It features high-precision control, wide power coverage, and strong environmental adaptability, providing global industrial customers with motor speed regulation and energy efficiency optimization solutions from single equipment to system-level applications.

1.Core Advantages: Technology Empowers, Defining High-Efficiency Speed Regulation Standards

Full-Scenario Power Coverage: Single-unit power ranges from 0.37kW to 800kW, and multi-unit parallel operation supports expansion up to 3MW, meeting full-power demands from micro-equipment to large industrial production lines.
Vector Control Technology: Adopts Closed-Loop Vector Control Technology with speed control accuracy ≤0.2%, speed regulation range 1:100, compatible with both asynchronous and permanent magnet synchronous motors. The heavy-load starting torque exceeds 200% (at 0.5Hz), precisely matching the dynamic response requirements of loads such as machine tools, lifting equipment, and fans.
High-Reliability Design: Models of 7.5kW and below adopt independent air duct + exposed radiator design for dust prevention and easy maintenance. It supports wide voltage adaptation (±15% fluctuation), operates stably at -10~50℃, and works reliably at altitudes ≤1000m, maintaining high efficiency even under extreme conditions.
Intelligent Expandability: Standard configuration includes 485/Can/PN bus interfaces, with optional IO expansion cards and PG cards. It supports customized functions such as energy feedback and multi-machine linkage, enabling seamless integration into industrial automation systems.

2.  Industry Applications: Full-Field Adaptation, Driving Industrial Upgrading

General Industry: Frequency conversion speed regulation and energy-saving transformation of fans, pumps, and conveyors, with an average energy-saving rate of 20%-40%.
High-End Manufacturing: Precise positioning of machine tool spindles and stable speed regulation of lifting equipment, meeting the precision requirement of 0.1r/min.
New Energy Supporting: Intelligent drive of photovoltaic water pumps and wind power auxiliary machines, adapting to voltage fluctuations and load changes in new energy scenarios.
