Description
The analyzer measures active and reactive energy, summing (easy connection mode on) or separating imported
energy from exported energy. It manages two energy tariffs using a digital input or Modbus command. It can be
equipped with an optional output to communicate measurements: pulse output, RS485 Modbus port or M-Bus
port. It measures one DIN module, with backlit LCD display with sensitive touch screen areas for page scrolling and
parameters setting.
