Type Selection
CptBSoft: software to program the working parameters of the transducer and to read the energy and the instanta- neous variables. The kit includes the communication cable.
Range codes
AV5: 400/(690)VL-L/5(6)AAC VL-N: 185 V to 460 V VL-L: 320 V to 800 V
AV6: 120/(208)VL-L/5(6)AAC VL-N: 45 V to 145 V
VL-L: 78 V to 250 V Phase current: 0.03A to 6A Neutral current: 0.09 to 6A
System
3 : 1, 2 or 3-phase, unbalanced and balanced load, with or without neutral
