■ product overview (customized according to customer needs)

The vs-gzzs fault indicator tester strictly follows the power grid 2017 distribution line fault indicator access test outline. The fault indicator tester adopts high reliable multi closed-loop control technology. The power supply has the characteristics of high output power accuracy, high output power resolution, high stability and reliability, high conversion efficiency, low power grid pollution, constant current and constant voltage. The intelligent DC test instrument adopts Siemens PLC and Taiwan vinylon 10 inch LCD. The software is independently developed without inputting set parameters and automatically testing data.
