PART 3 ADVANCED BUILT-IN PROTECTION SYSTEMS
Your process demands zero tolerance for downtime. This unit includes an exhaustive suite of defenses ensuring your electrical assets and your expensive tanks are safe. Instantaneous electronic short-circuit protection prevents catastrophic arc events. Overheating sensors trigger a controlled shutdown sequence, safeguarding the IGBT modules from thermal runaway. The unit also features a loss-of-phase and undervoltage lockout to protect line integrity. Additionally, the dual-section cabinets isolate control circuitry from high-current paths, guaranteeing operator safety and stable digital control signal integrity.
PART 4 TARGET INDUSTRIAL APPLICATIONS
Decorative & Protective Anodizing – Perfect for dye tank coloring and sulfuric acid anodizing where accurate constant voltage maintains the porous oxide layer required for bright, vibrant finishes on consumer goods and architectural aluminum.
Hard Coat Anodizing – Delivers the high current stabilization necessary for thick, wear-resistant oxide coatings up to 50 microns. Suited for mechanical parts, hydraulic components, and aerospace aluminum treatment requiring extreme surface hardness.
Custom Industrial Electroplating – The low-ripple DC output also serves as a robust solution for various electroplating configurations beyond anodizing, offering flexibility for job shops and specialized coating lines seeking a multi-purpose power source.
PART 5 CUSTOMIZATION AND TAILORED ENGINEERING SERVICES
We understand that standard off-the-shelf units rarely fit perfectly. Our factory accepts full custom engineering support. While this unit is standardized at 24V and 2000A, we provide a custom current voltage rectifier service capable of specific ranges from 1V-1000V and 1A to 100,000A, purely DC output. Enhance your process with modular automation add-ons:
Process Integration Modules – Incorporate a Process Timer for automatic shut-off at specified amp-minute counts, essential for consistent layer thickness. Multi-Stage Profile Control enables ramping and stepping sequences (e.g., voltage or current ramps) to optimize finish quality on mixed loads.
Digital Control & Reporting – Equipped with an Ampere-Minute Integrator for electroplating calculations, plus an Automatic Reverse Polarity (ARP) function for de-plating or cleaning cycles. Use Soft-Start to manage thermal shock to your rectifier and tank solution.
Factory Automation Interfaces – The optional RS485 or Ethernet connection connects directly to your PLC for full monitoring and control. Analog 4-20mA inputs and outputs allow for remote proportional control. For advanced surface engineering, the system can include Pulse Functions operating at 1-3000Hz adjustable frequency, enabling specialized pulsed anodizing techniques to enhance coating properties and efficiency.
