GAOHUI Electropolishing Power Source 15V 1000A High Frequency IGBT Rectifier

Executive Summary
This GAOHUI 15V 1000A Electropolishing Power Source is engineered for high-volume industrial production of large metal parts where processing time is critical. Delivering 1000A of pure DC current at low voltage, this unit cuts electropolishing and electrochemical deburring cycles dramatically compared to standard battery chargers or lower-amperage systems. Designed for continuous 24/7 operation in tough factory environments, it transforms a process that might take hours into a predictable 20-minute cycle. As an industrial high frequency rectifier factory, GAOHUI ensures every unit delivers superior ripple control for mirror finish polishing and stainless steel passivation.
Part 1 Key Features and Engineering Highlights
IGBT Resonance Technology and Precision Output
The heart of this unit is its high-frequency IGBT inverter design, providing an extremely stable DC output with minimal ripple. This smooth DC current is critical for achieving a uniform, mirror-like finish on complex geometries and large surface areas during stainless steel electropolishing and electrochemical deburring operations. The heavy-duty construction enables consistent 1000A delivery without voltage droop, ensuring repeatable results.
Constant Voltage and Constant Current Control
Switch seamlessly between CV and CC modes to match specific electrolyte conductivity and part surface area requirements. This adaptability is essential for processing a diverse range of part sizes from precision tubes to massive sheet metal panels.
High Efficiency and Intelligent Cooling
Achieves greater than 90% conversion efficiency, reducing operational electricity waste and heat generation. The forced-air cooling system is designed for high ambient temperature environments common in metal finishing shops. For strict pollution and corrosion requirements, optional water-cooled configurations are available.
Rugged Industrial Construction
Built with a heavy-gauge steel enclosure and corrosive-resistant powder coat paint. All electronic components are conformal coated to protect against moisture and acidic fumes prevalent in electropolishing and passivation lines. This ensures long service life even in the harshest electrolytic surface treatment environments.

Part 3 Advanced Built-in Protection Systems
Overcurrent Protection (OCP): Instantly limits output current to prevent damage to the workpiece or electrolyte overheating.
Short Circuit Protection (SCP): Solid-state detection triggers immediate shutdown of heavy-duty DC power supply price outputs to protect the IGBT modules.
Overvoltage Protection (OVP): Monitors capacitor bank and output voltage, disconnecting drive signals if thresholds are exceeded.
Over Temperature Protection (OTP): Multiple NTC sensors across the main heatsink and IGBT modules; activates fan stage control and shutdown if internal temperature exceeds safe limits.
Reverse Polarity Protection: Internal circuitry prevents damage from accidental incorrect connection to the workpiece.
Soft-Start Circuitry: Gradually ramps up output voltage upon start command, preventing sudden current surges that can damage thin parts or sensitive coatings.
Part 4 Target Industrial Applications
Stainless Steel Electropolishing: Achieve mirror finish and high brightness on 304, 316, and 17-4 PH stainless parts such as food processing equipment, pharmaceutical vessels, and architectural panels.
Electrochemical Deburring: Remove microscopic burrs from machined edges, internal cross-holes, and gear teeth without mechanical stress or micro-cracks.
Mirror Finish Polishing: Produce a reflective, low-microinch surface finish on non-ferrous metals including aluminum, titanium, and copper alloys.
Metal Passivation: Enhance corrosion resistance by removing free iron from the surface of stainless steel components.
Precision Surface Cleaning: Remove heat tint, light scale, and contamination from welded or laser-cut edges.
