WHFD Series High Frequency Electroplating Rectifier


High frequency electroplating rectifier adopts IGBT high frequency inverter soft switch rectifier technology. This inverter rectifier is mainly used as all kinds of metal and nonmetal surface plating rectifier power supplies (like electroplating zinc, nickel, chrome and titanium, and so on). The soft switch electroplating rectifier can also be used as electrolytic rectifier power supply, common anodizing power supply and DC heating power supply, etc. The power supply has a special structure using water cooling method. It has obvious energy saving effect. This inverter rectifier can provide stable current and voltage, and has soft starting and multiple protection functions. The plated layer has excellent compactness, excellent wear resistance, and high rigidity. The soft switch electroplating rectifier shows excellent process versatility in electroplating production. We use export wooden case package after fumigation treatment. With waterproof, anti collision and good fixation, the inverter rectifier's package is strong and durable during transportation to stop damage.
