The RTU7.4 is derived from a well-established series of compact RTUs from ELVAC a.s., designed for remote monitoring of energy networks, and further areas with high requirements for system reliability and robustness. The unit integrates three-phase measurement of voltages and currents (current inputs for 1A or 5A), digital inputs and outputs, a communication module and a charger of backup batteries. The unit can record the waveforms of signals from analog inputs triggered from fault events. Remote downloading of records, parameterization and FW upgrades are a matter of course. The RTU7KL PC2 version is fitted with a more powerful communication card to support more demanding communication tasks.
Typical applications;
* measurement of P, Q, U, I, 
* monitoring and control of renewable sources,
* monitoring and control of MV/LV substations, 
* protection
