Application Notes
The range of any Data Stream Transducer can be extended with the use of CR Magnetics’ ANSI
grade current transformers and voltage transformers. In these applications, current transformers
step down higher currents into standard 5 Amp AC current inputs, and voltage transformers step
down higher voltages into standard 120 VAC inputs. This allows the designer to measure any
application with a single transducer.
