Product features 1

● Frequency Adjustment: 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 power on to avoid sudden shake.  Soft start time can be digitally preset.

● Switch Sensor ON/OFF Control: Support NPN/PNP sensors or PLC remote full/empty shutdown control.

● 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 ON/OFF Control of the controller to drive a solenoid or other external devices.

Product features 2

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

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

● Overcurrent 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 power on.

● Max Adjustable Output Voltage: Max Adjustable Output Voltage can be preset to protect the load from damage caused by voltage that is too high.

SDVC34 series

Automatic Constant Feed Speed Control,Automatic Frequency Adjustment,Automatic Resonant Frequency Search,Counting,

Rs485 Communication,Sync Output,Overvoltage Protection,Digital Overheat Protection,Overcurrent Protection,Restorable Short Circuit Protection

Product features 1

● Automatic Constant Feed Speed Control: Automatic output voltage adjustment in real-time to ensure constant preset feed speed regardless of the 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 the resonant frequency of the load. Other related parameters are also set automatically

● Counting: Count the number of workpieces. The controller will slow down or stop when counting up to the preset value.  

● RS-485 Communication: All parameters of the controller can be adjusted via RS-485

● Automatic Switch Sensor Type Recognition: The controller can recognize and adapt to both PnP and nPn type switch sensors.

Product features 2

● Sync Output: Sync the output waveform of the slave controller with that of the master controller to the same frequency and phase to avoid the beat effect.

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

● 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, it 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 the power is on.
