ANSI/AHRI 1210 (I-P)-2011: Performance Rating of Variable Frequency Drives

Standard Scope:
This standard applies, within the heating, ventilating, air-conditioning and refrigeration (HVACR) context, to 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.
