ZFeng 310 Series 0.75Kw General Vector Variable Frequency Drive
General vector frequency converter is a power electronic device that controls the speed by adjusting the power supply frequency of the motor, and its core is vector control technology. This technology decomposes the stator current of the motor into excitation component and torque component, and controls the magnetic field and torque separately, achieving control accuracy comparable to DC motors.
The ZF310 series is a new generation of general-purpose variable frequency drive independently developed by our company, dedicated to meeting the high-performance variable frequency control requirements of low-power range asynchronous AC induction motors. The product is suitable for single-phase 220V or three-phase 380V, using space voltage vector control technology and DSP control system to enhance the reliability and stability of the product. It has excellent acceleration and deceleration performance and fast dynamic response, adapts to high temperature, high humidity, dust and other application sites. At the same time, the book style design saves installation space.
Key Features:
- Precise Speed Regulation: Speed control error as low as ±0.5%, meeting diverse operating condition requirements.
- Energy-Efficient Operation: Dynamically adjusts output power based on load, with energy-saving efficiency of approximately 10%-50%.
- Rapid Response: Real-time tracking of command changes, dynamic response speed improved to millisecond level.
- Motor Protection: Built-in overcurrent, overvoltage, and overheating protection, extending equipment lifespan.
Application
- Mechanical manufacturing: CNC machine tools, cranes, conveyor belts to improve machining accuracy and efficiency.
- Metallurgical industry: rolling mills, steelmaking furnaces, achieving efficient and energy-saving operation.
- Chemical industry: pumps, fans, compressors, precise control of flow and pressure.
- Power industry: auxiliary equipment speed regulation, optimizing power system energy efficiency.
- Other industries: textile, papermaking, food processing, and other scenarios that require speed control.
Selection and Precautions
- Power matching: The rated power of the frequency converter should be ≥ the rated power of the motor, with a reserved margin of 10% -20%.
- Load type: For constant torque loads (such as cranes), high overload capacity models should be selected.
- Environmental adaptation: High protection level products should be selected for harsh environments (humid, dusty).
- Function extension: Select advanced functions such as integrated PID control and communication interface (Modbus/CANopen) according to requirements.
- The maximum operating altitude of the 0.4~3kW drive during 2000m. If it needs to be used in high-altitude areas, please contact us for customization.
