AHV 20kV 200mA High Voltage AC Power Supply for Plasma Applications

20kV (40kV peak to peak) plasma, often generated via dielectric barrier discharge (DBD) or corona discharge, is primarily used for high-energy industrial and medical applications, including surface cleaning, activation, and thin-film deposition in manufacturing.

AHV 20kV 200mA 4000W series high voltage AC power supply provides 20kV (40kV peak to peak) high-stability high voltage pulses at high frequency (1kHz to 100kHz) to plasma systems. The HV output is from 0 to 20kV adjustable at either a fixed frequency or an adjustable frequency range selectable from 1kHz to 100kHz.

Options of fixed frequency range: 1kHz, 2kHz, 3kHz, 4kHz, 5kHz, 8kHz, 10kHz, 20kHz, 30kHz, 40kHz, 50kHz, 100kHz

Options of adjustable frequency range: 2kHz ~ 8kHz; 5kHz ~ 10kHz; 10kHz ~ 20kHz; 10kHz ~ 30kHz; 20kHz ~ 30kHz; 20kHz ~ 40kHz; 20kHz ~ 50kHz; 30kHz ~ 40kHz; 30kHz ~ 50kHz; 50kHz ~ 100kHz

Key applications of 20kV (40kVpp) plasma include:

• Surface treatment and activation: used to increase the surface energy (wettability) of plastics, metals, and glass, enabling better adhesion for printing, painting, or bonding.
• Surface sterilization: used to deactivate bacteria and microorganisms on medical devices and, at lower temperatures (<50°C), for food safety.
• Agricultural applications: used to remove ethylene gas and sterilize storage environments to prolong the freshness of produce.
• Material processing and coatings: used in industrial manufacturing for precision etching, cleaning, and applying thin-film functional coatings.
• Environmental protection: used in industrial settings to detoxify exhaust gases and manage industrial waste through plasma oxidation.
• Energy catalyst activation: used to improve the efficiency of fuel cell catalysts by increasing active site density.
