QI-POWER-485-LV

POWER /ENERGY METER SINGLE PHASE AC/DC TRMS - RS485 MODBUS

Description

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.

Using a serial link RS485-USB you can connect the QI-POWER-485-LV with the interface program FACILE QI-POWER-485. Using this software, allows you to set the Modbus address, baudrate, delay, the TV and TA ratio, to modify a filter in order to have fastest responce time instead of a more stable measurement (filter 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-LV 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-LV can be mounted in any position (see photo below), horizontal or vertical mounting, horizontal or vertical through the two.

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 first 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 configuration by the COMMAND register, then switch off 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 configure the device. There is only one configuration screen (see picture shown). The changes made to the program act on the register of the QI-POWER-485-300, if you want to restore the default configuration, just press the button FACTORY DEFAULT.

TYPE OF MEASURE:
allows the selection of the measure RMS or DC only to define 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 flash memory .

REPORT OF TRANSFORMATION:
in case you would use the CT and / or VT, you can define the transformation ratio for the current input and voltage input, the default ratio is 1:1.
 

FILTER:
allows you to insert a filter 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 filter by choosing the CUSTOM option from the menu, in this case, you can set the following parameters: filtering in DC, filtering in AC (default value 5), Frequency measurament on Current channel.


MIN CURRENT THRESHOLD
(mA): Allow you to set the minimum current value (Cut off). Under this value the device measure Zero.


MIN POWER THRESHOLD (W):
Allow you to set the minimum power value (Cut off). Under this value the device measure Zero.
