High-performance AC drive HD9X series

variable-frequencymedium-voltagehigh-power

The HD90XS series medium-voltage AC drive is designed based on the two-quadrant synchronous/asynchronous motor control platform, featuring a unit-cascaded bypass-capable architecture. This drive meets modern industrial demands for energy efficiency optimization and process speed regulation in large/medium-sized fans and pumps. Benefit Application algorithm for general motors Disturbance-free synchronous transfer technology Transformer secondary protection technology Application algorithm for general motors Based on stator flux-linkage closed-loop control algorithm to achieve high-performance operation while eliminating dependence on motor rotor parameters. With rapid dynamic response, it supports both energy-saving applications in wind turbines and pumps, as well as conveyors and compressors. The closed-loop control algorithm prevents parameters from being affected after long-term operation, ensuring stable operation. Disturbance-free synchronous transfer technology Disturbance-free synchronous transfer technology enables seamless bidirectional switching (grid-to-VFD/VFD-to-grid) with cost saving more than 10% and low impact on the grid during grid-to-VFD/VFD-to-grid switchover. Transformer secondary protection technology Hiconics Transformer Secondary Protection Technology As a critical component in the AC drive, transformers now integrate our proprietary secondary-side protection technology to prevent fire accidents and equipment damaged caused by short circuit in the secondary side of the transformer, ensuring property integrity and minimizing the fault range.
