The QI-POWER-485 is a Single-phase Power meter able to measure
the TRMS AC/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 congurable by
RS485, DIN rail mounting, 4kV galvanic isolation for Voltage input.
The smallest Energy meter of the market !

REMARKS:
• Modbus connections: A+ and B- as per Modbus RTU
standards;
• Modbus Register reference: with reference to the
logical address, for ex. 40010, corresponds to physical
address n°9 as per Modbus RTU standard;
• Modbus functions supported: 3 (Read multiple
registers, max 100), 6 (Write single), 16 (Write multiple).
• Any changes made by dip-switch required to switch
o the power supply or sending reset command.
Using a serial link RS485-USB you can connect the QI-
POWER-485withtheinterface programFACILEQI-POWER-485.
Using this software, allows you to set the Modbus address,
baudrate, delay, the TV and TA ratio, to modify a lter in
order to have fastest responce time instead of a more stable
measurement (lter range from 1-speed to 5-accuracy) and
to measure frequency on current channel instead of voltage
channel . You can download the FACILE QI-POWER-485 free
of charge from our website www.qeed.it (section Products /
Download Software).
A second way to programming the QI-POWER-485 is by
using the Modbus Register Map directly. Download it from
our website: www.qeed.it (section Products / Dowload
Software/ Facile QI-POWER-485 or section Products /
Network Analyzers ).
MOUNTING: The Power Meter QI-POWER-485 can be
mounted in any position (see photo below), horizontal or
vertical mounting, horizontal or vertical through the two

CAUTION: Magnetic elds of high intensity can vary the values
measured by the transformer. Avoid installation near permanent
magnets, electromagnets or iron masses that induce strong changes in
the magnetic eld. If any irregularity recommend reorient or move the
transformer in the area most appropriate.

If you want to set the device by FACILE QI-POWER-485 set the dips in 0. If you
want to set by RS485 directly, set the rst dip to 1 (up) then use the second dip
for baudrate setting ( 0 for 9600 or 1 for 38400). After the settings, please save
the conguration by the COMMAND register, then switch o the power supply,
before to switch on the power supply set the dips in 0.

FACILE QI-POWER-485
The free interface program FACILE QI-POWER-485 is the fastest way
to congure the device . There is only one conguration screen (see
picture shown ) . The changes made to the program act on the register
of the QI-POWER-485 , if you want to restore the default conguration ,
just press the button FACTORY DEFAULT .
TYPE OF MEASURE : Allows the selection of the measure RMS or DC only
to dene the sign, positive or negative, of reading.
SAVE ON ENERGY FLASH: It is possible to activate the saving of the
counters directly on the device’s ash memory .
REPORT OF TRANSFORMATION : In case you would use the TA and / or
TV , you can dene the transformation ratio for the current input and
voltage input , the default ratio is 1:1.
FILTER: Allows you to insert a lter on reading in order to get
more speed in responding (value 1) or a more stable and accurate
measurement ( value 5 ), by default the value is set to 2. You can choose
between intermediate values already set or manually enter the desired
lter by choosing the CUSTOM option from the menu , in this case, you
can set the following parameters : ltering in DC, ltering in AC (default
value 5 ), Frequency measurament on Current channel.
Energy storage data on ash memory : 4,5 years minimum, 45 years typical.
Minimum Current measurement (cut o): 100mA
Minimum Power measurement (cut o) : 1 W
Measurement refresh : every 50 cycles or 1 second (the faster), programmable by
