Sdvc311-s（1.5a）variable Frequency Digital Controller For Vibratory Feeder

Frequency Adjustment: The Output frequency of the controller can be manually adjusted to the resonant frequency of the vibratory feeder to get

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/Shutdown: During startup or shutdown, the output voltage will gradually change to avoid sudden shock. Soft

start/shutdown time can be digitally preset.

Switch Sensor ON/OFF Control: An Adaptive 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: The Output Voltage of the controller can be adjusted remotely by an external potentiometer, a PLC, a 1- 5V DC signal, or a 4A 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 

external devices.

Keypad Lock: Lock all buttons on the keypad to prevent misoperation by pressing the ON/OFF button and holding for 2 seconds.

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.

Over/Under-Voltage Protection: When the input voltage is too high/low, the power supply will be automatically turned off for self-protection

Restorable Short Circuit Protection: If the 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. When there is no short circuit at the output side, the controller will function again after being powered on
