Datasheet
Application
Shunts provide an accurate DC millivolt signal to drive ammeter indica-
tors, overload protection and control devices, especially for higher am-
perage. They supply a voltage drop proportional to the DC current which
is measured and indicated by a moving–coil meter with the dial calibrated
in amps.
In accordance with DIN standard 43 703 shunts are available from 1 A up
to 15,000 A with an accuracy of 0.5%. Standard voltage drop is 60 mV or
150 mV. Intermediate current ratings, other voltage outputs, better accu-
racy and purpose–built shunts can be supplied.
Shunts are manufactured in three different format versions depending on
current ratings.
Operating Principle
The current passing through the shunt produces a proportional voltage
drop. A moving coil instrument connected to the shunt measures the
voltage drop across the shunt terminals.
Shunts are calibrated in such a way that they produce an accurately
defined voltage drop (60 mV, 150 mV or other).
