交流電流轉(zhuǎn)換器RA, RAN的產(chǎn)品介紹人：
RA-1 system Single phase, average sensing
RA-3 system Three phase, average sensing
RA-1T system Single phase, True rms sensing
RA-3T system Three phase, True rms sensing
These current transducers are available as average sensing devices calibrated in rms or as true rms units, either with a DC output proportional to the input.
This output signal enables several receivers to be operated simultaneously - such as indicators, recorders, alarm units etc. The input current can be connected via a C.T. or directly.
特性
? High accuracy ±0.2% R.O.
? Precision measurement even for distorted waves
? High immunity to external noise
? Wide selection of input and output range
? Quick and easy mounting
