Clamping Current Sensor - Single Phase

The Clamping Current Sensor is a solid state transducer for measuring the current in fans, pumps and other HVAC equipment. The new clamping / split core current transformer allows installation without interrupting the high voltage wiring. It features AC input, range 10A, 20A, 50A jumper selectable, 0-5VDC out. The signal is proportional to the average current and vary slightly from the results shown on an RMS measuring ammeter, depending on the load.
