18V 2000A Hard Chrome Plating Rectifier Three Phase High Frequency IGBT Switch Mode

Industrial grade high current rectifier built for demanding electroplating environments where waveform purity, output stability, and energy efficiency are non-negotiable. This 18V 2000A DC power supply delivers precisely adjustable voltage and amperage for both decorative and functional chrome plating, including hard chrome deposition on automotive and industrial components. Rated for continuous heavy-duty cycle operation, this rectifier directly replaces aging silicon-controlled rectifiers (SCRs) with advanced IGBT switched-mode technology for cleaner DC output, lower ripple, and measurable power savings.
Part 1 Key Features & Engineering Highlights
High density modular IGBT inverter topology reduces physical footprint by 60% compared to traditional transformer-based units while maintaining full rated current delivery. The 0-2000A adjustable current and 0-18V adjustable voltage ranges offer fine process control for complex chrome plating profiles, including multi-step ramping for rack and barrel lines. Precision digital metering displays output current accurate to 1A and voltage accurate to 0.1V for real-time bath management.
Three-phase 380V AC input ensures stable operation even under fluctuating mains conditions, with built-in power factor correction above 0.92. The zero-voltage switching (ZVS) design eliminates destructive voltage spikes and harmonics that can compromise chrome deposit quality. This industrial high frequency rectifier factory sources IGBTs from Infineon and capacitors from Nichicon for field-proven reliability.

Part 3 Advanced Built-in Protection Systems
Quad-layer protection architecture prevents catastrophic failure from operator error or process anomalies. Over-temperature threshold with automatic derating protects IGBT modules during prolonged peak current operation. Output overvoltage crowbar circuit clamps spikes below 20V DC. Phase loss detection halts operation if any input phase drops, preventing drive damage. Short-circuit proof design allows the unit to survive a direct load short without component failure. All protection events log to onboard memory with time stamps for troubleshooting traceability.
Part 4 Target Industrial Applications
Designed specifically for decorative chrome plating of automotive trim, bumpers, and grilles where mirror-like finishes require ripple-free DC output. Equally suited for hard chrome plating of hydraulic cylinder rods, piston rings, and die surfaces requiring thick, wear-resistant deposits. The linear adjustment range supports precision amperage control for chrome anodizing and passivation processes. This IGBT rectifier manufacturer explicitly built these units to handle the large surface area loading common in chrome lines.
Part 5 Customization and Tailored Engineering Services
Every unit ships with base 18V 2000A configuration, but full customization is available across our entire product range: 1V to 1000V DC output and 1A to 100,000A DC output. Input capabilities remain AC only, with output strictly DC. For complex plating cycles, optional integrated Process Timer supports hold, ramp, and step sequences up to 24 stages. The Multi-Stage Profile Control module stores 32 independent plating recipes with password protection. An Ampere-Minute Integrator with remote totalizer output can be added for bath loading control. Automatic Reverse Polarity module enables periodic current reversal for chrome etch or stripping cycles. Soft-Start function eliminates current inrush during initial power-up, extending contactor life on automated hoist lines. All units optionally equipped with RS485 Modbus RTU, Ethernet IP, or isolated 4-20mA analog interface for factory automation integration. For pulse plating applications, optional Pulse Functions deliver adjustable frequency from 1Hz to 3000Hz with independent duty cycle control from 10% to 90%. Heavy-duty DC power supply price depends on chosen customization modules, not base unit quality. Custom current voltage rectifier configurations typically achieve 4-6 week lead time from order.
