Micro-arc Oxidation (MAO) / Plasma Electrolytic Oxidation (PEO) Power Inverter

This power supply is specially designed for surface modification of aluminum, titanium, magnesium and their alloys by means of micro-arc oxidation.  It adopts our advanced high-frequency switching technology and the advanced electronic design yields excellent output waveform and output characteristics.  It is also equipped with positive and negative pulse outputs.  The frequencies, positive and negative voltages, as well as pulse widths can be adjusted individually.  The power supply has over-current and over-temperature protections ensuring high performance in surface treatments.

Main characteristics

1. Advanced switching technology with small footprint, stable operation, low noise, and low electrical interference
2. Individually and continuously adjustable frequencies, positive and negative voltages, as well as pulse widths
3. Multiple circuit protection modes enabling stable operation
