The
QI-POWER-485-300
is a Single-phase Power
meter able to measure the TRMS AC/DC
current and
voltage
. Internal Calibration certificate for each device
available on request. Configuration software FACILE
QI-POWER-485 for free. The device is fully configurable
by RS485, DIN rail mounting.
Suitable for measurements with
varying frequencies
(Wind, Hydro, Shipbuilding Industries, Aviation).
Telecom applications, Refrigeration, Motors, OEM’s
application.
Suitable for direct measurements
between inverter
and motor.
