High-Power Rectifier Control Cabinetproduct details

Product Overview:

This product is designed for high-power rectification systems in industries such as chemical processing, metallurgy, military, and scientific research institutes. It is compatible with:

  • Thyristor-based rectification systems (6-pulse, 12-pulse, or multi-pulse topologies up to 24/48-pulse).

  • Diode rectifiers with saturable reactors for high-power applications.


Key Features:

1. Industrial Control System Architecture

  • Dual-core controller: Combines DSP (Digital Signal Processor) and CPLD (Complex Programmable Logic Device) with PLC integration.

  • High reliability: Supports dual-channel hot redundancy backup for critical operations.

2. High-Precision Current Regulation

  • 32-bit DSP: Achieves current stabilization accuracy ≤0.1% and μs-level response speed.

  • Flexible operation modes:

    • Constant Current (CC)

    • Constant Voltage (CV)

    • Constant Power (CP)

3. Fully Digitalized Trigger Pulse Technology

  • CPLD-driven pulse generation:

    • Control angle resolution: <0.1°

    • Regulation accuracy: ±0.5%

    • Implements hardware-equivalent logic via software for ultra-high reliability.

    • Key performance:

      Control angle resolution: <0.1°

      Regulation accuracy: ±0.5%

4. Adaptive & Safety Enhancement

  • Frequency Adaptive Technology: Automatically synchronizes with grid fluctuations.

  • Dual feedback redundancy: AC/DC feedback signals operate in mutual backup mode.

  • Advanced protections:

    • Soft start | Anti-flicker power recovery | Data backup

    • Fault self-diagnosis (supports real-time alarm codes).

5. Flexible Trigger Pulse Configuration

  • Hybrid trigger system:

    • Optical fiber (for EMI immunity)

    • Electrical pulse (cost-effective)

  • Selectable via software based on project requirements.

6. Smart Features & Industrial Connectivity

  • Remote monitoring: Real-time data logging and AI-driven fault analysis.

  • Multi-protocol support:

    • Fieldbus: Profibus, Modbus RTU

    • Industrial Ethernet: Profinet, EtherCAT

7. Wireless Mobile Monitoring

  • IoT-enabled: Wireless data transmission via 4G/5G or Wi-Fi.

  • Mobile APP:

    • Platforms: Android & iOS

    • Functions: Real-time status visualization, alarm push notifications, historical data export.
