QI-POWER-485-LV
The QI-POWER-485-LV is the LOW VOLTAGE
version of the Single-phase Power meter QI-
POWER-485, able to measure the RMS AC or DC
Current and Voltage. On the RS485 Modbus are
available: Irms, Vrms, Watt, VAR, VA, Vpk, Ipk,
Frequency, Cosφ, Energy bidirectional and THD.
The device is fully configurable by RS485, DIN rail
mounting, 4kV galvanic isolation for Voltage input.
The images/schemes proposed are to be considered indicative and not binding
