The QE Power M is a universal multipurpose low cost, single phase Voltage, Current, and Power to RS485 Modbus RTU converter. The QE Power M can measure up to 300 Volts, or with the use of voltage transformers, a higher Voltage can be connected to the QE Power M. The current must be connected via Current Transformers as the current input is not isolated. The Single Phase Power to RS485 can accept 1 or 5 Amp Current transformer inputs, 333mV and Rogowski probes.
The QE-Power-M is powered by AC or DC power supplies and has isolation between the Power Supply, Voltage input, and the Modbus RTU RS485 output. The QE Power M can be used as an AC Voltage to Modbus RTU converter.
The QE-Power-M can measure and calulate the following:
The QE-Power-M Plus can also measure and calulate the following:
