CE certificated, RoHS compliant. Frequency Adjustment: The output frequency of the controller can be manually adjusted to the resonant frequency of the vibratory feeder to get a smooth, quiet, and energy-saving feed effect. Automatic High Precision Voltage Regulation: The internal digital voltage regulation circuit can eliminate feed speed variation caused by mains voltage fluctuation. Time Adjustable Soft Start: The controller will gently increase output voltage from 0 to the preset value when powered on to avoid sudden shaking. Soft start time can be digitally preset. Switch Sensor ON/OFF Control NPN switch sensor or PLC can be connected to turn on/off the controller. Photoelectric Sensor ON/OFF Control: The CUH Intelligent Photoelectric Sensor can be connected to turn on/off the controller. Remote Speed Control: Output Voltage of the controller can be adjusted remotely by an external potentiometer, a PLC, or a 1-5V DC signal. DC Control Output: The controller can output low voltage DC power associated with the ON/OFF Control of the controller to drive a solenoid or other external devices. Keypad Lock: Lock all buttons on the keypad to prevent misoperation by pressing the ON/OFF button and holding for 2 seconds. Digital Overheat Protection: If the internal temperature of the controller gets too high, the controller will stop its output to protect itself. Overcurrent Protection: If the output current exceeds its rated value, the controller will stop its output to protect itself and the load. Restorable Short Circuit Protection: If the controller's output is short-circuited, the controller will shut down its production 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 power is on. Max Adjustable Output Voltage: Max Adjustable Output Voltage can be preset to protect the load from damage caused by a voltage that is too high.
