The AD800-4T0.75GB Series is a high-performance vector control variable frequency drive (VFD) specifically tailored for applications such as water pumps and extruding machines. With a power range from 0.75KW to 400KW, this 380V VFD is designed to meet the demands of heavy-duty industrial environments.

Key Features of the AD800-4T0.75GB Series VFD:

1. Power and Control:
   • The VFD operates on a three-phase 380V ±15% input voltage and offers both open-loop vector control and V/F control.
   • It provides a substantial starting torque of 180% at 0.5Hz and a torque response time of less than 20ms for open-loop vector control and less than 5ms for closed-loop vector control.
2. Protection and Safety:
   • Equipped with up to 25 fault protection functions, including overcurrent, overvoltage, undervoltage, overtemperature, phase loss, and overload protection, ensuring reliable and safe operation.
3. Cooling and Installation:
   • Features a forced air cooling system to maintain optimal operating temperatures.
   • Versatile installation options with both wall-mounted and cabinet styles available.
4. Advanced Functionality:
   • The VFD supports a wide range of frequencies up to 4000Hz for high-frequency control and offers a frequency resolution as fine as 0.01Hz.
   • It includes an automatic voltage regulator (AVR) to maintain stable output voltage even when the grid voltage fluctuates.
5. User Interface and Support:
   • The VFD comes with a friendly user interface that displays a welcoming “HELLO” message upon power-up.
   • It supports multiple encoder types and offers a multifunctional JOG button for easy operation.
6. Environment and Durability:
   • Suitable for indoor use in environments free from direct sunlight, dust, corrosive gases, and flammable substances.
   • Designed to operate in temperatures ranging from -10°C to +40°C with a relative humidity below 95% RH.
7. Documentation and Support:
   • Comprehensive user manuals and technical documentation are available for download, ensuring easy setup and maintenance.

The AD800-4T0.75GB Series VFD is not just a variable frequency drive; it’s a testament to our commitment to providing advanced, reliable, and user-friendly solutions for industrial applications. For more information or to download the user manual, visit our website today.
