1.      Automatic High Precision Voltage Regulation: The internal digital voltage regulation circuit can eliminate feed speed variation caused by mains voltage fluctuation.

2.      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.

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

4.      Overcurrent Protection: if output current exceeds its rated value, the controller will stop its output to protect itself and the load.

5.      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.

6.      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.

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

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

1. Max Adjustable Output Voltage：Output Voltage of the controller can be adjusted remotely by an external potentiometer, a PLC, or a 1-5V DC signal.
2. 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.
3. Preset Speeds: 6 feed speeds can be preset, stored and outputted by connecting external short-circuit signals.
4. Dual Switch Sensor ON/OFF Control：2 NPN switch sensors or PLCs can be connected to turn on/off the controller.
5. Automatic Frequency Adjustment：Automatic output frequency adjustment in real time to make sure the load is alwary working at its resonant frequency.
6. 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.
7. Automatic Resonant Frequency Scan：Scan and then output resonant frequency of the load. Other related parameters are also set automatically.
8. Automatic Switch Sensor Type Recognition：The controller can recognize and adapt to both PNP and NPN type switch sensors.
9. Sync Output：Sync output waveform of the slave controller with that of the master controller to the same frequency and phase to avoid beat effect.
10. Counting：Count number of the workpieces. The controller will slow down or stop when count up to preset value. (available on SDVC34-MJ & SDVC34-MRJ)
11. RS485 Communication：SDVC34-MR、SDVC34-MRJ）All parameters of the controller can be adjusted via RS485 (available on SDVC34-MR &SDVC34-MRJ)
