Mô-Đun Cảm Biến Dòng Điện Ac 0-5a

Giới thiệu Mô-Đun Cảm Biến Dòng Điện Ac 0-5a

Note: Module can only use DC24V power supply. The utility model has the function of anti back protection,The power indicator light is green and yellow.
Customers need to use analog signals, they can own from the B point on the module out. The corresponding relationship is 0-5V linear 0-5A current.
Because the circuit characteristics, setting the threshold value, the protection value is slightly lower than the actual value, set the current threshold for example: 2A.
Then according to the voltage and current of the corresponding table, the threshold voltage corresponding to 2V, but the reason for the circuit characteristics, the protection value should be located around 1.97V. VR2, VR3 potentiometer for factory commissioning, customers can not be adjusted. Only when the module is working for a long time after a large error can be adjusted by adjusting the two potentiometers.
The module detects the magnitude of the current in the AC circuit, preset the threshold, and when the current reaches the threshold, the relay operates on the module. It is suitable for over-current protection and alarm of all kinds of equipments.

The correction method is as follows:
1. Module power, in the case of no current detection, measuring the voltage of the B point of the module VR2, the voltage will be adjusted to 0V.
2. After the completion of the above steps, plus the current has been known to detect the VR3, such as 2A, measuring the voltage of the B point to the ground, the voltage will be adjusted to 2V by the potentiometer. Calibration complete.
For the frequent changes in the current, but also need to use the module on the end of the relay control of the customer, it is recommended in the relay output connected to AC contactor. To prevent frequen
