This converter is a general-purpose AC variable frequency drive designed for speed control of three-phase AC motors. It focuses on stable operation, clear parameter settings, and practical on-site use, making it suitable for fans, pumps, and standard industrial equipment.

• Designed for standard industrial applications without over-configuration
• Clear operation logic for easier installation and commissioning
• Suitable for long-term, stable operation
• Easy integration into existing systems

• Supports V/F control for common loads such as fans and pumps
• Sensorless vector control available for improved low-speed stability
• Adjustable acceleration and deceleration times to reduce mechanical stress
• Smooth frequency output for controlled operation

• Multiple frequency setting methods: keypad, analog input, communication
• Multi-speed operation for basic process control
• Built-in PID function for constant pressure or flow applications
• Programmable I/O terminals for flexible system configuration

To enhance system reliability, the inverter includes standard protection functions:

• Overcurrent protection
• Overvoltage / undervoltage protection
• Overload protection
• Overtemperature protection
• Operational fault detection

• Water supply, pumps, and booster systems
• Fans, ventilation, and air handling systems
• Conveyors and light-duty transport equipment
• Packaging, food processing, and light industry machinery
• General industrial automation systems

• Input Voltage: Three-phase AC 380V (±15%)
• Output Frequency: 0 – 400 Hz
• Control Modes: V/F control, vector control
• Frequency Resolution: 0.01 Hz (digital)
• Cooling Method: Forced air cooling
• Installation: Wall-mounted or cabinet installation

The converter should be installed in a well-ventilated environment free from excessive dust or corrosive gases. Wiring and commissioning should be carried out by experienced personnel in accordance with local electrical standards.
