Remarks
I
S
is positive when V
P
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.
Secondary terminals
Terminal + : supply voltage + 15 V
Terminal M : measure
Terminal - : supply voltage - 15 V
Terminal
: ground or earth
Connection
LEM reserves the right to carry out modifications on its transducers, in order to improve them, without previous notice.
