AC Current Transducers
Description
The Models 278/2780 AC Current Transducer is designed to accept an AC current input, and provide a proportional DC output. A linear transformer input is coupled to a solid-state output amplifier. The Models are powered by a 115 VAC source, and is socket-mounted for ease of use.
Models 278/2780 Current Transducers can be used with computer and programmable controls to provide: motor and power control; supervisory data acquisition; load monitoring; feedback control; energy management.
