ZFeng 900 Series 630Kw-T-P General Vector Variable Frequency Drive

The frequency converter is mainly composed of a microprocessor unit that rectifies (AC to DC), filters, inverters (DC to AC), braking units, driving units, and detection units. Its core working principle is to adjust the voltage and frequency of the output power supply by disconnecting the internal IGBT (Insulated Gate Bipolar Transistor), and provide the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation.

• Speed control: The frequency converter can accurately adjust the speed of the motor to meet the operating requirements under different working conditions.
• Energy saving and consumption reduction: By adjusting the operating frequency of the motor to run as needed, unnecessary energy waste can be avoided.
• Overload protection: Real time monitoring of the motor's load condition, providing protection in case of overload or malfunction to prevent motor damage.
• Soft start and smooth operation: With the soft start function, the motor can start smoothly, reducing the impact and power grid pressure changes during startup.
• Remote monitoring and fault diagnosis: Some advanced frequency converters are equipped with remote monitoring and fault diagnosis functions, which facilitate real-time monitoring of equipment operation status.

• Air conditioning load class: used for central air conditioning systems such as refrigeration pumps, chilled water pumps, fans, etc., to achieve energy savings.
• Crusher type load: Used for speed regulation of crushers, ball mills, and other equipment in the metallurgical mining and building materials industries.
• Compressor load: Used for speed regulation of various compressors in industries such as steel, mining, and fertilizer.
• Fan and pump loads: Energy saving and reduced mechanical wear can be achieved through variable frequency speed regulation.
• Elevator and crane loads: Improve the reliability and dynamic characteristics of the drag system.
• Injection molding machine load: By variable frequency speed regulation, energy consumption is reduced and production efficiency is improved.
• Environmental Protection Load: Used for controlling environmental protection equipment such as industrial wastewater treatment and garbage power plants.
