Feature: 1. Low Noise: The carrier frequency is continuously adjustable from 1.0KHz to 16.0KHz, which minimizes motor noise. 2. Automatic Voltage Regulation: Dynamic voltage regulation, static voltage regulation and non-voltage regulation can be selected according to requirements. 3. Low Frequency and High Torsion: The starting torsion is twice the rated torsion and the constant torsion is output within 50Hz. 4. Four Advantages: Soft start soft stop, energy saving, protection motor, stepless speed regulation. 5. Multi-segment Operation: 16-segment programmable multi-speed control. Multiple operating modes are available. 6. Simple PLC Operation: Can set up to 16-segment speeds to run automatically, and the running time of each segment can be set. 7. RS485 Communication: Multiple communication protocols are optional, with linkage synchronization control function. 8. Output Frequency Range: Wide range, low frequency mode: 0-300Hz; high frequency mode: 0-3000Hz. 9. PID Control: Widely used in constant pressure water supply, wind pressure constant pressure control, etc. 10. Built-in Brake Unit. 11. Protection Functions: Overload protection, overheat protection, overvoltage protection, overcurrent protection, undervoltage protection, phase loss protection, grounding protection, short circuit protection, stall protection, flame retardant/moisture proof/anti-corrosion/anti-salt fog.
