Wound Component EST Scanner - 19035

Chroma's 19035 Wound Component Scanner is a production safety tester designed for test requirements of three-phase motors, double-wound transformers and heater related wound components. Quality verification test items for wound components consist of AC/DC Hipot (dielectric withstanding), Insulation Resistance (IR), and Impulse Winding tests. We have integrated these tests into one unit.

Hipot, IR, and Impulse Winding Test

19035 AC/DC Hipot, IR, DCR
CE Mark

The 19035 is designed to directly connect to a DWX Series Impulse Winding Tester and use the 8-Channel scanning capabilities to reach multiple points in one test instead of switching test points manually.
