Product Introduction
The lightning impulse voltage tester is a professional device with a luxurious aluminum alloy outer box design. The working principle is based on the Marx circuit, which generates high-voltage shock waves by charging and discharging multi-stage capacitors in parallel to simulate lightning waveforms for non-destructive testing of electrical equipment.

Product Features
High Stability Output
The lightning impulse voltage tester uses advanced voltage stabilization technology and has a built-in high-precision voltage stabilization module. The voltage fluctuation coefficient under standard testing is less than ±0.5%.
Precise Voltage Control
The lightning impulse voltage tester uses advanced microprocessor control technology to accurately adjust the impulse voltage amplitude, wavefront time and half-peak time. The wavefront time adjustment accuracy is ±0.1μs, and the half-peak time adjustment accuracy is ±1μs, which can accurately simulate the standard lightning impulse waveform.
