Re: frequency range of AC clamp current meters
Marshal,
The clamp type meters I have used in the past have a max frequency of about 400Hz. That is OK for the 150 Hz switching frequency of the Victor. The Jaguar is 15 kHz and although it may show some current on the meter, it will not be accurate and will show considerably less than actual. The type of current transformer Eric linked to also has a frequency response characteristic that will play into the readings. The sheet does not spec the response but I am guessing it is optimized for 60 Hz.
