3-Amp Digital Variable Voltage Control

Frequency Adjustment: Output frequency of the controller can be manually adjusted to 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 voltage fluctuation.

Time Adjustable Soft Start: The controller will gently increase output voltage from 0 to the preset value when power on to avoid sudden shake. Soft start time can be digitally preset.

Switch Sensor ON/OFF Control: 1 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 SDVC31-M can be controlled by an external potentiometer, a PLC, or a voltage control signal ranging from 1V to 5V.

DC Control Output: The controller can output low voltage DC power associated with on/off control of the controller to drive a solenoid or a 4-20mA current signal.

Keypad Locking: Lock all buttons on the keypad to prevent misoperation by pressing the on/off button and hold for 2 seconds.

Overheat Protection: The controller will halt its output to protect itself when operating temperature is too high.

Current Overload Protection: The SDVC31-M will halt its output to ensure equipment operation safety when operating current exceeds its rated value.

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.
