Details

The QI-Power-485 is a single phase power meter used to monitor the RMS AC of DC current and voltage levels in a network. The range consists of 4 different models that cover different voltage and current ranges. Units are available for low currents of up to 50A and higher current levels of up to 300A, plus voltage ranges of up to 100V and up to 1,000V. All 4 units provide an RS485 Modbus RTU output including the following parameters: IRMS, VRMS, Watt, Var, Va, Ipk, Frequency, Cosφ, Energy bidirectional and THD. Units are fully configurable via RS485 or the Facile QI-POWER-485 software via a RS485 to USB converter.

Facile QI-POWER-485 Interface SoftwareFacile QI-POWER-485 Software

The free interface program Facile QI-POWER-485 is the fastest way to configure the device. The software has only one configuration screen, shown on the right, which allows all the parameters to be configured. The changes made to the program act on the Modbus registers of the QI-POWER-485. In the event you need to restore the default configuration, just press the button FACTORY DEFAULT and the original settings will be restored.

Using a serial link RS485-USB (eg. USB-i485 RS485 to USB Converter) you can connect the QI-POWER-485 with the interface program FACILE QI-POWER-485. The 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. The software is available to download free of charge.

A second way to programming the QI-POWER-485 is by using the Modbus Register Map directly. The register map is available on request.
