The
QI-POWER-485-300-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, 4 kV galvanic isolation for Voltage input.
Suitable for measurements with
varying frequencies
(Wind, Hydro, Shipbuilding Industries, Aviation).
DC Motor Control, Telecom applications, Data
Centers, UPS, Batteries monitor.
