1. APPLICATION The P43 transducer is a programmable digital instrument destined for the measurement and parameter conversion of 3 or 4-wire three-phase power networks, in balanced and unbalanced systems. It ensures the measurement and conversion of measured values into standard analog current signals. Two relay outputs signal the overflow of selected quantities, and the pulse output can be used for the con- sumption monitoring of the 3-phase active energy.
Transducer output signals are galvanically isolated from the input signal and the supply. Outside the transducer, there are socket-plug 2. TRANSDUCER SET The set of the P43 transducer is composed of: - P43 transducer 1 pc - user’s manual...
