- Optimized PID design, allowing for stable operation of the system and avoiding frequent load and unloading regulation at maximum;
- Real-time monitoring of overload degree of the air compressor, and display of overload alarm information;
- Automatic sleeping function, favorable for energy conservation and reducing equipment wearing;
- Able to detect various blocking signals, including air filter and oil filters, etc; timely alarming on LCD display, and clearing of alarm information via reset button;
- Multi-point temperature detection; with oil temperature detection channel, and 1-channel PT100 temperature detection channel, which can be also used for detection of motor’s internal temperature;
- Providing 1-channel independent 485 interface, which can be used for remote monitoring and control or for networking of multiple air compressors; Modification of relevant inverter parameters on LCD display screen (high integration);
- Real-time clock function, display of current time and recording of fault time, convenient for maintenance and inquiry.
- Having phase detection function and oil cooling fan current detection function, hence allowing for real-time display of the master motor’s working current; and having the motor overload and overcurrent protection function.
