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.
