basic information
【Features】 ○ Ideal for high-frequency durability testing of high-voltage power semiconductors. ○ Developed and adopted a capacitance tuning mechanism. ○ Applies high-precision sine waves (10kHz to 100kHz) at high output (7.5kVrms, 1A). ○ Detects partial discharge, corona discharge, and spark discharge with a uniquely developed high-sensitivity sensor. ○ Can detect partial discharge and corona discharge and stop within 30mSec, allowing for non-destructive testing. ○ Monitors the test state during application and can hold during abnormal stops. ● For more details, please contact us or download the catalog.

Company information
Our Adfox XT series can be tested at frequencies and voltages close to the actual operating circuits of the products. The latest XT-330 can apply a continuous sine wave of 10kVrms at 100kHz, and it can be used for non-destructive testing that instantly stops when corona discharge (partial discharge) is detected, as well as durability testing that takes advantage of high output. Additionally, measurement results can be aggregated on a PC. Adfox Co., Ltd. is a Japanese manufacturer located in Ome City, Tokyo, and our products range from corona testers, sound collectors (hearing aids), to binaural microphones. We also offer OEM products, so please feel free to consult with us.
