these current signals to the inverter. The inverter controls and adjusts based on these signals to ensure the stability of the photovoltaic power generation system and efficiency.

Application of Hall Effect Current Sensors in electric welding machines

In the welding machine power supply, the Hall effect current sensor plays a measurement and control role. Its fast response can reproduce current and voltage waveforms and feed them back to controllable rectifiers A and B to control their output. Using a chopper to superimpose DC with AC can control the current more accurately. Using Hall effect current sensors for current detection can measure the true instantaneous value of the current without introducing losses.

Application of Hall Effect Current Sensors in new energy vehicles

A current sensor is a device that converts a current signal into another analyzable signal. In the field of electric vehicles, the main application scenarios of current sensors include: BMS current monitoring, current monitoring on motor controllers, PDU current monitoring, OBC, DC/DC current monitoring, leakage current detection of charging piles, etc.

During the battery charging and discharging process, the automotive battery management system can use hall effect current sensors to collect the charging and discharging current of each battery in the electric vehicle's power battery pack in real time to prevent the battery from overcharging or overdischarging. In addition, relying on the hall effect current sensor, the battery management system can also detect the battery power consumption and provide the battery status in a timely manner, effectively preventing battery leakage, insulation damage and local short circuits, and then selecting the correct battery status.

Problems with the battery ensure the reliability and efficiency of the entire battery pack.
