Application: The STWA1AH makes it possible to
monitor the value of an AC current. The output signal
can be evaluated or displayed with components with
analog inputs, e.g. ZIEHL TR210, STW1000/V2 or
MINIPAN

The STWA1AH is a measuring
transducer for AC currents 0...15
A. Multiple loops of the conductor
through the transformer reduces
the measuring range corres-
pondingly (for instance to 0...5 A
with three loops).
For the monitoring of currents
of any level, the STWA1AH is
simply looped into the secondary
circuit of a large transformer with
secondary 5 A (cable three times
through the STWA1AH). Conse-
quently, the output is proportional
to the primary current of the
transformer, e.g. 0...100 A for a
transformer with 100/5 A.
The analog output is isolated. The
load should be 50...300 Ω.
