New Original High Quality Invt Brand 185 kW 380V VFD Inverter GD300-01A-185G-4
GD300-01A series air compressor dedicated inverter is a product customized and developed by INVT for the application requirements of the air compressor industry. It can be used for the control of synchronous or asynchronous air compressors. The product supports optional multi-function expansion cards and is suitable for air compressor control with more functional requirements.
Power range:
Three-phase 220V (-15%) ~ 240V (+10%) 7.5 ~ 185KW
Three-phase 380V (-15%) ~ 440V (+10%) 7.5 ~ 500KW
Three-phase 520V (-15%) ~ 690V (+10%) 22 ~ 630KW
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 coefficient, configures EMC filters, and sets a variety of warning and protection functions to reduce the probability of failure during user use.
