Impulse tester 7720
The MICROTEST 7720 is an Impulse Winding Tester offering pulse voltage outputs from 100V to 5000V. Featuring eight testing channels, it uses damping attenuation waveforms generated by L/C resonance to examine magnetic components for defects, including short circuits between coils or winding wire layers. The tester provides several comparison modes, such as total area, area difference, corona count, jitter count, and waveform comparison, ensuring precise detection and identification of faulty products.
Features:
- Lowest Inductance (50uH)
- 8 Channels
- High voltage calibration
- programmable impulse voltage
- Built-in storage 200 sets testing waveform
- Total area comparison
- Differential area comparison
- Wave comparison
- Flat and Corona
- Support RS-232, remote and printer interfaces
- Key lock function to prevent operators from accidentally touching the keys
