MultiTek Special AC Current Transducer
| SELECTION GUIDE M100-AX1 1 ph. aux. powered ave. sensing RMS calibrated M100-AX3 3 ph. aux powered ave. sensing RMS calibrated M100-AAS 3 ph. summation self powered M100-ALS 3 ph. summation auxiliary powered TYPICAL APPLICATIONS The M100-AX1 and AX3 are essentially the same as the M100-AA1 and AA3, but they have auxiliaries which allows the working range to be 0-125% rather than 10-125%. Used where the average sensing of current is required from 0-125% of the nominal current. The M100-AAS and M100-ALS are A.C. Current summation transducers. Both can have up to 3 inputs of either 1, 5 or 10 amps. These inputs are summed by the transducer and one D.C. Output is provided, which is proportional to the sum of the inputs. The M100-AAS is self powered with a range of 10-125% , the M100-ALS is auxiliary powered and provides a 4-20mA output with a working range of 0-125%. Typical application is to measure the total current in a 3 phase system and display it via one meter. For example, if a 3 phase system has 3 current transformers 2500/5 then a moving coil meter could be connected to a M100-AAS scaled 0-7500. Note the C.T.s must all have the same ratio or the output from the transducer will not be the sum of the total current in the system. ORDERING INFORMATION Product Code Input In Output Aux Freq.
