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

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.

Conditions of acceptability
When installed in the end-use equiment, consideration shall be given to the following:
1 - These devices must be mounted in a suitable end-use enclosure.
2 - The terminals have not been evaluated for field wiring.
3 - The LV 25-P series are intended to be mounted on the printed wiring board of the end-use equipment (with a minimum CTI
of 100).
4 - The LV 25-P series shall be used in a pollution degree 2 environment when the Printed Wiring Board has not been coated.
5 - The LV 25-P series shall be mounted on the load side of line filters.
6 - Low voltage circuits are intended to be powered by a circuit derived from an isolating source (such as a transformer,optical
isolator,limiting impedance or electro-mechanical relay) and having no direct connection back to the primary circuit (other
than through the grounding means).
7 - Base on results of temperature tests, int he end use application, a maximum of 100 °C cannot be exceeded at soldering
point between primary coil pin and soldering point of on the primary bus bar (corrected to the appropriate evaludated max.
surrounding air).
Marking
Only those products bearing the UL or UR Mark should be considered to be Listed or Recognized and covered under UL’s
Follow-Up Service.Always look for the Mark on the product.
