MEAN WELL VFD Series DC-Input Variable Frequency Drives
Product Features
The VFD series allows for precise speed control of AC induction motors and permanent magnet motors while utilizing a DC power input. Its fanless design and DIN-rail mounting make it a robust choice for smart control cabinets.
- DC-to-AC Motor Drive: Converts DC input into a variable voltage/frequency AC output, perfect for systems where only DC power (batteries/solar) is available.
- DIN Rail Mounting: Slim, space-saving design (TS-35/7.5 or 15) ideal for integration into standard industrial electrical enclosures.
- Fanless Design: Conduction-cooled construction ensures high reliability and eliminates noise associated with traditional cooling fans.
- Comprehensive Protection: Equipped with built-in safeguards including Short circuit, Overload, Over voltage, and Over temperature protection to protect both the drive and the motor.
- User-Friendly Interface: Designed for easy control, allowing for smooth acceleration and deceleration of connected motors.

Series Range Overview
| Model | DC Input | AC Output | Rated Power |
|---|---|---|---|
| VFD-150-110 | 24V/48V DC | 110VAC | 150W |
| VFD-150-230 | 24V/48V DC | 230VAC | 150W |
Note: These drives are specifically optimized for smaller AC motors used in pumps, fans, and small-scale automation equipment.
Application Suitability
The VFD series is a versatile solution for scenarios requiring AC motor movement without grid-connected AC power.
| Application Area | Typical Use Case |
|---|---|
| Mobile Systems | Controlling fan speeds in mobile vehicle ventilation or cooling systems. |
| Off-Grid Pumping | Managing flow rate in battery-powered or solar-powered pump applications. |
| Industrial Automation | Precise control of small AC motors in localized automated assembly stations. |
Selection Tip: Ensure that the motor’s rated power does not exceed 150W and that the drive's output AC voltage matches the motor's operating voltage. Because this drive manages motor start/stop, ensure proper cable shielding to minimize electromagnetic interference (EMI) with other nearby control electronics.
