Single Phase ModBus Power Meter

General Description

The QI Power 485 is a family of Single Phase Power Meters that can convert Current and Voltage to indicate the Power on a Modbus network. The QI Power 485 measures Current with a built-in Hall effect sensor by inserting the cable through the device. The options are as below.

  • QI Power 485 50A AC/DC 800V AC, 1000Vdc.
  • QI Power 485 300 300A AC/DC 800V AC, 1000Vdc.
  • QI Power 485 LV 50A AC/DC 80V AC, 100Vdc.
  • QI Power 485 300 LV 300A AC/DC 80V AC, 100Vdc.
The QI Power 485 provides the following outputs.
  • Current, Voltage rms.
  • Current, Voltage Peak.
  • Active Power.
  • Reactive Power.
  • Apparent Power.
  • Frequency.
  • Total Harmonic Distortion.
  • Energy kWh Bidirectional.
The unit can be mounted on a DIN rail or screwed terminal. Set up is by either the DIP switches or by the free software available from our website. Isolation is provided up to 3000Volts on the Current input and 4 000 Volts on the Voltage input.
