Description
Product Overviews
The rail-type multifunction electrical instrument with external Rogowski coil and split-core
current transformer is applicable for the energy-saving reconstruction project in high energy
consumption industries including the smelting, iron and steel, welding and semi-conductor industry.
It is also suitable for applications such as the power monitoring of grid-connected cabinet for
distributed photovoltaic power cabinet and energy demand management. It boasts of no need of bus removal,
easy connection and safe construction, saving reconstruction cost and raising efficiency for the user.
It integrates the measurements of all electric parameters including single-phase or three-phase
current, voltage, active power, reactive power, apparent power, frequency and power factorand
comprehensive energy monitoring and examination management. Meanwhile, it also has various peripheral
interfaces for the user to choose: the RS485 communication interface with MODBUS-RTU protocol can meet
the need of online communication management; the interfaces with switch input and relay output can
realize the remote signalling and remote control of the circuit breaker switch. It is very suitable
for real-time power monitoring system with an LCD display and the panel buttons to realize the setting
and control of parameters.
