ZFeng 900 Series 560Kw-T-P General Vector Variable Frequency Drive
High power frequency converters are key equipment used in the industrial field for efficient regulation of motor speed and energy conservation. They typically have a power range of several hundred kilowatts to several megawatts and are widely used in industries such as power, metallurgy, petrochemicals, mining, cement, and papermaking. Its core function is to precisely control the operation of three-phase asynchronous motors or synchronous motors by changing the power frequency and voltage, meeting the speed regulation requirements under complex working conditions.
FEATURES
High power density and reliability
Adopting advanced high-power IGBT (Insulated Gate Bipolar Transistor) or SiC (Silicon Carbide) power modules, it has high switching frequency and low loss characteristics.
Optimization of heat dissipation design (such as water cooling or forced air cooling) to ensure long-term stable operation.
Wide voltage and frequency range
The input voltage usually covers the range of 3kV to 10kV, and the output frequency can be adjusted within a wide range (such as 0-500Hz) to meet the needs of different motors.
High performance control algorithm
Support advanced algorithms such as Vector Control (FOC) and Direct Torque Control (DTC) to achieve high-precision torque and speed control.
Built in PID regulator, which can be linked with the upper computer system to achieve closed-loop control.
Multiple protection functions
Comprehensive protection against overload, overvoltage, undervoltage, overcurrent, overheating, grounding faults, etc., extends equipment life.
Fault self diagnosis and alarm function, easy to maintain quickly.
Communication and integration capabilities
Supports industrial bus protocols such as Profibus, Modbus, CANopen, EtherCAT, etc., achieving seamless integration with PLC, DCS and other systems.
Optional HMI (Human Machine Interface) or remote monitoring function can be selected to enhance operational convenience.
Energy conservation and economic benefits
Variable frequency speed regulation energy-saving: By matching the motor speed with the load demand, the phenomenon of "big horse pulling small car" is avoided, and the energy-saving rate can reach 20% -50%.
Soft start function: reduces the impact of motor starting current on the power grid and extends equipment life.
Process optimization: Accurately control equipment operating parameters to improve product quality and production efficiency.
