Part 3: Advanced Built-in Protection Systems
The GAOHUI 300V 3000A rectifier includes comprehensive protection to safeguard both the power supply and the plasma electropolishing process. It features overvoltage protection (OVP) that immediately shuts down output if voltage exceeds a set threshold, preventing damage to the workpiece or electrolyte bath. Overcurrent protection (OCP) limits current spikes during arc ignition, while overtemperature protection (OTP) triggers a thermal shutdown or reduces output power if internal heat sinks exceed safe limits. Short-circuit protection (SCP) instantly disconnects the output in case of a direct fault, and reverse polarity protection prevents damage from incorrect cable connections. An additional arc detection module monitors plasma stability and can initiate a soft shutdown if erratic arcing is detected, ensuring operator safety and process consistency.

Part 5: Customization and Tailored Engineering Services
As a leading IGBT rectifier manufacturer, GAOHUI offers full customization from 1V to 1000V and 1A to 100,000A, with AC input and DC output only. We engineer custom functional modules to match your exact process requirements, including a Digital Process Timer for precise cycle control, a Multi-Stage Programmable Profile Control for complex voltage/current ramping, and an Ampere-Minute Integrator for accurate plating thickness monitoring. An Automatic Reverse Polarity module enables periodic current reversal for improved surface uniformity, while a Soft-Start Ramp-Up feature prevents thermal shock to the electrolyte and workpiece. Local control is via a push-button panel or HMI touch screen, with remote control through RS485 Modbus RTU, Ethernet, or 4-20mA analog signals. For pulsed applications, we integrate Pulse Functions with 1-100% duty cycle and 1-3000Hz frequency adjustable, ideal for advanced plasma polishing and micro-arc oxidation processes. All units undergo rigorous factory testing to ensure reliability in heavy-duty DC power supply applications.
