DETAILED DESCRIPTION

WM20-96

Α modular power analyzer for single, two and three-phase systems.
It is made up of a maximum of three components: the main unit that displays measurements on the LCD display and manages two alarms, and two accessory modules, one with digital outputs and the other for communication.
The digital output module associates alarms with static or relay outputs and/or transmits pulses proportional to energy consumption.
The communication module allows you configure the analyzer and transmit data using a different communication protocol according to the version.
