An industrial control device specifically designed for air compressors, enabling stable air pressure, energy savings, and equipment protection through motor speed regulation.

Stable Air Pressure Control

Adopts PID closed-loop control technology to monitor supply pressure in real time and automatically adjust motor speed, eliminating pressure fluctuations caused by frequent loading/unloading in traditional fixed-frequency machines.

Energy Efficiency

Reduces energy consumption by lowering motor speed. Saves 10–20% during loaded operation and ~10% during unloaded operation, with overall energy savings of 20–60%.

Principle: Motor power is proportional to the cube of speed (e.g., 50% speed reduction reduces power to 12.5%).

Soft Start & Equipment Protection

Limits starting current (<2× rated current), avoiding grid and mechanical shocks, extending motor lifespan by >30%.

Reduces valve wear from frequent switching, lowering maintenance costs.

Multi-Motor Compatibility

Supports asynchronous motors and custom synchronous motors (SPMSM/IPMSM) across a 7.5–415kW power range.

Advanced Control Technology

Utilizes VVC+ vector control or SPWM/SVPWM techniques to optimize switching losses and harmonic content, with a power factor >0.95.

Wide Voltage & Overload Capacity

Input voltage range: -20% to +10%. Models ≥37kW integrate DC reactors to enhance power factor and suppress harmonics.

Overload capacity: 150% rated current for 1 minute, 200% instantaneous for 1 second.

Intelligence & Communication

Built-in MODBUS/CANOPEN interfaces for remote monitoring and parameter adjustment.

Real-time display of current, voltage, and frequency on the operation panel; optional COPY card for rapid parameter cloning.

Environmental Adaptability

Operating temperature: -10°C to 50°C (derated for 40–50°C), IP20 protection, dust/moisture-resistant design.

Pharmaceutical Industry

Precisely controls gas flow, pressure, and temperature to meet cleanliness requirements for drug packaging and filling.

Electronics Industry

Provides high-quality gas for semiconductor and precision component production, ensuring stable air supply.

General Industrial Scenarios

Replaces traditional fixed-frequency machines, reducing floor space and enabling compact piping layouts.

Power Matching: Select based on motor power, reserving 20% margin for overload demands.

Control Requirements: Prioritize closed-loop models

Environmental Adaptability: Choose derated models

Communication & Scalability: Opt for MODBUS/CANOPEN-compatible models for remote monitoring needs.
