Product Introduction
 

XL-3600T3 DC Current Sensor Calibration Bench Mainly composed of a high-power DC current source, DC current standard sensor, DC current sensor calibrator, and calibration bench body. The DC current sensor calibrator features a dual-CPU architecture core, powerful functions, uses a 24Bit AD chip and 512 times oversampling technology to greatly expand bandwidth and improve measurement accuracy. It also uses an FIR filter to enhance dynamic range and signal-to-noise ratio. The independently developed human-machine interaction software adopts a popular design, making it simple and convenient to use. It supports error calibration of primary current 0~1000A and secondary output as voltage type (0~7V) or current type (0~100mA) DC current sensors.

Features
 

• Mainly used for DC error calibration of DC current sensors.
• Built-in high-power DC source capable of outputting unipolar pure DC signals, DC signals superimposed with AC ripple signals, and can also test AC ripple signal ratio and phase difference.
• Three-station design allows testing of three DC current sensors simultaneously; supports calibration of DC current sensors with secondary voltage or current output.
• The current sensor calibration system integrates traditional equipment (components) in one, built-in transformer calibrator, standard current sensor, and high-power DC current source, with a high degree of automation.
• All devices (components) inside the unit are detachable for convenient individual inspection.
• Can display the waveform of the sensor under calibration in real time to monitor waveform distortion of the tested sensor.
• Calibration schemes can be freely edited as needed to achieve fully automatic calibration.
• Fully automatic testing according to the test scheme, with automatic saving of test data.
• Automatically controls the high current source to output different calibration points during automatic testing.
• Automatically generates test reports, which can be edited according to user templates; reports can be generated based on customer-provided templates, which are freely editable.
• This product has strong adaptability and scalability, supporting future upgrades.
• Provides secondary communication protocol, supporting integration with various current transformer calibration systems.
