INVT GD28 Series Flexible General-Purpose VFD
An INVT Variable Speed Drive (VSD) is a high-performance electronic drive designed to control the speed, torque, and direction of AC motors by adjusting the frequency and voltage of the power supplied to the motor. INVT VSDs are engineered for flexibility and reliability across industrial automation, HVAC systems, pumps, fans, compressors, conveyors, machine tools, and other variable-torque or constant-torque applications.
INVT VSDs help improve process control, reduce energy consumption, extend motor life, and optimize system performance in small- to large-scale industrial environments.
