Current and voltage transducers are applied for the measurement of sinusoidal alternating currents (Nominal-input current from 0,05 to 20A) and alternating voltages (Nominal input voltages from 200 to 690 V). For higher currents or voltages transformers have to be connected before. All transducers are able to snap on DIN rails. Celsa; CfWIdNV!

TRANSDUCERS FOR POWER Transducers for active and reactive power • Class 0,5 • For mounting on DIN rail (DIN EN 50 022) or for screw fixing with 2 cylinder-head screw M4 Description This transducer is applied for measuring active and reactive power of sinusoidal current at a frequency of 50-60Hz. They can be directly connected to rated input currents of 0,1 to 20A and to rated input voltages of 50 to 720 V. At higher currents and/or voltages they must be preceeded by AC measurement transformers. An auxiliary voltage supply always is required. If the measurement circuit voltage does not vary...
