Key Features & Benefits

• Mega-Current Symmetrical Pulse Output: This rectifier delivers 6000A in both forward (cathodic) and reverse (anodic) polarities. This capability is crucial for depositing uniform zinc-nickel alloys and for managing internal stress in thick deposits, thereby preventing cracking and hydrogen embrittlement.
• Industrial Water Cooling Plant: A dedicated closed-loop water cooling system manages the immense 144kW thermal load. Therefore, it ensures stable, continuous operation and protects critical power components.
• Precision Process Control: The system allows independent programming of forward/reverse current, pulse duration, and cycle counts. As a result, manufacturers can fine-tune alloy composition, coating density, and mechanical properties with exceptional accuracy.
• Automation & Integration Ready: Designed for modern smart factories, it offers extensive communication protocols. Thus, it enables seamless integration into automated production lines and plant-wide monitoring systems.
• High Reliability & Safety: Built with industrial-grade components and multiple layers of protection, this system ensures maximum uptime and operator safety in demanding environments.

Application Advantages

This symmetrical pulse rectifier addresses critical challenges in high-volume manufacturing.

In the Automotive Industry, it is the preferred method for applying corrosion-resistant zinc-nickel coatings on safety-critical fasteners. The pulse reverse process ensures consistent alloy composition, which directly meets stringent industry standards.

In the Aerospace Sector, the ability to plate thick, low-stress deposits on components like landing gear is vital. This system's controlled anodic cycles effectively eliminate hydrogen embrittlement, producing coatings for extreme conditions.

For General Industrial Heavy Plating, such as on large rollers or cylinders, the technology allows faster buildup of functional coatings (e.g., hard chromium) with superior integrity and fewer defects.

Ultimately, this rectifier is a complete process solution. It enables higher-performance coatings, reduces waste from rejected parts, and delivers the reliability required for continuous, high-value manufacturing.
