Variable Frequency Drives for Industrial Motor Control

Variable frequency drives for pumps, fans, conveyors, compressors, HVAC equipment, machinery, and industrial motor-control applications.

Motor Speed & Process Control

Control motor speed and improve equipment operation

Variable frequency drives control the speed and torque of AC motors by adjusting the electrical frequency and voltage supplied to the motor. This allows equipment to operate at the speed required by the application.

Southern Electronics supplies variable frequency drives for machinery, facility upgrades, control-panel projects, maintenance, replacements, and industrial automation systems.
