HD8000 Series Medium Voltage Engineering Drive: Powering Efficiency for Demanding Industrial

Product Overview

The HD8000 Series Medium Voltage Engineering Drive is a high-performance, modular drive system designed for heavy-duty industrial applications requiring robust power delivery and precise control. Engineered with an advanced AC-DC-AC topology, it supports both single-drive and multi-drive configurations, including shared DC bus architectures, making it ideal for industries such as metallurgy, oil and gas, mining, and rail transportation. With a maximum single-unit capacity of 102MVA, the drive accommodates a wide voltage range (1900V to 10kV grid-side input; 660V to 3300V motor-side output), ensuring compatibility with global power standards and seamless integration into diverse operational environments.

Key Features

High-Power Precision Control Equipped with vector control and direct torque control (DTC) algorithms, the HD8000 Series delivers precise speed and torque regulation for motors under extreme loads. Its multi-quadrant operation capability enables efficient energy regeneration during braking, reducing reliance on external resistors.

Advanced Cooling and Durability Featuring an IP54-rated water-cooling system, the drive maintains optimal performance in harsh conditions, including high ambient temperatures and dusty environments. The system supports continuous overload operation at 110% rated current and short-term overloads up to 120% for 60 seconds, ensuring reliability in critical processes.

Harmonic Suppression and Grid Stability Utilizing multi-pulse rectification and active PWM rectifier technology, the drive minimizes harmonic distortion (THDi <3%), enhancing grid power quality and compliance with IEC 61000-3-12 standards.

Intuitive Human-Machine Interface (HMI) A 15.6-inch industrial-grade touchscreen provides real-time monitoring of operational parameters, fault diagnostics, and configuration adjustments. Preloaded application-specific templates streamline setup for common industrial workflows.

Unique Advantages

Modular Scalability The drive’s modular design allows rapid component replacement and capacity expansion. Critical subsystems—such as power cells, control units, and cooling modules—are independently serviceable, minimizing downtime during maintenance or upgrades.

Comprehensive Safety Protocols Certified to CE, IEC, and ATEX standards, the drive incorporates multi-layer protection mechanisms, including overvoltage/undervoltage shutdown, phase-loss detection, and thermal overload alerts. An integrated water-flow monitoring system prevents cooling failures.

Smart Predictive Maintenance Embedded AI algorithms analyze historical and real-time data to predict component wear, such as capacitor degradation or fan lifespan, enabling proactive maintenance planning. Remote access via encrypted cloud platforms facilitates centralized management of distributed assets.
