Voltage Transducer LV 25-600
VPN =
600 V
For the electronic measurement of voltages : DC, AC, pulsed...,
with a galvanic isolation between the primary circuit (high voltage)
and the secondary circuit (electronic circuit).

•IS is positive when VP is applied on terminal +HT.
•The primary circuit of the transducer must be linked to the
connections where the voltage has to be measured.
•This is a standard model. For different versions (supply
voltages, turns ratios, unidirectional measurements...),
please contact us.
LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
