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.
