1. Core Positioning of 75kW Variable Frequency Drive
The 75kW Variable Frequency Drive belongs to the medium and high-power category, different from small-power VFDs. It is mainly used to drive large motors that bear heavy loads and require continuous stable operation.
It is designed to adapt to the characteristics of high power demand and frequent load fluctuations in heavy-duty scenarios. It can effectively convert electrical energy and adjust motor speed to meet the working needs of large equipment.
Compared with small-power VFDs, it has stronger load-bearing capacity, better heat dissipation performance and more comprehensive protection functions, which are essential for heavy-industry production.
2. Key Performance & Functions of ShuYi 75kW Variable Frequency Drive
ShuYi 75kW Variable Frequency Drive supports vector control and V/F control dual-mode switching, ensuring precise speed and torque control. It can maintain stable output even under sudden load changes.
It has a built-in brake chopper, which can effectively handle the braking energy generated during operation, reduce energy waste and protect the motor and drive system from damage.
The drive is equipped with comprehensive protection functions, including overload, overvoltage, undervoltage and overheating protection. It triggers timely alarms and protection measures to avoid equipment failure.
It adapts to three-phase 380-500V AC input, with 0-400Hz continuously adjustable output frequency, suitable for different industrial power supply conditions and equipment requirements.
3. Typical Application Scenarios
In water treatment and water supply projects, it drives large water pumps, adjusting speed according to water demand to maintain stable water pressure and reduce energy consumption during low-demand periods.
In industrial production, it is widely used in large fans and compressors. It optimizes the operation of equipment, avoids energy waste caused by fixed-speed operation and extends equipment service life.
In mining and metallurgy industries, it drives heavy-duty equipment such as conveyor belts and crushers, providing strong starting torque to ensure smooth startup and stable operation under heavy loads.
4. Energy-Saving Advantages & Durability
ShuYi 75kW Variable Frequency Drive adjusts motor speed according to actual load demand, which can achieve 20-50% energy saving compared with traditional fixed-speed drive systems, especially in light-load working conditions.
It adopts an optimized heat dissipation structure, with a temperature-controlled fan to ensure stable operation even when running at full load for a long time. The working temperature range is -10℃ to 50℃, adapting to harsh industrial environments.
The enclosure is made of high-quality materials with anti-corrosion and anti-vibration performance, which can resist the erosion of dust, humidity and corrosive gas in industrial sites, extending the service life of the drive.
5. Why Choose ShuYi 75kW Variable Frequency Drive
ShuYi strictly tests each 75kW Variable Frequency Drive before leaving the factory, ensuring that it meets industrial quality standards and can operate stably in heavy-duty scenarios.
It supports multiple communication protocols, including Modbus RTU, which can be seamlessly integrated with existing industrial control systems, facilitating remote monitoring and parameter adjustment.
ShuYi provides professional technical support and after-sales service, including installation guidance, parameter debugging and fault troubleshooting, helping users maximize the performance of the drive.
