Single Phase Power Datalogger

General Description

The QA Power M is a Power meter with a built-in datalogger and Modbus RTU port that can log AC/DC Power, Current, Voltage, Frequency and kWh. It can accept Voltage up to 600V AC and 1000V DC and Current up to 10A direct or higher, with the use of current transformers. The QA Power M has both analog and digital outputs. The analog output can be either 4-20mA, 0-10V or 0-20mA. The digital is programmable to be either a pulse or an alarm output.
The QA Power M is programmable via the USB port or the RS485 port with the aid of the free software. The DIP switch is only usable for the Modbus address and Baud rate settings. The Datalogger information is stored on the USB flash drive.
The QA Power M logs the following to the USB Flash drive.

  • Voltage rms, Instantaneous Peak, Average, and Max.
  • Current rms, Instantaneous Peak, Average, and Max.
  • Power Active, Reactive, Apparent.
  • Frequency, Min, Max.
  • Total Harmonic Distortion.
  • Energy, Total, Positive, Negative.
  • Total Harmonic Distortion.
The unit is DIN Rail mounted. 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.
