GAOHUI Electropolishing Power Supply (15V/1000A) Advanced Surface Deburring System

EXECUTIVE SUMMARY
This GAOHUI 15V/1000A rectifier is purpose-built for demanding electropolishing and electrochemical metal finishing processes. Designed as the reverse of electroplating, it delivers precise, ripple-free DC current to selectively remove surface imperfections, burrs, and micro-peaks from stainless steel and other alloy components. Engineered to replace outdated high-voltage transformer systems (often 100V/1000A), our 15V/1000A unit provides superior anodic dissolution control at lower voltage, reducing energy waste while improving surface brightness for mirror finish polishing. As a trusted industrial high frequency rectifier factory, we optimize every component for continuous industrial duty cycles.
PART 1 KEY FEATURES & ENGINEERING HIGHLIGHTS
This electropolishing power supply utilizes high-frequency IGBT switching technology (20-50kHz) to deliver exceptionally stable, low-ripple DC output (less than 1% ripple). The precise voltage regulation (setpoint ±0.5%) ensures consistent metal removal rates across the entire workpiece surface, critical for achieving uniform mirror finishes. The unit’s robust forced-air cooling system and heavy-duty bus bars provide reliable operation in harsh shop environments. For buyers comparing heavy-duty DC power supply price, this model offers unmatched value-per-ampere for sustained electropolishing production runs. The digital controller supports real-time monitoring of accumulated ampere-minutes, ensuring exact material removal per batch.

PART 3 ADVANCED BUILT-IN PROTECTION SYSTEMS
Your production line halts are costly. This GAOHUI unit includes a multi-layer fault protection suite: Phase-Loss Protection to prevent motor controller damage, Over-Temperature Shutdown with auto-restart once cooled, Short-Circuit Protection on the DC bus, and Surge/Spike Suppression on the AC input. The internal IGBT modules are isolated with temperature sensors; if internal heat rises beyond safe limits, an audible alarm triggers, and the unit reduces power gracefully. This design reliability is why many clients choose this IGBT rectifier manufacturer for mission-critical electrochemical surface treatment.
PART 4 TARGET INDUSTRIAL APPLICATIONS
This 15V/1000A rectifier excels in:
– Stainless Steel Mirror Finish Polishing and Brightening
– Electrochemical Deburring of Precision Machined Parts (medical devices, aerospace components)
– Electrolytic Descaling and Oxide Removal
– Removing Heat Treatment Scales and Contaminants
– Three-dimensional workpiece passivation
Its low voltage, high current profile matches the specific electrochemical dissolution requirements of phosphoric-sulfuric acid electropolishing baths (e.g., ratios of 63% to 15%). The digital controller provides pre-set process recipes for different material grades, ensuring repeatable results job-after-job. As a specialized custom current voltage rectifier, we tailor the wave-form to your specific electrolyte chemistry.
PART 5 CUSTOMIZATION AND TAILORED ENGINEERING SERVICES
Beyond the standard 15V/1000A, GAOHUI offers complete custom voltage and current ranges: 1V to 1000V DC and 1A to 100,000A DC, with any standard three-phase AC input voltage (e.g., 220V, 380V, 415V, 480V). The output is pure DC. Optional engineering modules include:
– Process Timer: Automatic shutdown after exact contact time.
– Multi-Stage Profile Control: Ramp-up, soak, and step-down profiles.
– Ampere-Minute Integrator: Digital totalizer for charge passed (Ah/mAh).
– Automatic Reverse Polarity (ARP): Programmed periodic reverse cycles for specialized electro-deburring applications.
– Pulse Functions: Adjustable from 1Hz to 3000Hz, with variable duty cycle (10% to 90%), for achieving micro-fine texture control on high-polish surfaces.
– Soft-Start feature: Prevents chemical splash and electrode damage during initial power application.
– Interface protocols include RS485 Modbus RTU (standard), Ethernet/IP, and 4-20mA analog control.
– Remote software: Full data logging and recipe management via windows PC.
