Why Choose This IGBT Tester?

When you need to validate the voltage withstand capability of power semiconductors, reliability matters. This tester combines a broad voltage range with a built‑in 1000 V discharger, eliminating the need for separate equipment. Its intuitive interface reduces setup time, while safety interlocks protect both the user and the device under test.

Typical Applications

• Quality control in semiconductor manufacturing.
• Repair and maintenance of power converters and inverters.
• R&D testing for automotive, renewable energy, and industrial automation.
• Educational labs teaching high‑voltage electronics.
• Field diagnostics for power distribution equipment.

How to Use

1. Connect the appropriate probe to the device under test.
2. Select the desired voltage range on the LCD menu.
3. Press “Start” – the tester will ramp up voltage until the breakdown point is reached.
4. The peak voltage is captured and displayed; the built‑in 1000 V discharger safely releases stored charge.
5. Record the result and repeat as needed.
