is the lesser of 1 µs or the duration of the bunched beam packet resulting from one microwave modulator pulse.

4. In machines based on microwave accelerating cavities, the peak beam current is the average current in the time duration of a bunched beam packet.
3. A. 225. Frequency changers or generators, usable as a variable frequency or fixed frequency motor drive, other than those specified by 0B001.b.13., having all of the following characteristics:
a. Multiphase output providing a power of 40 VA or greater;
3. A. 225. b. Operating at a frequency of 600 Hz or more; and
c. Frequency control better (less) than 0.2%.
Note 1: Item 3A225 only applies to frequency changers intended for specific industrial machinery and/or consumer goods (machine tools, vehicles, etc.) if the frequency changers can meet the characteristics above when removed, and subject to General Note 3.
Note 2: For the purpose of export control, the Government will determine whether or not a particular frequency changer meets the characteristics above, taking into account hardware and software constraints.
Technical Note:
1. Frequency changers in 3A225 are also known as converters or inverters.
2. The characteristics specified by item 3.A.1. may be met by certain equipment marketed such 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).
            N.B.: "Software" specially designed to enhance or release the performance of frequency changers or generators to meet the characteristics above is controlled in 3D202.
            N.B.:  SEE 0B001 FOR FREQUENCY CHANGERS AND GENERATORS SPECIALLY DESIGNED OR PREPARED FOR THE GAS CENTRIFUGE PROCESS.
3. A. 226. High‑power direct current power supplies, other than those specified by 0B001.j.6., having both of the following characteristics:
a. Capable of continuously producing, over a time period of 8 hours, 100 V or greater with current output of 500 A or greater; and
b. Current or voltage stability better than 0.1% over a time period of 8 hours.
3. A. 227. High‑voltage direct current power supplies, other than those specified by 0B001.j.5., having both of the following characteristics:
a. Capable of continuously producing, over a time period of 8 hours, 20 kV or greater with current output of 1 A or greater; and
b. Current or voltage stability better than 0.1% over a time period of 8 hours.
3. A. 228. Switching devices, as follows:
a. Cold‑cathode tubes, whether gas filled or not, operating similarly to a spark gap, having all of the following characteristics:
1. Containing three or more electrodes;
2. Anode peak voltage rating of 2.5 kV or more;
3. Anode peak current rating of 100 A or more; and
4. Anode delay
