ST-248A AC Ratio Transformer
Active
AC Ratio Standard, 1:1 Ratio, Binding Post Termination, Electrostatic Shields (not CE certified)
Advanced Energy's TEGAM ST-248A transformers are designed to meet the requirements of a wide variety of bridge circuitry, isolation and calibration applications. The ST-248A can be used to provide a balanced output from an unbalanced source. These transformers may be combined with TEGAM ratio transformers in bridging circuits, to isolate the null indicator. The ST-248A features very accurate 1:1 ratio for isolation or phase inverting applications. These units are also used with TEGAM decade ratio transformers to provide 180 degree phase shift to the input or output of the instrument in certain bridge applications. The ST-248A also has electrostatic shields and a center tapped secondary.
