Whether you’re an OEM manufacturer, system integrator, or industrial equipment builder, this VFD ensures maximum efficiency, protection, and control — all in one compact, intelligent design.

⚙️ Applications

The 18kW Fan Drive is built for medium- to high-power motor control across a wide range of industries, including:
– HVAC & Heat Pump Systems — precise air volume control, improved efficiency
– Industrial Ventilation & Exhaust Systems — reliable operation under long duty cycles
– Water Pumps & Cooling Towers — smooth soft-start, lower energy consumption
– Factory Automation & Environmental Equipment — stable motor performance and protection

💡 Core Technologies

Our VFD integrates advanced digital motor control and industrial-grade protection into a single, compact module.
Built on decades of motion control expertise, it combines power and precision:

• Advanced Sensorless FOC Control:
Accurate torque and speed regulation — even without an encoder.
Stable startup for high-inertia fan loads.
Smooth operation with low acoustic noise and reduced motor heating.

• High Efficiency & Low Loss:
Up to 96–97% conversion efficiency for reduced operational cost.
Optimized carrier frequency (8–16kHz) for noise–efficiency balance.
Two-level inverter topology ensures economic, robust performance at 18kW class.

• Comprehensive Protection:
Overcurrent, Overvoltage, Undervoltage, Overload, Short Circuit, Phase Loss, and Overtemperature protection.
Hardware-level IGBT short-circuit protection (<2µs response).
Thermal derating above 85°C for enhanced lifespan.

• Industrial Connectivity:
Built-in CANopen communication.
Optional Modbus RTU for easy system integration.
Compatible with most industrial control systems.
