• Adjustable Demand time • Summer-Winter time application Applications MPR-3 series analyzers are 3 phase network analyzers. They are microprocessor-based devices designed to measure all parameters of an electrical network, calculate consumption and display them on the LCD screen. Thanks to the RTC clock chip and flash memory on the device, the operations performed by the operator such as interruption records, time and setting changes, reset operations are recorded in real time.
