A250 type active transient current transformerDetailed product description：

Technical characteristics and related parameters of A250 active transient current transformer:
Characteristics:

The A250 active transient current transformer does not contain ferromagnetic materials, has no hysteresis effect, and has almost zero phase error; There is no magnetic saturation phenomenon, so the measurement range can range from several amperes to several hundred kiloamperes of current; The structure is simple and there is no direct circuit connection between it and the measured current; The response bandwidth is 0.1HZ-1MHz. Compared with traditional transformers with iron cores, it has a wide measurement range, high accuracy, stability and reliability, response frequency bandwidth, as well as measurement and relay protection functions. It is small in size, light in weight, safe, and meets environmental protection requirements. Due to the characteristics of real-time current measurement, fast response speed, no saturation, and almost no phase error, this type of current transformer can be applied in situations where signal distortion is severe, such as relay protection, thyristor rectification, frequency conversion speed regulation, resistance welding, etc.

Disadvantages:
Due to limitations in manufacturing processes and materials, the accuracy of a normal 50Hz sine wave is not as good as that of conventional transformers. It can reach a maximum level of 0.2.

Parameters:
Input current: 0-300A
Output voltage: current differential di/dt 1mV5%/A (50Hz)
Response frequency: 1Hz~500KHz
Linearity: 0.5%, 0.2%
Appearance: 17X16X19 5 through-hole mm

Mainly used for measuring severely distorted sine wave current, impulse current, and pulse current (cannot measure pure DC current).
Note: YX250 series transformers can be customized according to user requirements.
