Variable Frequency Drives are the most effective means to reduce energy cost for operating electric motors and provide the highest level of control. IER offers enclosed VFDs in the same packaging as other motor control options to minimize and reduce installation time. Our enclosed system is configurable for a broad range of stand-alone applications ranging from simple pumps and fans to sophisticated machines requiring closed loop speed and position control as well as integrated safety. This rugged system is based on industry leading modular components that allow it to be configured to best meet the demands of the application, the environment and the power supply system.
