Tips: Applications of the Hall effect current sensor

Application in DC automation speed control system: In this system, the Hall effect current and voltage sensor can directly replace the current transformer. It not only has a better dynamic response, but also realizes the optimal control of rotor current and overload protection for thyristor.
Application in Uninterruptible Power Supply (UPS): Controlling with a Hall effect AC current sensor can ensure the normal operation of the inverter. Send out signals with Hall effect current sensor 1 and feedback to control the trigger angle of the thyristor. Control the inverter with the signal sent out by Hall effect current sensor 2. And control the float charging power supply with Hall effect current sensor 3. Due to the quick response, Hall effect current sensor is especially suitable for uninterruptible power supply in reduction gears.
Application in electronic spot welder: Hall effect AC current sensor plays the role of measurement and control in power supply of the electronic spot welder. Its quick response can reproduce the current and voltage waveforms and feedback them to the controllable rectifier A and B, thus controlling its output. If an AC is added to the DC with a chopper, the current can be controlled more accurately. When detecting the current with Hall effect current sensor, real instantaneous value of the current can be measured while no additional loss would be introduced.
Application in power management: Hall effect AC current sensor can be installed on the distribution line for load management. Output of the Hall effect current sensor is connected with the reduction gear to monitor the electricity consumption. In case of overload, it disconnects the controlled line in time to guarantee the safety of electric equipment. Such a device can also be used for load distribution and remote control, telemetry and patrol of power network.

Existing reviews of AC Current Sensor, 5mA/100mA/1A/2A/5A to 10A

Looking for a current sensor

We are looking for a current sensor with the following specifications:
- Withstands up to 400 VDC
- Suitable for automotive applications
- Minimum IP67 rating
- Maximum temperature limit of 75℃ or higher
- DIN rail compatible package preferred
We would like to know if the following model ATO-CURTS-DJIA is available in 2A, 3A and 5A versions.

ATO Responded

Our current sensor cannot withstand temperatures of 75℃ or higher, only up to 60 degrees. None suitable for high temperatures. Model CURTS-DJIA is available in 2A, 3A and 5A versions.

Could you please help clarify the query below?

1)Whether the ATO-CUS-DC800 DC current sensor measures the current max of 4A @ 24V input line (In , In-). Please confirm.
2)Whether it withstand the 6A inrush current for 4A current measurement. Please confirm.

ATO Responded

In that case below, if the current sensor requires it withstand the 6A inrush current for 4A current measurement, we recommend the 0-10A range capacity.

High accuracy current sensor

The accuracy of 5A AC current sensor is high, and it is slightly higher than the calibration parameter. The measured data error is very small. This shipment is faster than the last time.
