Our General Purpose VFD Series offers a versatile, high-reliability solution for precision speed control of three-phase induction motors. Designed for both constant torque (Heavy Duty) and variable torque (Fan/Pump) applications, these inverters provide an ideal balance of performance, size, and cost-effectiveness.

Spanning a power range from 1.5kW to 7.5kW, this inverter series utilizes advanced Vector Control and V/F Control algorithms to deliver high starting torque and smooth operation even at low speeds. Whether you are seeking to reduce energy consumption in HVAC systems or improve precision in machinery, this drive is engineered for 24/7 industrial performance.

• Dual Rating Mode: Features selectable "G" (General/Heavy Duty) and "P" (Fan/Pump) ratings. This allows for higher overload capacity for machinery or optimized energy saving for centrifugal loads.

• Superior Starting Torque: Delivers 150% rated torque at 0.5Hz (in sensorless vector mode), ensuring reliable starts for fully loaded conveyors, mixers, and compressors.

• Advanced Energy Saving: Specifically optimized for fans and pumps, our VFD can reduce energy consumption by up to 30%–50% by matching motor speed exactly to system demand.

• Robust Multi-Protection: Includes 20+ protection features, including Over-current, Over-voltage, Under-voltage, Overheat, Phase Loss, and Short-circuit protection to safeguard both the drive and the motor.

• Built-in PID Controller: Perfect for closed-loop systems (e.g., constant pressure water supply or temperature control), eliminating the need for external PLC controllers in many applications.

1. Water Supply & HVAC: Constant pressure pumping and variable speed control for cooling tower fans and air handling units.

2. Conveyor & Logistics: Smooth acceleration and deceleration for belt systems to prevent product damage and mechanical wear.

3. Textile & Food Machinery: High-precision speed synchronization for processing lines and industrial mixers.

4. Plastic & Extrusion: Stable torque output for high-friction extrusion processes.

• User-Friendly Keypad: Equipped with a detachable digital operator with a parameter copy function, allowing for rapid commissioning of multiple drives.

• Compact "Book-Style" Design: Saves valuable space in electrical control cabinets, allowing for side-by-side installation with optimized airflow.

• High-Quality Components: Utilizes premium IGBT modules and long-life capacitors to ensure the drive withstands the thermal stress of industrial environments.

• Excellent EMC Performance: Built-in filters help reduce electromagnetic interference, ensuring the drive does not interfere with sensitive nearby electronics.

Q: Can this drive handle a 150% overload?

A: Yes. When set to G (Heavy Duty) mode, the drive is rated to handle a 150% overload for 60 seconds. For centrifugal fans and pumps, the P mode provides a more cost-effective rating with 120% overload capacity.

Q: Does it support remote control?

A: Absolutely. It features standard RS485 Modbus communication and multiple programmable digital/analog inputs for remote Start/Stop and frequency reference from a PLC or HMI.

Q: Is it difficult to program?

A: No. The drive comes with a "Quick-Start" parameter group that covers 80% of standard applications. For more complex needs, the comprehensive manual provides clear step-by-step guidance for vector tuning.
