IP54 Industrial Low Voltage VFD Variable Frequency Drive Single Phase

ZF310 Series Industrial Production Specific Low-voltage Variable Frequency Drive

Industrial production specific low-voltage frequency converter is a frequency converter designed for specific application scenarios and load characteristics in industrial production, which can meet the strict requirements of industrial equipment for speed regulation, energy saving, accuracy, and reliability.

FEATURES

• High protection level
  The industrial production environment is complex and may contain dust, moisture, corrosive gases, etc. Specialized frequency converters typically have protection levels of IP54, IP55, or even higher to ensure stable equipment operation. For example, in metallurgical, chemical and other scenarios, high protection levels can prevent dust and moisture from entering, extending equipment life.
• Wide voltage input range
  The voltage fluctuation in industrial power grids is significant, and specialized frequency converters typically support input voltage ranges of 380V ± 20% or even wider, adapting to the power supply conditions of different industrial sites.
• High performance control algorithm
  For industrial load characteristics such as fans, water pumps, winding machines, etc., vector control (FOC) or direct torque control (DTC) technology is adopted to achieve high-precision speed and torque control.
  For example, in textile machinery, vector control can ensure stable yarn tension and improve product quality.
• Quick response and overload capability
  In industrial production, frequent load changes require frequency converters to have fast dynamic response capabilities (such as accelerating/decelerating within 0.1 seconds) and overload capacity of 150% or even 200%.
• Multi machine synchronization and coordinated control
  In continuous production lines such as papermaking, printing, and packaging, multiple frequency converters need to operate synchronously. Specialized frequency converters support master-slave control, electronic gear synchronization, and other functions.
• Built in industry-specific features
  Integrate specific functions to meet the needs of different industries:
  Fan/water pump industry: PID regulation, sleep function, high-speed start, etc;
  Lifting industry: anti roll control, zero speed hovering, pre excitation, etc;
  Textile industry: swing frequency control, roll diameter calculation, yarn breakage detection, etc.

Customer Suggestion - Key Selection Points

• Load characteristic matching
  Select the appropriate frequency converter model based on the load type (constant torque, constant power, square torque). For example, fans and water pumps should use V/F control frequency converters, while winding machines and machine tools need to use vector control frequency converters.
• Power and current capacity
  The rated power of the frequency converter should be greater than 1.2-1.5 times the rated power of the motor, and the overload capacity should meet the peak load demand.
• Communication and Scalability
  Supports mainstream industrial bus protocols such as Modbus, Profibus, EtherCAT, etc., making it easy to integrate with systems such as PLC and DCS.
