FAQ
How does the SPD20KVPOS ensure maximum operator safety during 20kV high-voltage corona polarization?
Operator safety, especially in educational environments, is our top priority. The system utilizes isolation shielding technology to completely prevent electrical leakage. Furthermore, it is equipped with strict safety interlocks that prevent any high voltage generation during sample handling. If a sample dielectric breakdown occurs, the independent protection circuit instantly triggers a light alarm and cuts off the high-voltage output.How does the intelligent visual monitoring system assist researchers and students?
The device features an intuitive visual monitoring system that displays the polarization current, state, and process parameters in real time. By continuously observing these dynamic changes, users can easily determine the optimal polarization conditions for different thin films and achieve the best possible polarization effects, making it highly valuable for theoretical and practical teaching.What types of samples can this compact device handle, and does it support negative corona?
Despite its small precision footprint (350×300×160 mm), the SPD20KVPOS accommodates both film and bulk samples up to 50 mm in diameter (Φ) and 10 mm in thickness (d). It standardly provides 0~20kV positive air corona polarization, but can also be customized for negative corona polarization applications upon request.
