Product Description
MEIAL ML-YH DC Anodizing Rectifier & ML-SZS / Single-Wave AC-DC Coloring Power
MEIAL supplies two dedicated SCR power units for aluminum finishing: ML-YH DC rectifier for oxide film growth, and dual/single-wave AC-DC coloring power for electrolytic tinting. Full current range 1KA~25KA, complete multi-protection circuit, PC communication port reserved, air-cooled cabinet, perfectly matched to automatic & manual anodizing lines.
Module 1: ML-YH SCR DC Anodizing Rectifier (For Anodizing Process)
Core Process Mission: DC constant current/voltage output drives aluminum substrate to generate uniform dense anodic oxide film. Stable current density eliminates uneven film thickness, edge thin layers and batch chromatic aberration, the core power equipment for decorative & hard anodizing.
Parameter Item Standard Spec Custom Upgrade
Model ML-YH SCR DC Rectifier Wide voltage version for hard anodizing
DC Output 0-24V continuously adjustable Max 60V heavy hard oxidation
Current Grades 1KA / 3KA / 6KA / 8KA / 10KA / 12KA / 15KA / 20KA / 25KA Parallel connection up to 50KA
Stabilization Accuracy ≤1% voltage & current fluctuation Ultra-precise 0.5% control board
Cooling Mode Industrial forced air cooling Water cooling for non-stop heavy load
Safety Functions Overheat / overcurrent / overvoltage / phase loss lockout External interlock alarm system
Communication Reserved PC control interface RS485 / PLC linkage module
Unique Competitive Advantages
  • Ultra-stable DC output locks consistent current density, solving the industry's biggest difficult of inconsistent oxide film thickness on long profiles & complex castings
  • Multi-layer hardware safety interlock prevents power tripping during full-load continuous production, protecting anode beams, hangers and whole line hardware from burnout
  • All-day air-cooled integrated cabinet requires no water pipeline layout, reducing workshop pipeline construction cost and leakage risks
  • Digital data recording, automatic calculation of oxidation time & total current, support centralized production management of fully automatic lines
Matching Processes & Lines
Decorative sulfuric anodizing, hard wear-resistant anodizing; automatic horizontal / vertical lines, manual sampling oxidation lines, mini lab anodizing equipment.
Module 2: Single-Wave / ML-SZS Dual-Wave AC-DC Coloring Power (For Electrolytic Coloring)
Core Process Mission: Special two-stage output logic: first DC activation, then adjustable AC waveform deposition of metal ions inside oxide micropores to form uniform champagne, bronze, black color layers, targeting single nickel, single tin & mixed salt coloring formulas.
Parameter Item Standard Spec Custom Upgrade
Models Single-Wave Coloring Power / ML-SZS Dual-Wave Coloring Power Multi-wave programmable coloring unit
Output Logic Pre-DC activation + variable AC output Custom DC pre-treatment duration
AC Output Voltage 0-24V adjustable Extended voltage for dark tint
Current Range 6KA / 8KA / 10KA / 12KA / 15KA Parallel high-current model
Supported Waveform Sine wave / asymmetric pulse wave Multi-wave storage for mixed salt formulas
Cooling Mode Full air cooling Low-noise silent cabinet
Formula Storage Multiple coloring process recipes saved Touch screen intelligent control
Unique Competitive Advantages
  • Exclusive DC pre-activation + AC coloring dual mode, greatly improve color uniformity and color repeatability for large batches of architectural profiles
  • Switchable multi AC waveforms compatible with single nickel (Spanish), single tin, mixed salt mainstream coloring baths, one unit fits multiple color production demands
  • Low-loss transformer with oxygen-free copper winding reduces heat generation, stable output under long-time coloring cycle without color fading difference
  • Independent recipe memory function, one-click recall of mature tint parameters to eliminate color deviation caused by manual misoperation
Matching Processes & Lines
Champagne / bronze / matte black electrolytic coloring; full-auto profile production lines, medium-sized manual coloring workshops.
Joint Supporting Value (Why Match Both Power Sets)
Complete surface treatment workflow requires matched dedicated power:
  • ML-YH DC rectifier forms uniform oxide film carrier
  • ML-SZS / single-wave coloring power realizes consistent electrolytic tint on film pores
  • One-stop supply of oxidation + coloring power avoids signal mismatch between different brands, stabilizes overall yield and simplifies after-sales maintenance
