Schneider Electric (Square D) ATV212HD15N4 20HP Variable Frequency Drive 460V/3PH

The Schneider Electric Square D ATV212HD15N4 is a 20-horsepower, 460-volt, 3-phase variable frequency drive VFD that controls the speed and torque of AC induction motors typically used in HVAC equipment. By changing the electrical output's frequency, it serves as a bridge between the motor and the fixed-frequency power source, enabling precise control over motor speed. This makes it possible for numerous HVAC applications, such as fans, compressors, and pumps, to operate and perform optimally. Motors may run at their most efficient when they have precise speed control, which lowers energy usage and utility expenses. By regulating fan speed in ventilation systems, occupant comfort can be improved by maintaining constant airflow and temperature throughout the facility.
