as an authorized distributor of ECG Kokusai is proud to introduce the latest innovation the Impulse Winding Tester DWIT-05.

What is an Impulse Winding Tester?

An Impulse Winding Tester is an essential instrument used to evaluate the quality of coils and electric motors. It applies a high-voltage pulse to the winding and measures the response waveform to detect any irregularities such as:

• Turn-to-turn short circuits within the coil
• Variations or inconsistencies among coils in the production batch
• Insulation degradation or breakdown

Key Features of the ECG DWIT-05

• Supports a maximum test voltage of 5,000 V
• Full digital control system for highly accurate and stable measurements
• Color LCD display for clear visibility and easy operation
• Waveform comparison function for quick and efficient coil inspection
• USB / LAN connectivity for data saving and waveform analysis via PC
• Supports multiple test modes — Manual / Auto
• Equipped with an overload protection system to ensure operator safety

Ideal for Industrial Applications

• Motor, transformer, solenoid, relay, and coil manufacturing lines
• R&D departments requiring precise evaluation of prototype windings
• Production lines seeking consistent and reliable quality control

Equipped with ECG’s highly sensitive Impulse Test Method, the DWIT-05 enables users to detect coil defects at an early stage — ensuring higher testing accuracy, reducing production loss, and improving overall manufacturing quality and efficiency.
