Designed for High Power Industrial Motor Control
This 500 kW VFD inverter is purpose-built for demanding industrial environments where large motors, high torque, and continuous operation are required. By precisely controlling motor speed and torque, the variable frequency drive reduces mechanical stress, minimizes inrush current, and significantly lowers energy consumption compared to traditional direct-on-line (DOL) motor starters.
The 500 kW variable frequency drive enables smooth motor startup, stable operation under fluctuating loads, and optimized process control across a wide range of industrial applications. Whether used as a pump VFD, fan inverter, compressor drive, or conveyor motor controller, this high power inverter improves system efficiency, reduces downtime, and extends equipment lifespan.

Energy Saving & Cost Reduction with 500 kW VFD
One of the key advantages of using a 500 kW VFD is substantial energy savings. In variable torque applications such as pumps and fans, reducing motor speed by just 20% can lower energy consumption by up to 50%. The variable speed drive dynamically adjusts motor output based on real-time load demand, eliminating unnecessary power usage.
For industrial plants, utilities, and infrastructure operators, deploying a high power VFD inverter can result in:
-
Lower electricity bills
-
Reduced peak demand charges
-
Decreased mechanical wear
-
Lower maintenance costs
-
Improved system reliability
This makes the 500 kW variable frequency drive a critical component for energy-efficient industrial automation and power optimization.
Advanced Protection & Reliable Operation
The PowerNex 500 kW industrial VFD integrates comprehensive protection functions to ensure safe and stable operation in harsh environments:
-
Over-voltage & under-voltage protection
-
Over-current & short-circuit protection
-
Motor overload protection
-
Phase loss & phase imbalance protection
-
