1.3 Current Transformer Current ratio
The unit can be configured to operate with CT ratio between primary and secondary current is 1 and 2000.
There are two options of secondary current input: 1A or 5A
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.

2. Start-up Screens
The first screen lights all display segments and can be used as a
display check
The second screen indicates the firmware installed in the unit
and its build number.
Next the unit performs a self-test and indicates if the test passes.
3. Measurements
The buttons operate as follows
Selects the Voltage and Current display screens
In Set-up Mode, this is the “Left” or “Back” button.
1.4 RS485 Serial –Modbus RTU
This uses an RS485 serial port with Modbus RTU protocol to provide a means of remotely monitoring and
controlling the 2RAE96L4C485E series.
Set-up screens are provided for setting up the RS485 port.
1.5 Pulse output
This provides 2 pulse outputs those clocks up measured active and reactive energy. The constant for both
output are configurable.
