Application
SMARTconnect X835 is an economic solution three phase intelligent power analyzer. It used not only in the
electricity transmission and power distribution system, but also in the power consumption measurement and
analysis in low and medium voltage intelligent power grid.
This document provides operating, maintenance and installation instructions for SMARTconenct X835. The unit
measures and displays the characteristics of single phase two wire, three phase three wire and three phase four
wire supplies, including voltage, frequency, current, power, active and reactive energy, imported and exported
energy. Energy is measured in terms of kWh, kVArh. Maximum demand current can be measured over preset
periods of up to 60minutes. The requisite current input(s) are obtained via current transformers (CT).
The SMARTconenct X835 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.
