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. API series 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.
