THREE-PHASE NETWORK ANALYSER 90A
Read all the instructions carefully
The ADR-D 400 D90 network analyzer is a direct connection digital multimeter for
three-phase systems up to 90 A for true effective value measurements (TRMS). The
isolated RS-485 serial output allows, through the MODBUS protocol functions and
the use of the relative registers, to connect the analyzer to a Master device (PC/
PLC...) for data visualization and archiving.
