Overview
The test system is composed of voltage regulator, high current generator and intelligent temperature rise console. It is a three-phase adjustable high current temperature rise test device. It is suitable for the current load test and temperature rise test of bus, switch, current transformer and other test objects. It can work for a long time and has the function of automatic timing and current stability.
