High-Current DC Rectifiers for Electroplating and Electrolysis
GAOHUI manufactures high-frequency AC-DC rectifier power supplies for electroplating, anodizing, electrolysis, electrowinning and hydrogen production. Output ratings, cooling and control functions are configured against the process, load and operating requirements.
Industrial Rectifier Manufacturer
Our industrial rectifiers convert low-voltage AC input into controlled DC output through high-frequency switching and isolation. Standard projects are evaluated around AC 220 V, AC 380 V or AC 415 V input, with the appropriate input selected according to output power and project conditions.
Each system is specified from the required current, voltage, duty cycle, cooling method, control mode and installation environment. Pulse, polarity reversing, communications and programmed control are included only when confirmed for the project.

Rectifier Selection Starts with the Process
A reliable selection begins with the actual working point rather than a generic model number. Provide the process, required DC current and voltage, load or electrode area, continuous operating time, cooling conditions, control mode and communication requirements. GAOHUI will evaluate the output rating and available configuration for the project.
