CS series new zero magnetic flux current sensor is a sensor developed based on the magnetic modulation and magnetic balance principles. It uses the mechanism of alternating saturation of high permeability iron core under the saturation excitation of alternating magnetic field to quickly modulate the primary side current to the secondary side coil through the equal ampere turn principle, so that the magnetic field generated by the compensation current output by the secondary side coil and the magnetic field generated by the primary side current cancel each other
The current of the secondary coil can accurately reflect the magnitude of the primary current.
CS series new zero flux current sensor can meet the high-precision measurement of current signals with a bandwidth of DC ~ 800KHz and a range of 1mA ~ 25kA. The current sensor is divided into three series according to the ratio difference and angle difference index:
G series current sensor: the accuracy is better than 2 ‰. It is mainly used for accurate detection of various current signals in the measurement and control field. Such as: high-precision current detection of batteries, photovoltaic cells, electric vehicle charging piles, etc.
P series current sensor: the accuracy is better than 20ppm, and the angle difference under the reference frequency is less than 1 ', which is mainly used for power measurement or high-precision test application concerned with current phase index. Such as: high-precision inspection and detection of motors, frequency converters, power transformers, new energy vehicles, photovoltaic inverters, wind power, fans / pumps, rail transit, ship integrated power and electric propulsion, aviation power supply, etc.
J series current sensor: the accuracy is better than 1ppm, and the angle difference under the reference frequency is less than 1 ', which is mainly used as the current measurement benchmark of the variable-frequency electricity metering verification device.
