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: 0.02 or 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.
