• High reliability design
• Water cooling heat dissipation
• Low noise operation
• High efficiency performance
• Strong environmental adaptability

• Blast furnace blower
• Oxygen compressor
• Boiler induced draft fan
• Sintering main exhaust fan
• Fan and water pump applications

• Precise Torque Control: Independent management of excitation and torque currents for accurate AC motor control
• Superior Performance: Large starting torque, rapid dynamic response, high control accuracy, and strong load capacity
• Versatile Motor Compatibility: Drives both synchronous and asynchronous motors, ideal for demanding loads like ball mills, belt conveyors, and compressors

• Multiple inverters form a network with synchronized power and torque commands
• Ideal for applications requiring balanced power distribution like belt conveyors and friction hoists

• Real-time monitoring of input/output voltage and current waveforms
• Harmonic analysis for comprehensive electrical parameter understanding

• Automatic recording and display of operating status
• Captures 200 data points before and after protection events for easier maintenance and troubleshooting

• Real-time monitoring of each power unit's temperature
• Audible and visual alarms triggered by multiple unit overheating

• Seamless switching between inverter and grid power modes
• Integrated control of multiple motors with soft starting capability
• Maximum current remains at or below rated current during switching

Ensures automatic normal operation after power grid recovery within limited time, adapting to U0 (100% - 0%) grid drop scenarios.

Field power supply and secondary power supply of main transformer serve as hot standby for each other, with seamless switching and failure indication.

Anti-interference design passed national authority tests including electrostatic discharge immunity, surge immunity, and RF electromagnetic field radiation tests.

Air-water cooling system suitable for harsh environments, forming a hot air cold air circulation system for efficient heat dissipation.
