Overheating: Intelligent fan speed regulation maintains stable junction temperature in the IGBT modules.
Short Circuit: Instantaneous response dedicated hardware interrupt.
Phase Loss: Prevents machine start-up if any input phase is missing, protecting the main transformer.
Reverse Polarity Alarm: Visual and audible warning prevents connection errors to the work bus.
Part 4 Target Industrial Applications
This 15V 1500A model is the primary workhorse for architectural profile finishing where precise 0.5-0.8 mil coatings are required. It efficiently handles batch processes for automotive trim, lighting components, and consumer electronics frames. It is also ideal for decorative and functional hard-coat anodizing jobs that demand stable current delivery at low voltage. The unit serves as a reliable foundation for high-volume sulfuric acid anodizing lines producing consistent results shift after shift.
Part 5 Customization and Tailored Engineering Services
GAOHUI provides complete custom current voltage rectifier services to match your exact process specifications. We are a dedicated industrial high frequency rectifier factory capable of building any system from 1V to 1000V DC and 1A to 100,000A DC. Input is AC three-phase; output is always pure DC. Optional add-on modules include Process Timer, Multi-Stage Profile Control for ramping voltage in programmed steps, Ampere-Minute Integrator for automatic bath replenishment, and Automatic Reverse Polarity for specialized surface treatments. Units can be fitted with a soft-start feature to prevent load surge at startup. Connectivity is ensured via RS485 Modbus RTU, Ethernet IP, and 4-20mA analog control interfaces. For advanced surface finishing, a Pulse Function is available with adjustable frequency from 1 Hz to 3000 Hz, allowing modulation of current to improve oxide layer density.
