Frequency changers or generators, other than those specified in 0B001.b.13., usable as a variable or fixed frequency motor drive, having all of the following characteristics: N.B. 1: “Software” specially designed to enhance or release the performance of a frequency changer or generator to meet the characteristics of 3A225 is specified in 3D225. N.B. 2: “Technology” in the form of codes or keys to enhance or release the performance of a frequency changer or generator to meet the characteristics of 3A225 is specified in 3E225. a. Multiphase output providing a power of 40 VA or greater; b. Operating at a frequency of 600 Hz or more; and c. Frequency control better (less) than 0,2 %. Note: 3A225 does not control frequency changers or generators if they have hardware, “software” or “technology” constraints that limit the performance to less than that specified above, provided they meet any of the following: 1. They need to be returned to the original manufacturer to make the enhancements or release the constraints; 2. They require “software” as specified in 3D225 to enhance or release the performance to meet the characteristics of 3A225; or 3. They require “technology” in the form of keys or codes as specified in 3E225 to enhance or release the performance to meet the characteristics of 3A225. Technical Notes: 1. Frequency changers in 3A225 are also known as converters or inverters. 2. Frequency changers in 3A225 may be marketed as Generators, Electronic Test Equipment, AC Power Supplies, Variable Speed Motors Drives, Variable Speed Drives (VSDs), Variable Frequency Drives (VFDs), Adjustable Frequency Drives (AFDs), or Adjustable Speed Drives (ASDs).

Frequency changers capable of operating in the frequency range of 300-600 Hz

Frequency Changers (also known as converters or inverters) Frequency changers, other than those specified in entries 0B001.b.13 or 3A225 of Annex 1, having all of the following characteristics, and specially designed software therefore: i. Multiphase frequency output; ii. Capable of providing a power of 40 W or greater; and iii. Capable of operating anywhere (at any one point or more) within the frequency range of between 600 and 2 000 Hz. Technical Notes: (1) Frequency changers are also known as converters or inverters. (2) The functionality specified above may be met by certain equipment described or marketed as electronic test equipment, AC power supplies, variable speed motor drives, or variable frequency drives.

Frequency changers or generators, and Variable Speed electrical drives, other than those prohibited by 0B001 or 3A225, having all of the following characteristics, and specially designed components and software therefor: a. Multiphase output capable of providing a power of 10 W or greater; b. Capable of operating at a frequency of 600 Hz or more; and c. Frequency control better (less) than 0,2 %. Technical Note: Frequency changers are also known as converters or inverters. Notes: 1. Item II.A3.004 does not control frequency changers that include communication protocols or interfaces designed for specific industrial machinery (such as machine tools, spinning machines, printed circuit board machines) so that the frequency changers cannot be used for other purposes while meeting the performance characteristics above. 2. Item II.A3.004 does not control frequency changers specially designed for vehicles and which operate with a control sequence that is mutually communicated between the frequency changer and the vehicle control unit.
