High Density 0.75KW~7.5KW Mini VFD Inverter 3 Phase 380V For Fans And Water

The Mini Series Universal VFD is a high-performance, space-saving Variable Frequency Drive engineered specifically for the precision control of three-phase asynchronous motors. Available in power ratings from 0.75kW to 7.5kW, this series bridges the gap between bulky industrial drives and the need for compact, efficient automation.

Optimized for Fans and Water Pumps, this inverter utilizes advanced control algorithms to provide high starting torque and smooth speed regulation. Its "Book-style" narrow design allows for side-by-side installation, making it the premier choice for OEMs and panel builders who need to maximize space in compact control boxes while maintaining professional-grade motor protection.

•    High-Density Compact Design: Engineered with a smaller footprint than standard industrial inverters, reducing cabinet space requirements by up to 30%.

•    Integrated PID Logic: Ideal for constant pressure water supply or temperature-controlled ventilation. Simply connect a pressure/temperature sensor for fully automated closed-loop control.

•    Superior Energy Savings: By adjusting motor speed to match actual demand, this VFD can reduce power consumption by 30% to 50% in centrifugal load applications.

•    Enhanced Motor Protection: Built-in safeguards against over-voltage, under-voltage, short-circuits, and motor thermal overloads, ensuring 24/7 operational reliability.

•    User-Friendly Keypad: Features an intuitive digital display and an integrated speed potentiometer for instantaneous manual frequency adjustment.

1. Small Pumping Systems: Managing constant pressure for residential booster pumps, garden irrigation, and small-scale livestock watering.

2. Commercial Ventilation: Controlling exhaust fans and air blowers in kitchens, workshops, and greenhouses to optimize air quality and noise.

3. Light Machinery: Providing variable speed for conveyor belts, packaging machines, and woodworking tools like sanders or small lathes.

4. HVAC Maintenance: Retrofitting fixed-speed fan motors in air handling units (AHUs) to improve energy efficiency and comfort levels.

• Silent Carrier Frequency: Adjustable up to 15kHz to eliminate the high-pitched "motor whine" common in lower-quality inverters—perfect for indoor or noise-sensitive areas.

• Tough Industrial Build: The internal PCB is treated with an anti-corrosion, anti-dust conformal coating, ensuring stability in humid pump rooms or dusty workshops.

• Precision Speed Accuracy: Digital frequency resolution of 0.01Hz allows for ultra-fine adjustment of motor RPM for delicate industrial processes.

• RS485 Connectivity: Ready for Industry 4.0, allowing you to link multiple drives to a central PLC or HMI for synchronized automation.

Q: Is this VFD difficult to program for a simple water pump?

A: Not at all. The unit comes with factory-default settings for standard 380V motors. For most pump applications, you only need to wire the power and adjust the speed via the front knob.

Q: Can I use this for a 2.2kW motor if I buy the 7.5kW version?

A: Yes. Using a higher-rated VFD is perfectly safe and actually provides a larger safety margin. You simply enter your motor's specific current data into the parameters for optimal protection.

Q: Does it support external start/stop switches?

A: Absolutely. The terminal block includes multi-function digital inputs (X1-X4) that allow you to connect external buttons, float switches, or pressure switches for remote control.
