Compact Mini Variable Frequency Drive (VFD Inverter)

Product Overview

This mini series variable frequency drive is a compact, cost-effective motor control device dedicated to speed regulation, soft start and energy optimization of 3-phase asynchronous motors. It converts fixed-voltage fixed-frequency single-phase mains power into adjustable-frequency adjustable-voltage 3-phase output, allowing continuous stepless speed control of standard induction motors even in single-phase power supply scenarios.

It adopts advanced IGBT power modules and vector control algorithm, delivering high starting torque, stable speed regulation and excellent load adaptability. The front panel integrates a high-brightness LED digital display, function keypad, speed adjustment potentiometer and dedicated RUN/STOP buttons, enabling intuitive on-site operation and parameter configuration. Built-in comprehensive protection mechanisms safeguard both the drive and the connected motor against electrical faults and abnormal operating conditions. With a space-saving form factor and standard DIN-rail mounting, it is ideal for installation in small control cabinets, machinery equipment and automated production lines. It is widely applied in water pumps, fans, blowers, conveyors, small machine tools, packaging machinery and HVAC systems for process optimization and energy efficiency improvement.

Key Product Features

FAQ

Q1: What is a variable frequency drive (VFD / inverter) used for?

A: A VFD controls the speed and torque of 3-phase AC motors by adjusting the frequency and voltage of the power supply. It enables energy savings on pumps and fans, soft starting to reduce mechanical shock, and precise speed control for production processes.

Q2: Can this single-phase input inverter drive a 3-phase motor?

A: Yes. It accepts single-phase 220V AC input and converts it to variable-frequency 3-phase output, so you can operate a standard 3-phase induction motor even with only single-phase mains power available.

Q3: How can I control the motor speed?

A: You can adjust speed directly via the front panel potentiometer knob, program multi-speed presets via the keypad, or control remotely via external analog signal (0-10V / 4-20mA) or multi-function terminal inputs.

Q4: What protection functions does this inverter have?

A: It integrates full electrical and thermal protection including over-current, over-voltage, under-voltage, overload, over-heat, phase loss and short circuit protection. Fault codes are displayed on the LED panel for quick troubleshooting.

Q5: How is this inverter installed?

A: It supports standard 35mm DIN rail mounting for quick snap-in installation in control cabinets, and can also be wall-mounted with screws. Its compact size is ideal for small electrical panels and machine integration.

Q6: Do you support OEM private label service?

A: Yes, we support custom logo printing on the front panel and custom packaging. A certain minimum order quantity applies for OEM service.

Q7: What power ratings are available in this series?

A: Standard models cover 0.75kW, 1.5kW and 2.2kW. Custom power specifications and voltage versions can also be developed for volume project requirements.
