1. Summary
TA1300 is a series of AC current standard source devices, which can output high stability and high accuracy AC high current, suitable for calibrating AC ammeters, current transformers, current sensors and other equipment.
2. Features
• Supports combined outputs from multiple module sources up to 6 kA.
• Maximum fundamental frequency: 65 Hz / 400 Hz / 1kHz optional.
• Accuracy: Class 0.02 or Class 0.05
• Harmonic output function (optional)
• Support external control console to adjust the current output.
3. Applications
☆ Calibrate the AC ammeter |
|
• Class 0.02 specification: Suitable for calibrating high power frequency ammeter of class 0.1 and below. • Class 0.05 specification: Suitable for calibrating high power frequency ammeter of class 0.2 and below |
☆ Calibrate current sensor / transformer |
|
• TA1300 can be used as a primary current input to the sensor or transformer under test. • In combination with a precision ammeter or voltmeter, the sensor or transformer is calibrated using the direct measurement method. |
4. Characteristics
☆ Measurement output and adjustment mode |
|
• With the "fixed-point output" method, you can directly set the required output value by clicking the touch screen. • The unit switches fully automatically to the optimal range output. |
☆ Harmonic output (optional). |
|
• Optional harmonic output function, the current can be superimposed 2~11th harmonic @ 50 Hz. • The amplitude and phase of each harmonic can be set independently, and the output waveform and spectrogram can be displayed. |
