Product Description

*5/5A current transformers are used for measuring energy consumption on the power grid. A current transformer is similar to any other transformer. It has a primary winding, a magnetic core, and a secondary winding. The primary winding will usually be a single turn and the secondary winding will be *0s or **0s of turns. Then by coupling the primary and secondary windings the amperage on the secondary winding will be proportional to the primary winding.

ATO current transformer looks almost identical to a current transformer. We see these used more in industries where we are monitoring motor or heater loads for example. It has built in circuitry to generate a low level DC signal base on the AC amps. This will usually be an analog **5VDC, ***0VDC, or ***0mA signal and will occasionally be a pulsed output where the frequency of the pulse is proportional to the amps going through the transducer.
