Voltage Transducer LV 100-2500
VPN = 2500 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).

Mechanical characteristics
Remarks
· General tolerance
· Fastening
· Connection of primary
· Connection of secondary
· Connection to the ground
· Fastening torque
± 0.3 mm
· 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.
