30A Intelligent voltage drop simulator

Electrical grid connection, electronic equipment subject to grid voltage dips, short interruptions and voltage variations. The reasons for these changes are due to the grid voltage, substation equipment failure or a large load changes suddenly. Testing such phenomena, it is designed to test electrical and electronic equipment encountered voltage mutations, can avoid unsafe operating conditions. It is not only able to conduct the test phase, but also to achieve any two or three phases at the same time test. VDG-1130G (30A) with six separately controllable semiconductor switches, each having an electron short circuit protection.
