3-Amp Variable Frequency Intelligent Control

Automatic Constant Feed Speed Control: Automatic output voltage adjustment in real-time to ensure constant preset feed speed regardless of weight change of the workpieces.

Automatic Frequency Adjustment: Automatic output frequency adjustment in real time to make sure the load is always working at its resonant frequency.

Automatic Resonant Frequency Search: Search out and output resonant frequency of the load. Other related parameters are also set automatically.

RS485 Communication: All parameters of the controller can be adjusted via RS485. 

Automatic Switch Sensor Type Recognition: The controller can recognize and adapt to both PNP and NPN type switch sensors.

Sync Output: Sync output waveform of the slave controller with that of the master controller to the same frequency and phase to avoid cross talk.  

Overvoltage Protection: If input voltage is too high, power supply of the controller will be shutdown automatically to protect itself.

Digital Overheat Protection: If internal temperature of the controller gets too high the controller will stop its output to protect itself.

Current Overload Protection: If output current exceeds its rated value the controller will stop its output to protect itself and the load.

Restorable Short Circuit Protection: If output of the controller is short-circuited, the controller will shut down its output to protect itself and the load but the fuse inside will not be blown. So when there is no short-circuit at the output side, the controller will work again after it is powered on.
