Introduction
The multifunction panel meter SMART X835 Series are 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.

Eastron SMARTX835 series measure and display the characteristics of single phase two wires and three phase four wires supplies, including voltage, frequency, current, power and active and reactive energy, imported or exported. 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 (CT).

The SMART X835 series 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. 

Unit Characteristics
The SMART X835 can measure and display:
Line voltage and THD% (total harmonic distortion) of all phases
Line Frequency
Currents, Current demands and current THD% of all phases
Power, maximum power demand and power factor
Active energy imported and exported
Reactive energy imported and exported

The unit has password-protected set-up screens for:
Changing password
Supply system selection 1phase2wire, 3phase 4wires
CT Ratio and secondary current
PT Ratio and secondary voltage
Demand Interval time
Reset for demand measurements
Pulse output duration 

A pulse output indicates real-time energy measurement. An RS485 output allows remote monitoring from another display or a computer.

RS485 Serial – Modbus RTU
This uses an RS485 serial port with Modbus RTU protocol to provide a means of remotely monitoring
and controlling the SMARTconnect X835.
Set-up screens are provided for setting up the RS485 port. 

Pulse output

This provides 2 pulse outputs those clocks up measured active and reactive energy. The constant for reactive energy is 5000imp/kVarh. The pulse width for active energy can be set from the Set-up menu.
