TWM325502U - Current sensing device of close loop - Google Patents

Abstract

Thic, a current sensing device which it's ouput signal is got by feeding back the input current and is so called close loop current transducer. It include Printed circuit and electronies components (PCBS), magnetic detective element, magnetie materials (cores), wires and signal output pins. The operation theory is: current flow through primary side wire, which wounded on the magnetic materials, cause magnetic materials yield magnetic field applied on magnetic detective element. The element will generate a small voltage. Through the PCBS, this voltage transfer into current signal then fiow into the secondary side wire which is wounded on the same magnetic materials. The primary side wire, the secondary side wire and the cores are insulated by the well designed plastic case. Since the primary side and the secondary side wire are wounded on the same cores, there would be nearly no Hysteresis loss on the cores. This way the measure accuracy can be improved. This device is a very easily assembly, lower cost and friendly used module.
