INVT GD10 GD20 Mini VFD | Compact Low Frequency Inverter for Industrial Fan Pump Energy Saving
Frequently Asked Questions
How is the heat resistance? Can it be used in high-temperature areas?
Working temperature ranges from -10℃ to 40℃. An extra cooling fan ensures stable operation in hot tropical regions.
Can it adapt to overseas non-standard 380V / 415V power grids?
Yes. It adopts a wide voltage design and works well with 380-440V global power supplies.
The motor lacks power and cannot carry loads during startup. What should I do?
Increase the startup torque parameters. For heavy loads, choose the GD20 vector model for stronger performance.
Why does the motor make loud noise and shake while running?
Adjust the carrier frequency and acceleration/deceleration time to eliminate most jitter and noise issues.
Will the VFD interfere with nearby sensors or controllers?
It comes with standard EMC protection. Add magnetic rings for long motor cables to reduce interference.
Is an external braking resistor required for overseas installation?
Not needed for fans and water pumps. It is mandatory for fast stop or lifting equipment.
Can it connect with external PLC for start/stop and speed control?
Yes. It supports terminal control and communication, easy to wire and connect with mainstream PLC brands.
Is it easy to damage in dusty and humid factory environments?
Standard IP protection for regular use. The conformal coating version is recommended for moisture and dust resistance.
How to choose between GD10 and GD20 with the same power rating?
Choose GD10 for lower cost; pick GD20 for higher torque and more stable operation.
What is the warranty period? Is after-sales maintenance easy overseas?
Standard 18-month warranty. Universal spare parts and simple structure make overseas repair and replacement convenient.
