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

Air-Conditioning, Heating and Refrigeration Institute (AHRI). Approved by ANSI on Apri 16, 2012. 2011. 18p. The purpose of this standard is to establish for Variable Frequency Drives (VFDs): definitions; classifications; general test requirements; rating requirements; minimum data requirements for Published Ratings; marking and nameplate data; and conformance conditions.
This standard is intended for the guidance of the industry, including manufacturers, engineers, installers, contractors and users.
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
