Ultra-stable closed-loop Fluxgate ULTRASTAB current transducers for applications requiring interference-resistant, parts-per-million accuracy from 12.5 to 1000A. Galvanic isolation is reinforced by an electrostatic shield across all models. The ITN 12-P Ultrastab and ITN 12-P/SP2 Ultrastab add a metal housing for enhanced EMC immunity and a PCB-mount configuration for direct integration into measurement instruments — these are the PCB-mount variants in the range; all other models (ITN 600-S, 900-S, 1000-S Ultrastab) are panel-mount. An integrated LED and status signal output confirm normal operating state across all versions.

Applied in calibration laboratories, precision scientific instruments, MRI gradient amplifiers, medical environments, and any measurement system where current uncertainty must be expressed in parts per million and long-term stability under thermal and electrical interference is a requiremen
