The multifunction panel meter 2RAE96L4C485E series is a top new-generation intelligent panel meter,
used not only in the electricity transmission and power distribution system but also in the power
consumption measurement and analysis in high voltage intelligent power grid.
This document provides operating, maintenance and installation instructions for the 2RAE96L4C485E
series. The unit measures and displays the characteristics of single phase two wires, three phase three
wires and three phase four wires supplies, including voltage, frequency, current, power and active and
reactive energy, imported or exported, Harmonic, Power factor, Max. Demand etc. Energy is measured in
terms of kWh, kVArh. Maximum demand current can be measured over preset periods of up to
60minutes. In order to measure energy, the unit requires voltage and current inputs in addition to the
supply required to power the product. The requisite current input(s) are obtained via current transformers
The 2RAE96L4C485E can be configured to work with a wide range of CTs, giving the unit a wide range
of operation. Built-in interfaces provide pulse and RS485 Modbus RTU outputs. Configuration is
password protected.
