The QA-POWER-M is a single phase network power analyser with TRMS (true RMS) function. It is USB configurable, with 4-way galvanic isolation The input range is 1000 vDC / 600VAC, 10A AC/DC. The unit features universal power supply AC/DC, programmable alarm contact, RS485 Modbus output, and a 4-20mA / 0-10vDC output.

The QA-POWER-M also has a data logging function and can record input values and save the data to a USB pen drive memory stick. The logging interval can be set from 1 second to 18 hours. Stored data can be downloaded from the memory stick using the free Windows software supplied and exported to MS Excel, etc. The logger has a Real Time Clock.
