Variable Frequency Drive (VFD) Inverter | 0.75kW-800kW Industrial Motor Controller
Industrial VFD variable frequency drive with vector control, energy saving, full protection for fan, pump, conveyor and CNC machine. CE RoHS certified, 18-month warranty, OEM available.
Product Overview
Our industrial Variable Frequency Drive (VFD / Inverter) is a professional motor speed control solution designed for industrial automation equipment. Adopting advanced vector control technology, this VFD supports both induction motors and permanent magnet synchronous motors, delivering precise speed and torque regulation, smooth soft start and stop, and comprehensive operational protection.
Widely applicable to fans, water pumps, conveyors, compressors, mixers, machine tools, HVAC and water treatment systems, our VFD drives effectively reduce motor energy consumption, extend equipment service life, and lower overall operational costs. All models are fully certified with CE and RoHS, ensuring stable and reliable performance for global industrial projects.
Core Product Advantages
1. Outstanding Energy Saving & Cost Reduction
Built-in intelligent ECO energy-saving algorithm automatically optimizes output current under light-load conditions, avoiding unnecessary power loss. For fan and pump variable-torque loads, the VFD can save 25%-50% electricity with an average cost recovery period of 6-12 months. It eliminates strong current impact caused by direct motor start, stabilizes grid voltage, and greatly reduces long-term industrial power expenses.
2. Precise & Stable Vector Control
Supports V/F control, open-loop and closed-loop vector control modes to match different industrial load demands. The speed adjustment range covers 0.01Hz to 400Hz with a steady speed accuracy of ±0.5%. It achieves ultra-fast torque response within 5ms and maintains 100% rated torque at low speed without stalling. The universal G/P dual-mode design adapts to both constant-torque and variable-torque loads for versatile industrial scenarios.
3. Full Protection & High Durability
Equipped with complete protection functions including over-voltage, under-voltage, over-current, overload, over-temperature, short circuit, ground fault and stall prevention. Adopts industrial-grade three-proof coating, independent heat dissipation air duct and anti-vibration glue dispensing technology, realizing excellent dustproof, moisture-proof and anti-vibration performance. The drive works stably in a wide temperature range of -10℃ to +50℃, suitable for harsh factory and outdoor working environments. Optional STO safety torque off function meets SIL3 safety standards to protect equipment and personnel.
4. Easy Installation & Intelligent Debugging
Compact book-type structure saves installation space and supports vertical standard cabinet installation. Equipped with a clear LCD operation panel for visualized parameter setting and real-time data monitoring, enabling quick debugging for novice operators. Standard built-in Modbus RS485 communication supports remote control and system docking; optional expansion modules for Profinet, CANopen and EtherNet/IP are available. One-click motor self-learning function automatically matches motor parameters, eliminating complex manual calculation.
5. Global Certification & Reliable After-sales Service
All VFD models passCE and RoHS certification, complying with international industrial safety and environmental standards. We provide 18-month long warranty and lifelong professional technical support. The full power range from 0.4kW to 500kW covers most industrial motor equipment. Custom OEM and ODM services are supported, including private logo customization, boot interface modification, program customization and personalized packaging.
