List of Items Controlled
Related Controls: (1) See ECCN 3D201 for “software” “specially designed” for the “use” of equipment described in this entry. (2) See ECCN 3D202 for “software” “specially designed” to enhance or release the performance characteristics of frequency changers or generators to meet or exceed the level of the performance characteristics described in this entry. (3) See ECCNs 3E001 (“development” and “production”) and 3E201 (“use”) for “technology” for items controlled under this entry. (4) Frequency changers (a.k.a. converters or inverters) “specially designed” or prepared for use in separating uranium isotopes are subject to the export licensing authority of the Nuclear Regulatory Commission (see 10 CFR part 110).
Related Definitions: N/A
Items: 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%.
Notes:
1. This ECCN controls frequency changers intended for use in specific industrial machinery and/or consumer goods (machine tools, vehicles, etc.) only if the frequency changers can meet the performance characteristics described in this entry when removed from the machinery and/or goods. This Note does not exclude from control under this entry any frequency changer described herein that is the principal element of a non-controlled item and can feasibly be removed or used for other purposes.
2. To determine whether a particular frequency changer meets or exceeds the performance characteristics described in this entry, both hardware and “software” performance constraints must be considered.
Technical Notes:
1. Frequency changers controlled by this ECCN are also known as converters or inverters.
2. The performance characteristics described in this ECCN also may be met by certain equipment marketed as:
- Generators,
- electronic test equipment,
- AC power supplies,
- variable speed motor drives,
- variable speed drives (VSDs),
- variable frequency drives (VFDs),
- adjustable frequency drives (AFDs),
- or adjustable speed drives (ASDs).
