• 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

TA1300 AC Current Standard Source 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 AC Current Standard Source Calibrate current sensor or 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

TA1300 AC Current Standard Source 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).

TA1300 AC Current Standard Source 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.
