AT and ATR Series Current Transducers combine a high capacity current transformer
AT and ATR Series Current Transducers combine a high capacity current transformer and signal conditioner into a single package for average responding or True RMS (ATR) current load applications. Multiple or jumper selectable input ranges and a choice of industry standard 4-20mA, 0-5VDC or 0-10VDC outputs make the AT/ATR Series an ideal choice for use in automation systems, datalogging appli- cations or with panel meters. Available in split core or solid core configurations.
