The Eucol U9845 Impulse Winding Tester is a versatile winding testing device with a pulse voltage of 100V~5000V at 10V steps, 5%±10V. Eucol U9845 test systems utilize switching components controlled by high stability, high-voltage impact power and thyristor modules. This configuration dramatically increases stability, reliability and measurement precision during testing. The Eucol U9845 can be operated over four high-voltage channels and through one of four waveform comparison methods: area, differential area, corona and differential phase. Eucol U9845 impulse winding testers possess an advanced 32 bit CPU and a memory depth of 6500 bytes.
