Note: 1) R1 = 25 kΩ (L/R constant, produced by the resistance and inductance of
of the primary circuit).
Features
Closed loop (compensated)
voltage transducer using the Hall
effect

min).
Principle of use
For voltage measurements,
a current proportional to the
measured voltage must be
passed through an external
resistor R1 which is selected by
the user and installed in series
with the primary circuit of the
transducer.
Advantages
Excellent accuracy
Very good linearity
Low temperature drift
Optimized response time
Wide frequency bandwidth
High immunity to external
interference.
Applications
Single or three phase inverters
Propulsion and braking choppers
Propulsion converters
Auxiliary converters
Battery chargers.
Application Domain
Traction.

Safety
This transducer must be used in electric/electronic equipment with respect
to applicable standards and safety requirements in accordance with the
manufacturer’s operating instructions.
Caution, risk of electrical shock
When operating the transducer, certain parts of the module can carry hazardous
voltage (eg. primary busbar, power supply).
Ignoring this warning can lead to injury and/or cause serious damage.
This transducer is a build-in device, whose conducting parts must be inaccessible
after installation.
A protective housing or additional shield could be used.
Main supply must be able to be disconnected.
