II. Product Description
Core Functions

• Bidirectional current output: Supports fast switching of positive/negative polarity (Reversing time < 1 second), suitable for processes such as electrolytic polishing and reverse electroplating that require periodic reversing.
• High-precision control: The voltage/current resolution reaches 0.1V/0.1A, suitable for high-precision scenarios such as precious metal electroplating (e.g., gold plating, silver plating).
  Intelligent heat dissipation: The temperature-controlled fan automatically adjusts the speed according to the load, with a noise level < 60dB, and supports continuous operation for 24 hours.
  Technical Advantages
• High-frequency IGBT topology: The efficiency ≥ 88%, which is 15% more energy-efficient than traditional silicon-controlled rectifiers.
• Multiple protection mechanisms: Automatically reduces the rating in case of overload, cuts off instantly in case of a short circuit, and has an IP20 protection level.
• Flexible control: Supports local knob adjustment or remote RS485 communication (Optional 0-5V/4-20mA analog signal control).

Typical Applications

• Surface treatment: Electrolytic polishing of aluminum materials, electrochemical cleaning of stainless steel.
• Precision electroplating: Micro-hole copper plating on PCBs, gold plating of connectors.
• Laboratory research and development: Verification of process parameters for small-batch electroplating.
