ZX-702 Three Phase Microcomputer Relay Protection Tester

The ZX-702 Microcomputer Reply Protection Tester adopts high-speed and high-performance digital signal processor, which run fast and has wide transmission bandwidth. The algorithm of two precision algorithm is applied to generate arbitrary high-precision waveforms. Because of the integrated structure, each part is tightly combined, the data transmission distance shorte and the structure is compact.
