Module measuring the power of the moving CILK-UI

Description

Module is designed for measuring and processing of voltages and currents of electrical loadings, data change via the protocols Modbus RTU and RTM – 64/VAR with the supervisory level (information data transfer from the objects, reception of the setpoints and telecontrol commands).
