GAOHUI IGBT Rectifier Tin Plating Power Source 12V 2500A

GAOHUI 12V 2500A IGBT rectifier is engineered for high-volume tin plating operations, delivering stable low-voltage DC power at 30kW. This unit targets production lines demanding precise control over current density for matte tin process and continuous strip tinning applications. Designed as an industrial high frequency rectifier factory solution, it replaces older SCR units with significantly higher efficiency and tighter output regulation. Whether you are pricing a new line upgrade or sourcing a heavy-duty DC power supply price for high-amperage tin baths, this model offers a superior cost-to-performance ratio.
Part 1 Key Features & Engineering Highlights
HIGH-FREQUENCY IGBT TECHNOLOGY: Utilizes advanced IGBT switching at over 20kHz, ensuring ripple of less than 1% and immediate response to load changes. This guarantees uniform grain structure in tin deposits, critical for PCB busbar plating.
ROBUST 30KW CAPABILITY: Outputs 2500A continuously at 12V, built for 24/7 industrial schedules. The drawer-type structure allows for rapid maintenance and module swap without downtime.
PRECISE CONTROL INTERFACE: Digital control with 0.1% accuracy for both voltage and current regulation. Stable DC output eliminates deposits variance and reduces anode consumption in high-speed lines.
THERMAL MANAGEMENT SYSTEM: Integrated forced air cooling with redundant fans and oversized heat sinks ensures low internal temperatures even at maximum load.

Part 3 Advanced Built-in Protection Systems
The IGBT rectifier manufacturer design philosophy at GAOHUI integrates multi-layer safety as a core feature. This power supply is equipped with real-time overcurrent and short-circuit protection that triggers automatic shutoff in under 2 microseconds. Incoming overvoltage and undervoltage detection isolates the unit from harmful line power surges. A dedicated overtemperature protection loop monitors both IGBT junction temperature and ambient air, reducing output power gradually before a hard shutdown to prevent catastrophic failure. Phase loss and phase sequence protection ensure the unit only operates with a correct three-phase input.
Part 4 Target Industrial Applications
This DC power source is specifically optimized for matte tin process and tin plating lines. Primary applications include continuous strip tinning for electronic component leads and connectors, high-speed wire plating, and detailed PCB busbar plating where tight current control prevents burning. The 12V 2500A configuration also excels in barrel and rack tin plating operations that require high ampacity for large load volumes but need the low voltage specific to tin deposition chemistry.
Part 5 Customization and Tailored Engineering Services
As a custom current voltage rectifier provider, GAOHUI factory capabilities cover 1V to 1000V output and 1A to 100,000A. This unit can be modified with integrated Process Timer for precise cycle control, Multi-Stage Profile Control for ramping current during deposit stages, and an Ampere-Minute Integrator for tracking bath metal consumption. For advanced lines, we integrate Automatic Reverse Polarity cycling and Soft-Start sequences to prevent shock to workpieces. Standard communication protocols include RS485 Modbus RTU, Ethernet, and 4-20mA analog interface. Optional Pulse Functions from 1 to 3000Hz adjustable can be added to alter grain structure of the tin deposit. Specify your exact input voltage and cooling requirements during quotation.
