Comprehensive Transformer Testing Systems
2 in 1 Comprehensive Transformer Testing System

626x series+7631(transformer tester + hipot tester) 2 in 1 comprehensive transformer testing system, one-step test solution. 7631 hipot tester is the main control instrument, which controls the measurement sequence. AC output voltage 5000V, DC output voltage 6000V, able to execute “High voltage” and “Low voltage “tests simultaneously and can test multiple set of windings at the same time. Transformer tester max. test frequency 1MHz and basic accuracy up to ±0.1%. Transformer tester built-in LCR meter function can be used as a LCR meter.
