Current Transformer, 91.4 Centimeter CableD6 Labs Current Transformer DrawingGeneral DescriptionThis external current transformer is designed to work with a Whisker.Block® that is configured with a 25 amp current Transformer (C2) input with 0-5 VDC digital output. When properly mounted, this sensor will detect current from 0 to 25 amps A.C.PowerThis is a passive sensor that requires no external power. MountingThis current transformer is connected to the D6 CBL-M8MALE26AWG wire harness as shown in the wiring diagram. This sensor is housed in a padlock type assembly that is clamped around the AC power line that is to be monitored.Compatible Whisker.Blocks®Part NumberWB1-9-xx-C2NNNNNN-0000-xxWB1-9-xx-C2C2C2NN-0000-xxWB1-9-xx-C2TRTRNN-0000-xxWiringD6 Labs Sensor Probe AssemblyRecommended Wiring:ConnectorPinSensor WireDescription12Blue0-5 VDC Analog Input14WhiteGround ReferenceElectrical SpecificationsParameterMinimumTypicalMaximumUnitsRated Input Current (Continuous)25Amps ACMax Input(1 Min)37.5Amps ACRated Output5VDCOutput Ripple Voltge5% output voltage%Accuracy±2%%Output Impedance7kΩIsolation Impedance (500VDC)100MΩWorking Voltage660VoltsWorking Temp-2560Degrees FahrenheitStorage Temp-3090Degrees FahrenheitFrequency Range5060HzDielectric Strength (50Hz, 1Min)3.5KV
