Basic Functions

Optimize Feeding:

• Adjust frequency for smoother, quieter operation and energy-saving feeding.

Automatic Voltage Control:

• Eliminate speed changes due to power fluctuations with built-in digital voltage regulation.

Gentle Start-up:

• Protect vibration plate with preset slow voltage increase during start-up.

Sensor Control:

• Implement full/empty shutdown using NPN, PLC, or photoelectric sensors.

Remote Speed Control:

• Adjust output voltage remotely with potentiometer, PLC, or 1~5V signal.

DC Control Output:

• Drive equipment like solenoid valves with DC low-voltage control signal.

Lock Function:

• Prevent accidental operation with long press on/off key lock.

Maximum Voltage Limit:

• Set maximum voltage to avoid equipment damage.

Overheat Protection:

• Shuts down output to prevent overheating for safe operation.

Overcurrent Protection:

• Stops output to safeguard controller and equipment from damage.

Recoverable Short Circuit:

• Protect controller and equipment during short circuits with automatic recovery.
