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

Standard Scope

This standard establishes definitions, classifications, test requirements, rating requirements, minimum data requirements for published ratings, marking and nameplate data, and conformance conditions for variable frequency drives (VFDs).

AHRI Standard 1210 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.


This standard does not apply to VFDs applied to motors other than those listed in Section 2.1.
