Special AC Current Transducers
DescriptionDIN rail mounting transducers available in 55mm x 112mm or 100 x 112mm DIN rail casesApplicationUsed to conver various inputs into standard DC signals for driving panel meters and for use in control devices.Selection GuideM100-AX11ph. aux. powered ave. sensing RMS calibratedM100-AX33ph. aux powered ave. sensing RMS calibratedM100-AAS3ph. summation self powered.M100-ALS3ph. summation auxiliary poweredTypical ApplicationsThe 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 between 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 amp.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.Technical SpecificationsINPUTRated Value In:1 or 5 Amp C.T. connected 0.5-10 Amp directconnectedPower Consumption:< 0.2VA (AX1, AX3, ALS) < 1VA (AAS)Working Range:0-125% In (AX1, AX3, ALS) 10-125% In (AAS)Rated Frequency:50 / 60 / 400HzFrequency influence:0.005% / HzOverload continuous:4 x InOverload for 1 sec.50 x InOUTPUTRated value mA:0-1 / 5 / 10 / 29mA (AX1, AX3, AAS)Rated value mA:4-20mA (ALS)Rated value volts:Not available on (AAS)Rated value volts:1-5V (ALS)Rated value volts:0-5 / 10V (AX1, AX3)ADJUSTMENTZero:No adjustmentZero:± 2% (ALS)Span± 10% (AX1, AX3, ALS)AUXILIARYA.C.
