Description
Overview
GAOTek 3-Phase Controlled Relay Protection Tester is a high-performance embedded industrial control computer with a Windows XP operation interface for easy and fast operation. It has software self-calibration function, which greatly improves its accuracy and stability. Its power amplifier adopts high-fidelity linear power amplification, which not only ensures the accuracy of small current, but also ensures the stability of large current. It adopts USB interface to communicate with PC directly, without any adapter cable, making it convenient to use. Its main control board adopts DSP+FPGA structure and 16-bit DAC output, which can generate 2000 high-density sine waves per week for the fundamental wave, which greatly improves the quality of the waveform and the accuracy of the tester.
