Current Sensors/Transformers
API Technologies offers a wide range of current sensors that measure electrical current (AC&DC)ꢀand can transform
current from high to low measurable values. APIꢀseries 5300 current sensors are available with current ranges from
3.5 Amps to 800 Amps in six subcategories of current transformers. You will find current transformers in advanced
fault tolerant computers and workstations, control panels reading current flowing to electric transformer, telecom
and communications.
