AHRI 1210 (I-P) and 1211 (SI): Performance Rating of Variable Frequency Drives

This standard applies, within the heating, ventilating, air-conditioning and refrigeration (HVACR) context, to 60 Hz VFDs used in the control of asynchronous induction motors. The range includes all those found within a building including low voltage (≤ 600 V) and drives that are stand alone, not mechanically integrated into motors.
