Our AC current and voltage sensors with AC output are designed for those who prefer to condition their own signals after sensing.
Our high linearity current sensors with AC voltage output will monitor from 2 to 600 amps, but this range can drop to as low as 100 mA with additional windings through the sensor hole. These sensors are current to voltage converters, and the output is calibrated to provide 3.5 Vrms at full scale (customer specified current) in the 6 Hz to 14 MHz frequency range. The flux surrounding the wire being monitored supplies power to the sensor, but requires much less power than a CT. The magnetic air-gap prevents saturation at high current and exhibits a monotonic transition into the overload region. The air-gap also eliminates dangerous conditions associated with open secondary windings of CT's. These sensors come packaged in our "A" thru "E" case sizes. Case size will depend on wire diameter and the amount of current being monitored. You may also specify what type of output terminals you would like installed (lug nuts, solder terminals, wire, etc).
Our standard AC voltage sensor with AC voltage output will monitor from 30 to 1000 Vrms. The voltage sensor uses a transformer which has been optimized with external circuitry for sensing of potential while drawing a minimum of power. Typically these units will draw less than 2 mA from the voltage being monitored. The transformer is also air-gapped so that large voltage excursions as well as transient phenomena are accommodated. The output of the sensor is calibrated to provide 3.5 Vrms at full scale (customer specified voltage) and isolated from the line. The low dissipation effects and high frequency response make these units ideal for monitoring everything from voltage harmonics created by nonlinear loads, to voltage changes caused by lightning strikes. The unit comes packaged in our standard "D" size case.
