D-KAT Series - 10Kv, 12Kv & 15Kv - Digital Surge Tester

About the D-10KAT, D-12KAT, D-15KAT

The Digital Surge Tester with Bar-to-Bar Test is a comprehensive system designed to check the quality of both AC and DC motors.
It includes a Bar-to-Bar Test function for detecting low impedance in series wound armatures and field coils of DC traction motors.
Equipped with an embedded industrial PC, 8-inch touchscreen display, and advanced software, it enables storage, recall, and printing of test reports.
