Remarks
· General tolerance
· Fastening
· Connection of primary
· Connection of secondary
± 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.
