产品规格
* With 200V~5000V programmable impulse voltage, it is capable of low-energy testing, without damaging the coil.
* Provide high-speed sampling rate of 100MHz, which enhances the testing ability for partial discharges.
* 320 x 234 color LCD display clearly for the user to view waveform and test results.
* Provide user-friendly operation interface.
* Low inductance during impulse testing, minimum to 0.2uH.
* Provide 4 kinds of detection modes: AreaSize Comparision, DiffZone Comparision, Corona Amount Comparision, and Corona Number Comparision.
* The comparative result shows Pass/Fail directly, informing operators the detect test result within a short period of time.
* Offer measurement functions for voltages, timing and frequencies, which provide user a carry-out analysis in detail.
* Able to save 360 sets of standard waveform result of the coil for users to download and implement into testing.
* Provide RS-232 to PC connection. Just using standard text command, you can writing control program and data for communication easily.
it's the best way to set up the testinf system for mass production.
* To make analysis easier, 7920L/7920 offers USB2.0 interface to connect with PC for users to upload or download the parameters of waveforms results.
* Provide the control function for external I/O, such as the Handler adopts standard D SUB 9-pin connector for connecting with automatic or semi-auto
