ELECTREX LIBRA CCI UPS 5A PQ
Cod. PKA0716
Libra CCI CEI 0-16 UPS
Central Power Plant Controller (PPC / CCI)
The Libra CCI UPS is the Electrex solution for monitoring production plants in compliance with the CEI 0-16 standard,
annexes O–T, following the Arera 540/2021/R/EEL resolution and the subsequent 385/2025/R/EEL, which mandates
that photovoltaic and wind plants ≥ 100 kW, both new and existing and connected to the MV grid, must be equipped
with a Central Power Plant Controller (CCI) with the functionality of “Active Power Limitation on external DSO command” for
inverters (PF2).
The Libra CCI is a complete “Plug & Play” solution to collect plant information and securely transmit it to the distributor (DSO)
for monitoring and management of electrical loads, measurement of renewable energy production, other energy vectors, and
environmental parameters.
The Libra CCI meets all functional specifi cations required by CEI 0-16, namely:
• Mandatory: related to data exchange (P, Q) between the producer and DSO and the PF2 functionality (for plants ≥100 kWp)
• Optional: related to voltage and power regulation at the delivery point
• Voluntary: related to participation in the Dispatching Services Market.
The Libra CCI energy analyzer has a measurement accuracy class ≤ 0.2, as required in CEI 0-16:2025-04 Annex O (normative),
Central Power Plant Controller (CCI), section O.13.2.1.
The Libra CCI energy analyzer has a measurement accuracy class ≤ 0.2, as specified in the technical standard CEI
0-16:2025-04, Annex O (normative), Plant Central Controller (CCI), section O.13.2.1.
The Libra CCI can also be used as a starting point/master unit for more complex supervision systems, thanks to the ability to connect additional Electrex devices via RS485 subnetwork and/or Ethernet network. The Libra CCI is equipped with a real-time clock and memory for the
synchronous recording of energy and environmental vectors. Through the integrated Web Server, it is possible to supervise
the system by displaying instant measurements and graphical trends.
The Libra CCI includes an internal DC UPS (battery
backup) to ensure continuous power supply to the measurement system — a feature particularly recommended in cases
involving automated operations and/or alarms.
In addition, the Libra CCI is equipped with fi ve opto-isolated digital inputs
(for status and/or counting) and three relay digital outputs (for status and/or pulse control, with other versions available
upon request). It also manages Power Quality (PQ): detecting and recording various events in compliance with EN 50160
(voltage sags, swells, interruptions, harmonics) and EN 61000-4-30 Class S, with graphical event details, event tables and
time-lines, measurement campaigns with selectable parameters, and programmable sampling frequency.
