TA1500 AC/DC Current Standard Source
1. Summary
TA1500 is a series of AC current standard source devices, which can output high stability and high accuracy AC current large current, suitable for calibrating AC current ammeters, current transformers, Current sensors and other devices.
2. Features
• Supports combined outputs from multiple module sources up to 6 kA.
• Test frequency: DC, 10 Hz ~ 65 Hz (400, 1kHz optional).
• Accuracy class:Class 0.02 or Class 0.05
• AC and DC current outputs use the same bus and terminal block
• DC current is bipolar and does not require relay commutation.
• Support external control console to adjust the current output.
• The software controls the slow rise and fall of the large current, and the overshoot amplitude is small.
3. Applications
☆ Calibrate the AC current ammeter |
|
• Class 0.02 specification: Suitable for calibrating large AC-DC ammeter of class 0.1 and below. • Class 0.05 specification: Suitable for calibrating large AC-DC ammeter of class 0.2 and below. |
☆ Calibrate current sensor / transformer |
|
• TA1500 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. Functional features
☆ 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, current can be superimposed 2~21 harmonics @ 50 Hz. • The amplitude and phase of each harmonic can be set independently, and the output waveform and spectrogram can be displayed. |
