The Zoncn Z2400-5R5G is a 5.5kW, 380V 3-phase vector inverter designed for air compressor applications. With Sensorless Flux Vector Control (SFVC) and V/F control dual modes, it delivers high starting torque, precise speed regulation, and stable operation under variable air demand.
It is an ideal VFD solution for air compressor manufacturers, system integrators, and industrial maintenance teams looking for reliable motor control, Modbus communication, and compact panel installation.
High starting torque ensures reliable startup under loaded compressor conditions.
SFVC vector control maintains stable speed and torque as air demand changes.
Built-in PID supports closed-loop pressure control without extra controllers.
RS485 / Modbus-RTU enables PLC, HMI, SCADA, and remote monitoring integration.
Strong overload capacity handles frequent peak loads in industrial use.
Compact IP20 design saves cabinet space and simplifies maintenance.
Dual Control Modes
Supports SFVC and V/F control. Vector mode provides precise speed and torque regulation; V/F mode offers simple, reliable operation.
High Starting Torque
In SFVC mode, G-type rating delivers 150% rated torque at 0.5 Hz, ensuring reliable heavy-duty startup.
Strong Overload Capacity
G-type operation: 150% rated current for 60 seconds; 180% rated current for 3 seconds.
Wide Speed Range & High Accuracy
Achieves 1:100 speed control range with ±0.5% speed stability accuracy in SFVC mode.
Wide Output Frequency
0–320 Hz in vector mode and 0–3200 Hz in V/F mode.
Note: 0–3200 Hz is intended for high-speed spindles/special motors only. Standard motors must run within nameplate frequency.
Built-in PID & RS485 Communication
Onboard PID enables closed-loop process control. Standard RS485 with Modbus-RTU supports remote monitoring and parameter adjustment.
Auto Voltage Regulation (AVR)
Maintains stable output voltage during mains fluctuations for reliable motor operation.
Compact & Easy to Install
Space-saving structure with removable control panel. IP20 protection for cabinet installation.
