Kele AC Current Transducer

 

Models 4CTV and 4CMA AC current transducers are AC amperage-to-analog DC transducers. Either current transducer can be used to directly monitor loads of up to 20A. For loads of 20-5000A, an external current transformer can be used. Developed for energy management and building automation systems, BAS, the Model 4CTV transducer converts an AC current to a 0-5 volt DC current. The Model 4CMA transducer converts an AC current to a 4-20 mA current that can be monitored by any processor that accepts analog DC voltage or current.
