Product Features and Applications
- Energy-saving and lightweight : The required test power capacity is only 1/Q of that of traditional equipment, and the weight and volume are about 1/10 of that of conventional equipment, making it easy to transport on site.
- Waveform purity : Outputs a sine wave with a distortion rate of <1.0%, avoiding harmonic peaks that could cause the test sample to break down.
- Safe and reliable : When the test sample breaks down, the circuit quickly detunes and the current drops sharply, eliminating the risk of large current burning out the fault point, and there is no recovery overvoltage.
- Intelligent and easy to use : Supports three modes: fully automatic, manual, automatic tuning, and manual voltage boost. It has built-in overvoltage/overcurrent/flashover/zero-point start protection and can store and print test data.
- Advanced technology : It adopts a DSP platform, has a user-friendly human-computer interaction, and supports function upgrades and parameter customization.
