Product feature

1. Air compressor dedicated logic

Omits the traditional PLC control scheme, built-in pressure and temperature dual PID control, more intelligent control, more 

convenient wiring, and simpler debugging.


2. Air compressor dedicated human-machine interface

High-performance air compressor dedicated touch screen, high-end and atmospheric screen, sensitive touch response, adaptive 

air compressor control program, easy to operate.


3. Multi-function expansion card

Optional multi-function expansion card, support for the expansion of application functions such as oil-free water lubrication, built-in 

oil-free water lubrication application macro, no need for cumbersome PLC programming, one-click debugging can be achieved.


4. Excellent performance

Advanced vector control algorithm, cooperate with many mainstream motor manufacturers in the industry, optimize product adaptability, 

adjust the best performance output, and improve system operation reliability; the inverter is compatible with asynchronous/synchronous 

motor control.


5. Reliable and safe protection

For various harsh applications of air compressors, it provides high overload service coefficients, configures EMC filters, and sets a 

variety of warning and protection functions to reduce the probability of failure during user use.
