When a single turn is inserted through the window area of the transformers, the resulting turns ratio of 2000:1 allows the output to be calculated based on the input current. With an input current ranging from 0-20 Amps, output voltage tolerances vary slightly based on the loading resistor, but typically fall in the 3% to 8% range.
Constructed with commonly used laminations and a 3-flange bobbin, these units have an open section within the window area to allow up to a 0.160 inches diameter insulated conductor. Typical dimensions are 1.00 inches length × 0.920 inches width × 8.825 inches height. HIPOT rating from secondary winding core is 1,500 Vac.
