IT SERIES KWIK-LATCH® CURRENT TRANSFORMERS   The IT KWIK-LATCH® series are wideband current transformers that are used to inductively couple current on cables or conductors to be tested. The latch type design allow fast and simple attachment without having to pass cables or conductors through the aperture. Other aperture sizes and output connectors are available to meet the unique application.   Pertinent Equations   Insertion Loss = db = 20 Log10 Iinduced or I induced = I drive x 10-db I drive 20 Specifications       MODEL       IT-050-1 IT-075-1 IT-125-1 IT-125-2 Electrical         Frequency Range 100KHz -100MHz 100KHz -100MHz 100KHz -100MHz 50KHz - 700MHz Insertion Loss 1 (db) 20 + 3 20 + 3 20 + 3 10 + 3 Turns Ratio 10 10 10 1 Typical Saturation Level         Pulse (amp =m sec) ~20* n .
